1.4 Precautions
1. Prevent inflammables and liquids from entering scale head.
2. Always use the included wall transformer when using AC outlet. NEVER replace the wall transformer with a plug. This could
cause electrical shock and severely damage to the scale.
3. Allow clearance on all sides of scale platform for accurate weighing.
4. Do not drop large loads on scale platform.
5. NEVER EXCEED THE RATED CAPACITY OF THE SCALE.
6. Do not pull on the connecting electrical cables.
7. Make sure that the scale and ramps are properly secured to the floor (most models).
1.5 Best Conditions for Weighing
1. The scale should be level.

6
2. Best operating temperature is about 68 degrees F.
3. The weighing area should be kept clean and dry.
4. The surface that the scale is resting on should be of solid construction and not prone to vibrations.
5. Don’t install the scale near heater or air conditioner vents.
6. Avoid drafts.
7. Utilize a stable AC power supply. Avoid heavy motorized equipment on the same power line.
8. Do not operate the scale in close proximity of RF transmitters like cell phones and walkie-talkies.
9. Warm-up the scale before use.
1.6 Initial Set-Up and Operation
1. Carefully unpack scale from shipping carton. Save packing material for possible future use.
2. If the level legs are included separately, then screw one into each corner underneath the scale. If the level legs are already
screwed into the platform, they MUST be unscrewed and extended out so they can hold the platform above ground
3. Place scale on a level surface and adjust the level legs so that all four legs are touching the surface.
4. If your scale comes equipped with ramps, fix them to the floor using the mounting holes provided. This way the ramp will not
move during normal use. Be careful not to let the scale platform rub up against the ramp or any other surface, as this would
cause non-repeatability of other inaccuracies.
5. Plug into 117 VAC wall outlet. (If your model comes with the optional 24V DC input, please insert the appropriate power
supply). For non-battery pack equipped scales, wait for the weight screen to show up. For battery pack equipped scales, the
screen will remain blank until you press the ON/OFF key. To shut the scale down, press and hold the ON/OFF key until the
display blanks out.
6. Allow a five-minute warm-up time for stabilization and most accurate results. Items to be weighed may be placed anywhere
on the platform, but if heavy items are to be weighed, it is advisable to place them near the center. Many models are
equipped with shock absorbers and positive overload stops for protection. Still, care should be taken to avoid putting
excessive stress on the load cell system, as when heavy weights are dropped on the platform. It is normal for a small amount
of drift to occur over periods of time. For the most accurate readings, the scale may re-acquire a true zero by pressing the
ZERO button prior to weighing.
1.7 Platform Leveling Legs
Platforms will come with levelling legs that lifts the platform from the ground and provide the clearance for the internal load cell
sensors to bend. At shipping, these leveling legs are screwed into the platform tightly (with no clearance) to protect the platform and
the legs during shipping.
1.8 Multiple Indicators and Platforms
Indicators and Platforms must not be mixed and matched. Each indicator is calibrated towards a particular platform. If you purchased
and received multiple scales, then each indicator must be matched with its own platform. To do this, match the serial number on the
back of the indicator to the serial number on the platform. The platform’s serial number is usually located on the side of its frame or
under it.
2CONTROLS AND INDICATORS
2.1 Main Display Screen
The scale is equipped with 128x64 LCD Graphics Display with a wide viewing angle and variable contrast. For normal operations, you

3SYSTEM OPERATION
3.1 Basic Menu Operation
The scale operating system uses a menu driven interface that is both intuitive and easy to use. To access the setup menu, press the
MENU/BACK key.
There are two basic menu types. The first is a simple list of items. To select an item in the list, use the UP and DOWN ARROW keys to
line up on the desired item and then press ENTER.
The second type of menu is a horizontal list displayed along the bottom of the screen. These menu items indicate operations to be
performed. To select one, use the RIGHT and LEFT ARROW keys to select the desired item and then press ENTER. Horizontal menus
may show a single or double headed arrow on the right side to indicate that there are more selections to the left and/or right that are
not displayed.
