Introducon
The Model 4215-HS is a versale precision instrument intended for the digital readout of strain gage sensors
such as load cells. Opcal encoders are also supported.
Features:
* Full bi-polar 6 digit display (±999,999) using two line, 20 character, vacuum uorescent display for clear, pre-
cise indicaon of measured quanes and limit status.
* No knobs or dials. No internal jumpers. All adjustment and calibraon is done using user-friendly front panel
menus. Keylock opon to prevent accidental or unauthorized changes to the unit’s setup.
* Measure load in pounds, kilograms, Newtons, PSI, MegaPascals, kilo-pounds, kiloNewtons, metric tons,
mV/V, or grams. User dened base area for PSI and MPa. Tare at any me.
* Capture the load peak and valley, display in pounds, kilograms, Newtons, PSI, MegaPascals, kilo-pounds,
kilo-Newtons, metric tons, or mV/V. Reset at any me.
* Measure posion and velocity with oponal encoder input. Display in English units, metric units, or in per-
cent of a user dened base length. Reset at any me.
* Four contact closure Limit switches. You can set which signal drives the limit (load, peak, valley, posion,
or velocity), normally open / normally closed, set point, and manual reset (latched) or automac reset (not
latched).

* Print current readings of load, peak, valley, posion, and velocity using the currently selected units at the
touch of one buon.
* Automac idencaon of calibrated load cells with auto-id opon.
* Calibraon for load cells using manufacturer’s milli-volt per volt calibraon factor, 5 point milli-volt per volt,
2 or 5 point known mass, or internal precision shunt calibraon. A back panel switch allows you to choose be-
tween two values used for the shunt calibraon so there is no need to open the unit.
* Two Channels of Analog output of any signal (load, peak, valley, posion, velocity) with user dened scale
factor and oset. Large, buered ± 10.00 volt output.
* Remote operaon using standard RS232 ASCII command set.
* Back panel digital inputs for tare, peak and valley reset, posion reset, and print. Other funcons available as
custom programmed opons.
* Oponally measure the average force using a contact closure to begin and end the averaging period.
This secon will help you get your Model 4215-HS set up and operang in just a couple of minutes. The back
panel is shown below. You will need to make at least two connecons here. First be sure that the power switch
is o (the lower part of the rocker should be pressed in). Connect the AC power line and plug it in.
Next connect a load cell to the 9 pin female connector labeled “Sensor A”. You should use the cabling supplied
with your Model 4215-HS and load cell. If you do not have a factory supplied cable, see Appendix B for the
recommended load cell connecon.

Item Buon
The Item buon cycles through the list of dierent items that can be displayed (Load A, Peak A, Vall A, Load B,
Peak B, Vall B, Pos, Vel, Limits, and oponal Avg A and Avg B). Use the Unit buon to change the units that are
used for the currently displayed item.
Tare Buon
The Tare buon sets the current load to zero for channel A, channel B, or channels A and B. A submenu will
allow you to select what channel you want to tare. It does not maer what is being displayed when you press
this buon. The load is always reset to zero. A single channel unit will automacally set Load A to zero.
Reset Buon
The Reset buon brings up a list of things that you might want to set to zero:
If this is a 2-channel unit, the following menu will appear:
> Reset Ch A + Ch B will reset the peak, valley, max, min for channels A and B.
> Reset Ch A Only will reset the peak and valley for channel A.
> Reset Ch B Only will reset the max and min for channel B.
> Reset Posion will reset the posion to zero.
> Reset Limits will reset any limits that require manual reseng.
For a single channel unit, the following menu will appear:
> Reset Peak+Vall will reset the peak and valley measurements.
> Reset Peak Only will reset the peak measurement.
> Reset Vall Only will reset the valley measurement.
> Reset Posion will reset the posion to zero.
> Reset Limits will reset any limits that require manual reseng.
Pressing either the “+” buon or the “>“ buon will scroll forward through this list. Pressing either the “-” but-
ton or the “<“ buon will scroll backward through the list. Pressing “Enter” will reset the currently displayed
item.
Pressing “Esc” will return to Run Mode without reseng anything. Note that all menu lists on the Model
4215-HS start with the “>“ symbol and that the Esc buon will always back out of a menu without making any
changes.