Horizontal menus and lists are often used together to perform an operation on a specific item. For example, to delete a tare entry, use
the UP and DOWN ARROWS to select the desired tare from the list, then use the LEFT and RIGHT ARROWS to select the menu item
“DEL” in the horizontal menu. Pressing ENTER will perform the operation.
Selecting menu items will often lead to other menus, sometime drilling down several levels deep. Use the MENU/BACK key to back
your way out. Continuing back will eventually bring you back to the top, which is the main weight display screen. Consult the menu
tree in the back of the manual for help in navigating menus.
3.2 Tares
The tare function allows you to temporarily remove from the display any weight that may be on the platform. Tare weights are often
used in filling processes. For example, the user will place an empty box on the platform. The scale will indicate the weight of the box.
The user then presses the TARE key. The scale will now indicate a weight of zero, and will switch to the NET mode. The box can now be
filled. The scale will read out only the weight of the material. Switching to the GROSS mode will show the weight of the material plus
the weight of the box. To clear any active tare, press and hold the TARE key.

9
The TARE key can also allow you to quickly specify a weight that you want to tare out without going through the Tare Definitions
process. To set this function, please look at the Tare Button Function below.
Tares can also be taken, named, activated and stored permanently through the setup menu. Go to menu SETUP MENU/TARES. A list of
options is displayed on the screen:
Tare Definitions Create a record of predefined tares that can for pre-existing weights of containers.
Tare Settings Control the behavior of a tare.
Tare Button Function Control the behavior of the TARE Key on the Display.
Tares can also be taken, named, activated and stored permanently through the setup menu. Go to menu SETUP MENU → TARES. A list
of options is displayed on the screen, Tare Definitions and Tare Settings.
3.2.1 Tare Definitions
In this screen, a list of all tare definitions will be shown. To add a new tare, line up on NEW in the lower menu and then press ENTER. A
new tare will be added to the list with the default description of Tare #XXX. The number XXX is assigned by the system by counting up
the number of tares and then adding one. It is possible that after adding and deleting a few tares that two tares will have the same
description. This is acceptable, albeit confusing, and the description can be changed later. This new default tare will have a weight
value of 0.00lb when first created.
3.2.1.1 Editing Tares
You can edit any tare by using the arrow keys to line up on it and the “EDIT” function in the lower menu and then press ENTER. The
next screen will show the tare with its description and weight value in pounds. The lower menu allows you to change the description
(“DESCR”), enter the value directly (“VALUE”) or acquire it automatically from the platform (“ACQUI”).
3.2.1.2 Deleting Tares
To delete a tare from the list simply line up on it and the “DEL” function in the lower menu. Press ENTER to delete it. Once a tare has
been deleted it is removed permanently from memory.
3.2.1.3 Activating Tares
To activate a tare from the list, line up on it and the “ACTV” function in the lower menu, then press ENTER. The tare will be made
active, the scale switched to NET mode and you will immediately be placed back in the weighing screen you were in when you
accessed the setup menu.
3.2.1.4 Multiplatform Consideration
If the scale is equipped for multiple platforms, then the user is given the option to select which platform the tare will apply to. Use the
PLAT option on the lower menu to toggle between activated platforms that will apply to the current tare.
3.2.2 Tare Settings
In this screen, the way the tares behave can be changed. This also depends on what options you have installed in your system. The
selection settings can be changed using the horizontal menu at the bottom of the screen. The following selections apply.
3.2.2.1 Persistent Tare (For all scales)
Selecting this option to “Yes” will allow the scale to maintain the tare activation even when the power is recycled. This will apply to
both, stored tares and quick tares (tares from the keyboard). So, if the user activates a Tare from the Tare Definition Screen, and
recycles power, the scale will remember the last tare activated. Please note that when the scale is turned on the next time while a tare
has been activated, the scale will not show “0” with an empty platform. There will be negative number that will likely show up on the
screen corresponding to your tared value. Selecting this option to ”No” will remove the persistent tare feature. Tares will not be
remembered after power is recycled.

10
3.2.2.2 Analog Enabled (For Analog Output “4-20ma” equipped scales only)
By default, if the user tares a weight from the platform (and the screen shows zero weight), the analog output will continue to detect
the gross weight even if the screen shows zero, and therefore continues to produce the analog equivalent of the gross weight.
Selecting this option to “Yes” will allow the activated tares to affect the 4-20ma analog output. For example, if the user tares a weight
from the platform, and the screen shows zero weight, then this time, the analog output will produce 4ma (equivalent of 0 net weight).
In effect, enabling this option will allow the analog output to reflect exactly what is on screen regardless of the weight on the platform.
3.2.2.3 Setpoint Enabled (For Setpoint equipped scales only)
By default, if the user tares a weight from the platform (and the screen shows zero weight), the setpoint will continue to evaluate the
gross weight even if the screen shows zero, and therefore continues to control the outputs based on the gross weight. Selecting this
option to “Yes” will allow the activated tares to affect the setpoint evaluation. For example, if the user tares a weight from the
platform, and the screen shows zero weight, then this time, the setpoint will evaluate the command lines associated with the 0-net
weight. In effect, enabling this option will allow the setpoint to reflect exactly what is on screen regardless of the weight on the
platform.
3.2.3 Tare Button Function
The TARE key on the Front Panel of the Display Indicator can be used in two ways:
a) Tare any weight on the platform to bring the platform to NET ZERO.
b) Quick Tare: Quickly specify a tare weight that you want the scale to subtract from the current gross weight.
For situation (b) this is especially useful if you want to weigh pre-packaged items and you want to know weight of the content minus
the weight of the package. In this case, when you press the TARE button, a screen will show you to enter the weight of the package
you want to tare out. Once the tare is confirmed, the scale will display the weight of the content ONLY.
In the “Tare Button” screen, you will see the following:
Press ENTER key to enable or disable the Quick Tare function.

working configuration. Use this function and follow the prompts on screen to restore of your scale to a previous backed up
configuration.
3.4.3 Restore to Factory Defaults
If the scale is not performing properly, and all other troubleshooting methods have failed, then the last resort is to restore the scale
back to its factory calibrated settings. Use this function and follow the prompts on the scale to complete it.
To restore the scale back to Factory Defaults, perform the following steps:
1. Completely unplug the scale. Wait for a few minutes, then re-plug power to the scale.
2. Press the MENU button and go to SYSTEM. Press ENTER.
3. In the System Menu, scroll to SAW Scale Setup and then press ENTER.
4. Scroll down and select RESTORE TO FACTORY DEFAULTS. Press ENTER.
5. If there are any warnings that popup, just press ENTER to confirm.
6. If the Restore was successful, the scale will automatically reboot.
7. Wait for the scale to settle.
8. Place a test weight to see if the scale is reading appropriately.
3.4.4 Scale Description / Scale ID Number
Each scale can be assigned a unique description and ID number. This is useful for printing labels and other processes.
3.4.5 Udef Conversion Multiplier
Allows you to enter the multiplier (from pounds) for the user-defined conversion.
3.4.6 *Auto Increment Weight Number (Future expansion)
This number will increment each time the PRINT button is pressed. It can be useful in label printing and statistical operations. Its
starting value can be set here.
3.4.7 Display Contrast
This allows you to adjust the contrast of the display for optimum viewing.
3.4.8 Display Refresh Interval (or Display Update Speed)
The Display Refresh Interval can be adjusted from .1 to six seconds.
3.4.9 Startup Parameters
The following startup parameters can be set here.