View Buon
The View buon switches between two virtual displays stored in the memory. Each of these displays will re-
member the units you have selected for each item, and which item is currently being shown. This may save you
from scrolling through the list of items if there are two parcular results that you oen use. For instance you
might set the display to show Load in Lb, press View, and then set the display for Peak in PSI. Repeated press-
es of the View buon will now switch back and forth between Load in Lb and Peak in PSI with a single buon
push. If you choose to have the second line show a display, then the View buon toggles between the display
currently being acvated. The acvated display will have a “>” symbol to the le of it.
Print Buon
T The Print buon will send a set of data to the printer. This will contain the current readings of load, peak, val-
ley, posion, velocity, and limit status. The units used for prinng will be the units last selected on the numeri-
cal display.
The printer must be a serial printer that supports ESC/P protocol. Many Epson printers with serial ports are
known to be compable.
Appendix B gives the pin assignments on the serial connector.
Unit Buon
The Unit buon cycles through the list of units that are available for the item that is currently being displayed.

Setup Mode
Setup mode is used to change the setup of the Model 4215-HS. To enter setup mode press the two end but-
tons at the same me ( “<“ and “>“ ). The row of four buons will now funcon as indicated by the lower set of
labels (Plus, Minus, Enter, and Escape).
If the oponal keylock is in the locked posion you will see “>Setup is Locked” when you try to enter setup
mode. This prevents accidental or unauthorized changes to the setup of the unit.
To exit from setup mode and return to run mode press the escape buon (Esc). When you are entering numer-
ical data or selecng opons from a sub-menu the escape buon will back you out without making any chang-
es.
The main menu in setup mode contains the following 6 entries which will be described in detail in the follow-
ing secons. Note that all main menu items begin with the “>“ symbol and that all submenu items begin with
the “>>“ symbol.
• > User Data Entry -- allows you to set any common math opons such as the base area used to display load
in PSI or the base length used to display posion in percent.
• > Analog Output -- is used to select the analog channel, source, and scaling for the analog output channels.
• > Sensor Select -- lets you manually set which load cell calibraon data is used. If you use auto-id load cells
you will never need this menu.
• > Calibraon -- provides access to calibraon for load cells, extension sensor, or opcal encoders.
• > Limits -- allows you to set the source and opons for the 4 contact closure switches.
• > System Opons -- contains entries to set the printer baud rate, enable or disable automac sensor iden-
caon, enable or disable automac load zeroing, and to set the serial communicaons address, baud rate, and
line feed opons.
• > Display Opons -- lets you choose the ltering that is applied to the load measurements, the number of
decimal digits that are shown on the display and on the print, the count by values for channels A and B (1, 2,
5, 10, or 20), and whether the second line of the display shows the limit switch status, a blank line, another
display, or text.
The Plus or Right buon ( “+” or “>“ ) will scroll forward through this menu. The Minus or Le buon ( “-” or
“<“ ) will scroll backward through this menu. The Enter buon selects the currently displayed menu item. The
Esc buon will return you to Run Mode.
Entering Numerical Data
At mes you will need to enter numerical data into the Model 4215-HS. The method is consistent in all cases. A
number is presented on the le side of the display with an underline cursor.

Entering Numerical Data
At mes you will need to enter numerical data into the Model 4215-HS. The method is consistent in all cases. A
number is presented on the le side of the display with an underline cursor.
• Le ( “<“ ) moves the cursor le one posion. If you are on the lemost digit a new zero will be added. Thus
10.000 will become 010.00 where the cursor has moved from the tens place to the hundreds place.
• Right ( “>“ ) moves the cursor right one posion. If you are at the far right a new decimal will be added if
there is room. Thus 12.34 will become 12.340 where the cursor has moved from the tenths to the hundredths
place.
• Plus ( “+” ) increments the digit above the cursor. Thus 12.34 becomes 13.34. Note that 9 will “wrap around”
to 0.
• Minus ( “-” ) decrements the digit above the cursor. Thus 12.34 becomes 11.34. Note that 0 will “wrap
around” to 9.
• Plus and Minus (both “+” and “-” at the same me). This will change the sign of the number. Thus 12.34 be-
comes -12.34. Note that cursor posion does not maer when you change the sign.
• Enter accepts the currently displayed number.
• Esc escapes from numerical entry and discards any changes that have been made.
>User Data Entry
This menu is used to enter numerical constants used by the math opons. These constants are listed in a sub-
menu that works exactly like the main setup mode menu. Typical items in this submenu are:
>>Base Area Ch A
This is the area in square inches that is used to calculate load in pounds per square inch (PSI) or Mega Pascals
(MPa).
>>Base Length
This is the length in inches that is used to calculate posion in percent.