❑The Startup Screen - Usually screen 1 which is the main weight screen. See the Main Display Screen to know which other
screens are available. Other screens that can be set are:
a. Screen 2 –The Tare Screen
b. Screen 3 –The Parts Counting-A Screen.
c. Screen 4 –The Parts Counting-B Screen.
d. Screen 5 –The Multiple Platform Screen.
❑The default Unit Conversion –Set the first unit to be displayed.
❑Zero lock can be enabled/disabled. Zero lock disables the front panel ZERO key. When this function is enabled the user must
press the ZERO and the PRINT key simultaneously to zero the scale.
3.4.10 Erase User Memory
The entire user memory can be erased at one time, if necessary, using this option. It will erase all user-defined tares, counting samples,
text definitions, print frames and setpoints but will leave platforms and other system memory intact.

12
3.4.11 Revision Number
This option reads out the current operating system revision number.
3.4.12 Auto Shut-Off
Auto Shut-Off allows you to set your scale to automatically shut off when a preset time limit has been reached and there has been no
activity on the scale. This feature is mainly used on battery pack equipped scales to prevent the battery from inadvertently being deep
discharged. Auto Shut-Off can also work on non-battery equipped scales but its operation is slightly different. In a battery equipped
scale the unit will completely shut down and the display will blank. The scale can later be turned on again using the normal means. On
non-battery equipped scales, the display will blank but the scale will remain in the same condition as when it shut down. Zero, active
tare and active parts counting sample as well as the current screen will all be retained. Pressing any key will return the scale to its
normal operating mode.
An inactive scale can be defined as no keys being pressed, and there has been no activity on the platform. It should be noted that
anything that causes a small increase or decrease in the platform reading will be considered an active platform. Avoid vibrating
surfaces, digital filtering constants of non-factory default values, or anything else that causes the platform reading to drift if this
feature is used.
To configure Auto Shut-Off, go to the menu SETUP MENU → SYSTEM → AUTO SHUT-OFF. There are two settable options available.
Activate –ACT Activates/deactivates the auto shutoff feature.
Time Interval –TIME Is the time, in minutes, that the unit will shutoff due to inactivity. Any time from 1 to 25 minutes can be
used.
3.4.13 Lbs-Oz Display
Enable the display to show the weight in “lbs and oz” instead of units in fractional form. For example, by default, the screen will 2 ½ lbs
of weight as 2.50 lbs. In “lbs/oz” form, it will show as “2lbs 8oz”. Please note that this does not affect the communication output form.
4CONFIGURATION AND CALIBRATION
4.1 Platform Advanced Setup
The scale’s operating system revolves around one or more platform definitions that are stored in memory, with most scales only
having one weighing platform. Each platform is fully configurable as to it capacity, displayed resolution, filtering, calibration and many
other parameters which will be outlined in detail below.
To access the Platform Setups, press the MENU/BACK key to activate the setup menu. Select PLATFORM SETUPS from the menu and
then press ENTER. If your scale has multi-platform capability then a list of platforms will be shown. If your scale is a single platform
type, then you will be shown only the Platform Setup Menu.
4.1.1 Description
A fourteen-character description can be assigned to the platform. The default description is “Plat#001”.
4.1.2 Platform Auto Setup
This setting should not be touched unless instructed by a Service Technician.
Auto Setup will erase all of the parameters for the selected platform and return it to the default state. It also erases the platform’s
span and cornering calibration. Auto setup is useful when the scale is first manufactured or when the user inadvertently changes a
calibration parameter that adversely affects the scale and then forgets the calibration parameter or its original value.
Upon activation, you will be presented with a selection of platform capacities and resolutions. Pick the appropriate entry and then
press ENTER. Auto setup will be performed. A span calibration is now necessary.

13
4.1.3 Span Calibration
Span calibration adjusts the platform’s sensitivity so that the display reads correctly. A calibrated weight is required to perform this
and the procedure is outlined below in the “Span Calibration” section.
4.1.4 Resolution-Overload
This setting should not be touched unless instructed by a Service Technician.
Each platform has the capability of displaying its reading in any of eight standard conversion units. Only four are enabled by default
and the user can enable the rest. The conversion units that are automatically enabled are pounds, kilograms, grams and ounces. The
remaining conversions are troy ounces, pennyweights, grains and a user defined conversion.
Each conversion unit’s resolution can be set individually. To do this, select RESOLUTION-OVERLOAD from the platform menu. A list of
conversions is displayed and each active conversion will have a check mark to its right.
Select the conversion you wish to modify and press ENTER. Use ACTV to activate/deactivate it, DPNT to change its decimal point
location and CNT to change what the least significant displayed digit will count by. In the pounds configuration (the scale’s native
conversion unit) you can use OVRL to set the overload limit in pounds.
When setting resolution (DPNT and CNT) care must be taken not to exceed 5000 total displayed counts or a drifting reading may result.
The maximum resolution is setup by default by auto setup but can be calculated easily by taking the scale’s maximum capacity and
dividing it by 5000. For example, a 50-pound scale’s resolution should be .01 pounds (50 / 5000 = .01).
4.1.5 Auto Zero
Auto Zero determines how the platform will zero on power up. The following selections apply.
Auto Zero –With this option selected, the scale will automatically zero out any weight on the platform. This is a good option for
environments that are not prone to power failures. Also, it is a great option if you always want to start the scale at zero regardless of
what the state of the platform (loaded or unloaded).
Last Zero –At initialization, the scale will zero out the platform to the last preserved zero state when the ZERO button was pressed.
This means that the scale remembers the last time the ZERO button was pressed. This results in the scale remembering the value of
the weight currently on its platform when the scale is shut off. In addition to that, suppose the weight was changed after the scale was
shut off, the next time the scale is turned out, it will show the new weight. This is an excellent option for environments prone to power
failures. It is also an excellent option if you need to constantly monitor the weight on the platform without interruptions.
None –The scale will initialize the platform based on its previous state. It is not a recommended to leave the scale in this option. The
scale may start up with an unknown state.
4.1.6 Zero Tracking
A scale sitting for long periods of time without weight on the platform is prone to drift from zero due to temperature changes and a
number of other factors. Generally, this is not a problem and you can press the ZERO button to return the reading to zero before
weighing. Zero tracking, when enabled, will detect small reading changes over time and correct the platform back to zero.
There are four settable options on the setup screen. To modify them, use the left and right arrow keys to line up on the appropriate
entry in the horizontal menu located at the bottom of the screen, and then press ENTER. These menu items are as follows:
Active –ACTV: Activates or deactivates Zero Tracking.
Window –WIND: This is the window range above or below the current ZERO point that needs to be continuously compensated (up to
20% of full capacity) to correct zero shift. For example, over two days, you notice that the scale has shifted in weight by 0.2lbs, even
though there is no weight on the platform (and was originally reading perfect 0) or a weight that was constant over two days is now
reading 0.2lbs over. This is known as “Zero Shift” and can be corrected using Zero

14
Tracking. After studying the scale’s behavior on this aspect, we can plug this 0.2lb range in this Window field. Now you will notice that
your scale will zero out any deviations that falls within ±0.2lbs.
Noise Count –NCNT: This is the noise count of filtering mechanism. This sets the number of weight values that need to be discarded
before considering that the new weight value is a new value and not part of the current weight value tracking process. The higher this
number, the less accurate the weight value, the faster your performance.
4.1.7 Software Filter
The raw internal reading from the load sensor contains electronic noise and other factors that can cause the reading to be drifty and
non-repeatable. All electronic scales incorporate some sort of filtering to compensate for this. Another use for filtering is to help
stabilize a scale when it is used on a surface that is vibrating, in windy conditions, when subjected to RF interference or when used on
a noisy power line. Your scale has two stages of filtering. The first is an electronic filter that is permanently enabled and the second is
the software filter which is fully configurable.