>Analog Output Channels
This menu is used to set up the analog outputs. Instead of a submenu there is a series of selecons. Pressing
escape at any me will leave the analog output unchanged and return you to the setup mode main menu.
1. Channel: -- This entry allows you to select the analog output channel A or B. (use either the le/right or
plus/minus buons) for the selected source data that will drive the analog output. Press enter to select the
displayed Analog channel.
2. Source: -- This entry allows you to scroll through a list (using the le/right or plus/minus buons) to select
the source of the data that will drive the analog output. The standard list will include load, peak, valley, posi-
on, and velocity. Press enter to select the displayed item.
3. Units: -- This entry allows you to scroll through the list of available units for the data source you have chosen
in the previous step.
4. Full -- This entry species the value of source data (in the selected units) that will cause the Model 4215-HS
to output posive full scale analog voltage (+10.0 volts).
5. Zero -- This entry species the value of source data (in the selected units) that will cause the Model 4215-HS
to output zero analog voltage (0.0 volts).
Once you have entered these 4 selecons the analog output is setup.
>Sensor Select
This menu is used to manually select load cell calibraon data from a list stored in the Model 4215-HS. When
you select this menu on a 2 channel unit, you are asked to select Channel A or B. The load cell serial number of
the selected channel is displayed. Use either the le/right or plus/minus buons to page through the list. The
escape buon will return to the setup mode main menu without changing the load cell that is selected. The
enter buon will select the currently displayed load cell and briey display the rated load, last calibraon date,
and excitaon voltage.
To add new load cells to this list use the Calibraon entry on the setup mode main menu described below.
If you are using auto-id load cells this menu will allow you to see which load cell is selected but will not allow
you to change the selecon. This ensures that the correct calibraon informaonis always used when you use
Auto-ID load cells.

Sensor Delete
The Model 4215-HS can store calibraon data for 4 dierent load cells / sensors (25 slots oponal). To delete
a load cell from this list choose “>Sensor Select” from the setup mode main menu. Press the le/right or plus/
minus keys unl the serial number of the cell you wish to delete is displayed. (You may need to shut o auto-id
if it is on, see the System Opons menu for details). Then press both the plus and minus keys at the same me.
The Model 4215-HS will ask “Delete Sensor?” to be sure that you intend to delete this calibraon data. Press-
ing Enter will delete the cell data from the list. Pressing Escape will return to the load cell select without chang-
ing the list.
>Calibraon
This menu is used to access all methods of calibraon that are supported by the Model 4215-HS. Selecng cal-
ibraon from the setup mode main menu will bring up a submenu. This submenu is used exactly like the main
menu. Press le/right or plus/minus to change the menu item. Press escape to return to the setup mode main
menu. Press enter to select the displayed menu item.
If you are re-calibrang a load cell, the Model 4215-HS will recognize it using either the autoid or a manually
entered serial number. Any me you overwrite exisng load cell calibraon data you will rst be warned with
the “Overwrite Data?” message. Pressing enter will overwrite; pressing escape will cancel the calibraon. An-
other method of overwring exisng data is to delete the sensor rst and then calibrate.
If a load cell with a new serial number (or new auto-id) is calibrated the data is added as a new entry in the
load cell list.
>>Cal Check
Selecng this item will run a calibraon check on the load cell / sensor aached to Channel A or B. The Model
4215-HS will measure the shunt value of the load cell and compare it to the shunt value that was recorded
when the load cell was last calibrated. The rated load and last calibraon date for the load cell are displayed
followed by the currently measured shunt value and the shunt value that was recorded when the load cell was
calibrated.
Note that the Model 4215-HS has a switch on the back panel that allows you to select either a 30K shunt or a
60K shunt. Be sure that this switch is set correctly for the load cell that you are using.
Since this shunt check electronically applies approximately half the rated load, it is important that the load cell
/ sensor is not loaded when this check is run. If you see the “Cell Overloaded” message, remove any load on
the cell and try the check again.