In general, a low degree of filtering will cause the scale to be quick to react but prone to noise and vibrations. Heavy filtering will
eliminate the noise and vibrations but the platform will react slowly to changes in weight. We have by default set up the optimum
filtering parameters for general use. These should only be changed in extreme circumstances.
There are four settable options on the setup screen. To modify them, use the left and right arrow keys to line up on the appropriate
entry in the horizontal menu located at the bottom of the screen, and then press ENTER. These menu items are as follows:
Active –ACTV: Activates or deactivates Software Filter.
Buffer –BUFFER: These are the number of averaging slots in the software filter. The higher this number, the slower the filtering
process, the more accurate the weight reading.
Window –WIND: Set's the weight value window at which you want the filtering to take place. The standard value for this field could
be the scale's resolution. So, if your scale is at a resolution of 0.02 lb, then set that value to this window. By default, the value has been
set in factory.
If you set a lower value than the resolution of the scale, then the scale will be stricter in its filtering and almost all values from the
platform will be hitting the noise count giving you a much slower performance.
Set a higher value and the scale will be more lenient in its filtering allowing more noisy values to pass through for processing giving you
a better performance but higher inaccuracy in readability. The best way to approach this window is determining the range of
fluctuation with the default setting. For example, by observing the scale, you notice that your scale is varying by 1lb. If that is the case,
then set the value here to 1lb. You will then get stable readings within this range.
Noise Count –NCNT: This is the noise count of filtering mechanism. This sets the number of weight values that need to be discarded
before considering that the new weight value is a new value and not part of the current weight value averaging process. The higher
this number, the less accurate the weight value, the faster your performance.
4.1.8 Stability Control
If the scale display values are not stable due to a noisy or unstable environment and you do not want to estimate the actual value of
the weight on the platform, the scale can estimate it for you.
Stability Control is not by any means a filtering mechanism. This feature should only be used if you know that the scale will always be
unstable or in constant noise. What this feature does is lock in an appropriate weight based on the stability count and a stability
window you have specified in this screen. The weight locked, may not be the most accurate weight of the object placed on the
platform, but it is a best guess as computed by the Stability Control in this scale. Once the stability lock has been placed, the lock will
not be removed until the platform experiences a weight change greater than the stability window. There are four settable options on
the setup screen.

15
Active –ACTV: Activates or deactivates Stability Control.
Source –SRC: This sets the primary source of readings that the Stability Control mechanism will use to estimate the best lock-in
weight. There are two selections here:
❑A/D Reading - This selection makes the Stability Control mechanism take readings unfiltered and straight from the load cell.
This is the fastest and the least complex selection and therefore the default.
❑Filtered - This selection is an advanced selection. With this selection, Stability control uses filtered weights based on
parameters set by the Software filter. Selecting this option automatically activates software filter. Make sure the parameters
in Software filter are properly set or the scale will behave erratically. Use this selection only if you know what you are doing.
Window –WIND: The Window field operates similarly as explained in the Software Filter section.
S.C. Count –CNT: This number indicates the number of stable readings within the window set above to qualify a lock in. Suppose this
number is set to 3, then the Stability Control mechanism will try to read 3 readings consecutively that are within the window above. If
they fall within that window, then the weight will lock in, else, it will reset and start over until it gets 3 stable readings.
Noise Count –NCNT: This is the noise count of filtering mechanism. This sets the number of weight values that need to be discarded
before considering that the new weight value is a new value and not part of the current weight value averaging process. The higher
this number, the less accurate the weight value, the faster your performance.
After Stability Control is activated, an “S” appears at the bottom left of the screen during normal weight readings. While the scale does
not have a stable reading, the S will appear crossed out. As soon as a weight has been found, it will lock this weight and the S will be
uncrossed. Once the lock has been obtained, the reading will not budge until a weight change greater than the window set has
occurred.
4.1.9 Zero / Motion Detect
This scale can detect if there is motion on the platform. There are four settable options on the setup screen. The first three are for the
motion detect setup. The fourth option controls the zero indicator on the main display. To modify them, use the left and right arrow
keys to line up on the appropriate entry in the horizontal menu located at the bottom of the screen, and then press ENTER.
Active –ACTV: Activates or deactivates motion detection.
Motion Window –MOTN: The Motion field determines the range of weight at which you want to define “motion”. So, if the scale has
been set on a moving truck, and you have determined that the scale always is within a certain weight range when the truck is moving
normally at normal speeds, you would want to set the Motion window at that range. For example, say you have put a weight on the
scale that would read 20lbs on a stable surface. But on the truck, it reads 18-23lbs. This means that your motion window is 5lbs. So
now you know that you want to detect motion if and only if it is greater than 5lbs, so you can set the Motion window to 5lbs.
Time Interval –TIME: This works along with Motion Window to detect a stable reading. The reading must be stable within the motion
window for this length of time (in seconds) in order to be considered a stable reading. As long as the weight remains within specified
motion window within this time, the scale would confirm that there is no motion detected. If the weight jumps out of the motion
window, then the scale would register as “Motion Detected” and reset the time interval.
Zero Window –ZERO: This controls how close the scale needs to be to the true zero point before lighting the zero indicator (ZR) on the
bottom of the main display. For example, if you set the window to 1lb, then any weight from 0lb to 1lb will register as ZR (meaning
ZERO condition).
After ZERO/MOTION DETECT is activated, the scale needs to be rebooted for this option to take effect. After reboot, a tiny ‘’
indicator appears at the bottom of the screen. If the platform is moving, the ‘’ indicator will show as it is seen here. If the platform is
within the bounds of ‘No Motion’ as set here, then the ‘⚫’ indicator will be crossed out.

16
4.1.10 Multi-Platform Settings (for Multiple Platform Configurations Only)
This screen allows you to configure the scale to calculate the “Sum” or the “Difference” between the weights of two connected
platforms.
You can also configure the scale to automatically scroll through all platforms at specific intervals. This means that after a certain
periodic interval, the scale will show the individual weight on each platform alternatively.
The following settings apply:
Platform Total –TOTAL: Toggle this option to select either “Sum” or “Diff” function between the weights of both platforms. For “Diff”,
the equation is: PLATFORM 1 –PLATFORM 2 = DIFFERENCE.
Auto Scroll –SCROL: Use this option to toggle the Auto Scroll Enable option.
Auto Scroll Time (sec.) –TIME: Set the time period between each platform display interval.
4.1.11 Adjust Zero Offset
Use this function to reset the Calibration Zero Constant. This is similar to the first part of the Span Calibration procedure except you do
not need a known weight for calibration. However, it is required that the platform remain empty during this process.
4.1.12 View Raw ADC Data
This function is used for troubleshooting purposes. If the calibration is done improperly or if the scale is installed incorrectly, then the
weight value seen on the screen maybe off or not reading at all (showing 0). To make it easier to self-troubleshoot this issue, this
screen allows to first check if the scale analog conversion hardware is still in working order.
The screen shows the raw, unprocessed digital counts coming from the analog to digital converter (ADC). The ADC is directly
connected to the load cells. The behavior of the platform directly affects these numbers. Here is an overview what the numbers mean:
a) 83884xx –The last two digits should be constantly moving. This means the ADC is working properly but the platform is not
connected to the indicator. Please check the platform cable and try again.
b) 8xxxxxx –If these numbers don’t equal to the number in part (a), and the last two digits are constantly moving, then it means
the platform is connected properly.
oPress the Platform with your hand.
▪If the numbers are increasing then the legs are screwed in at the right level.
▪If the numbers are decreasing, then the legs are screwed in all the way. Unscrew the legs out a little so that
the platform is “floating” above the ground. If you have installed the load cells on your own, then this
means one or more of the load cells have been installed upside down.
oIf all the items above check out, then just perform a Span Calibration of the scale to get back to working condition.
c) 0000000 –The ADC is damaged. Please call Customer Service for further assistance.
16777215 –Something is wrong with the ADC configuration. Perform a Restore to Factory Defaults to attempt to fix this issue.
If it doesn’t work, call Customer Service for further assistance.
5CALIBRATION AND TROUBLESHOOTING
Your scale has been precisely calibrated at the factory before shipping. It has the capability to adjust its own calibration to a certain
degree to compensate for aging electronics, and temperature changes. This being the case, it is possible that you will never have to
calibrate the scale. Doing so may leave you with a worse calibration than you started with. Does your scale really need to be
calibrated? If so what steps are needed? Follow the steps outlined below to help make this determination.
Try to troubleshoot the scale using the “View Raw ADC Data” feature in conjunction with the below checks.

17
5.1 Scale reads zero and will not move.
❑Make sure that any and all shipping screws are removed from the platform.
❑On platform scales, check that all four level legs are contacting solidly against the floor.
❑If level legs are screwed in all the way then the stud from the level leg may be contacting the underside of the platform not
allowing the load sensor to flex.
5.2 Scale reading is fluctuating wildly.
❑Scale must be on a non-vibrating surface. Breezes may affect scales of lighter capacities.
❑Scale must be installed on a clean power line. Electric motors, computers or any other devices can cause power line
interference.
❑RF interference can cause scale readings to fluctuate. Are there any transmitters nearby like cell phones or walkie-talkies?
❑If the scale is a remote platform type, check to see if the cable from the platform to the indicator in plugged in properly. If so
then remove the plug temporarily to check for bent or missing pins.
❑Check for nicks or cuts on the platform cable.
5.3 Scale reading is different on different areas on the platform?
❑On platform scales, check that all four level legs are solid against the floor. If a level leg is screwed in all the way then the stud
from the level leg may be contacting the underside of the platform not allowing the load sensor to flex.
❑Check for any mechanical interference. Is there anything rubbing against the platform?
5.4 Scale corners properly but does not indicate the correct weight.
❑On platform scales check that all four level legs are solid against the floor.
❑Check for any mechanical interference. Is there anything rubbing against the platform?
❑Perform span calibration.
5.5 Span Calibration
Span calibration is used to set the internal gain of the indicator so that it reads correctly. A calibrated weight is needed in order to
perform a span calibration. Any weight may be used within the capacity range of the scale but a weight of 50% of capacity is
recommended. Using weights of less than 10% of capacity is not recommended and may lead to an inaccurate calibration. The
following sequence walks you through Full Calibration.
1. Press MENU button (#5) ---- setup menu screen will appear
2. Scroll to PLATFORM SETUPS and press ENTER.
3. In the Platform Setups Menu, scroll to SPAN CALIBRATION and press ENTER.
4. The next warning message warns you about the consequences of performing an incorrect calibration. Read the warning
message, and then press ENTER
5. Input the calibration weight on the space provided. The calibration weight must be at least 50% of full capacity. If you make a
mistake, press ZERO until the mistake clears.
6. Press ENTER to confirm input of calibration weight.
7. Remove all weight from the platform. The current weight is shown at the top left side of the screen. Make sure that the
reading is as stable as it can be. Then press ENTER.
8. Wait for the next prompt to appear.
9. When the prompt appears, place the known weight on the platform.
10. Wait for the raw count on the top left side of the screen to stabilize (about 5 seconds). Press ENTER to confirm the placing of
weight.
11. Wait for a few seconds until the calibration procedure completes.
12. Press MENU/BACK to go all the way back to the weight screen.