>>Cal by mV/volt
This item is used to calibrate a cell using the manufacturer’s milli-volt per volt calibraon factor or a series
of milli-volt per volt points with corresponding masses (usually listed on the load cell calibraon cercate).
Before you enter in the desired informaon, another menu will ask if you want to calibrate by milli-volt per
volt or 5 Point milli-volt per volt. You will be asked for the channel, the cell serial number, the current date,
the calibraon unit, the cell’s maximum rated load, and the desired excitaon voltage (5.0 or 10.0 volts). If
milli-volt per volt calibraon was selected, you are then prompted to enter the manufacturer’s milli-volt value.
If 5 point milli-volt per volt calibraon was selected, you are prompted for each mass and milli-volt per volt
value. One of these points should be zero mass and zero milli-volts per volt. Enter each of these selecons or
press the escape buon at any me to return to the setup mode main menu without changing the calibraon.
The cell should not be under load when this calibraon method is used since a shunt value will be measured
and recorded for later use with the “Cal Check” feature described above. The “No Masses Ready” message is
intended to remind you of this fact.
>> Cal by Masses
This item is used to calibrate a load cell, channel A, using two known masses. Before you enter in the desired
informaon, another menu will ask if you want to calibrate by 2 Point, 5 Point, or 10 Point (Non standard
oponal conguraon) You will then be asked for the channel, the load cell serial number, the date, the cali-
braon unit, the cell’s maximum rated load, and the desired excitaon voltage (5.0 or 10.0 volts). You are then
prompted to enter the value of the rst mass. The “Mass 1 Ready?” message will wait while you actually hang
the mass. When the Model 4215-HS is reading the load cell it will display the “Reading...” message for about 10
seconds. During this me, it is important that the masses are not disturbed since all the readings taken are av-
eraged together to obtain the calibraon data. The second mass is then entered and read. If 5 Point calibraon
was selected, the process will connue unl all masses have been read. A “No Masses” reading is also required
during which me a shunt check value is recorded.
>>Cal by Shunt Val
This item is used to calibrate a load cell using the manufacturer’s shunt calibraon factor expressed in pounds.
You will be asked for the channel, the load cell serial number, the date, the calibraon unit, the cell’s maximum
rated load, the desired excitaon voltage (5.0 or 10.0 volts), and the shunt calibraon constant. The Model
4215-HS will then automacally perform the shunt calibraon of the load cell using its internal precision shunt
resistor. Note that there is a back panel switch that allows you to select either a 30K or 60K resistor for shunt
measurements (see Appendix B for a circuit diagram). Be sure to select the appropriate value for your load cell.
During this calibraon the “Reading...” message will be displayed. Do not disturb the load cell while it is being
read. Like the “Cal by mV/volt” opon, the load cell should be free of load during this calibraon.

>>Counts per Inch
This entry allows you to set the number of counts per inch that the quadrature encoder input will use.
>Limits
This menu is used to set up the 4 contact closure switches. Instead of a submenu there are a series of selec-
ons. Pressing Enter will accept the displayed entry. Pressing Escape will return to the setup mode main menu
without changing the limit setup.
1. Select Limit X -- The rst selecon chooses which of the limits you want to set up (1-4). Use the le/right or
plus/minus buons to change the number. Press enter to accept the displayed number. Press escape to return
to the setup mode main menu.
2. Normally Open / Closed -- This selecon determines if the switch contacts are open or closed when the limit
is de-acvated.
3. Enabled / Disabled -- Choosing enable allows the limit to operate as specied by the following selecons.
Choosing disable places the limit in its “normal” state and completes the limit setup.
4. Source: -- This selecon allows you to scroll through a list (use either the le/right or plus/minus buons) to
select the source of the data that will drive the limit. The standard list will include load, peak, valley, posion,
velocity and, oponally, average force. Press enter to select the displayed item.
5. Units: -- This entry allows you to scroll through the list of available units for the data source you have chosen
in the previous step.
6. Set -- This is the numerical value of the source at which the limit will be acvated (set point). It is specied
in the units you chose in the previous step.
7. Trip if source < / > Set -- Choosing source>set means that the limit will be acvated when the source be-
comes larger than the set point. Choosing source<set means the limit will be acvated when the source be-
comes less than the set point.
8. Latching on/o -- Selecng latching o means that the limit will be de-acvated automacally when the
source passes the reset point (see next selecon). Selecng latching on means that once the limit is acvated
you must manually reset it using the Reset buon. If you select latching on then the limit setup is done.
9. Rst -- This selecon determines the numerical value of the source at which the limit will be deacvated (re-
set point). If you selected “source>set” in step 7 then the limit is deacvated when the source is less than the
reset point. If you selected “source<set” in step 7 then the limit is deacvated when the source is greater than
the reset point

Notes:
The Set and Reset condions for each limit are evaluated independently. If both condions are met then Reset
will take priority over Set.
Limit status may show an asterisk if the limit is enabled but there is an error in the signal source. For example,
if the limit source is load but there are no load cells currently calibrated, or the load cell has a rang of 0.0 Lb,
or a millivolt per volt constant of zero. Another example would be if the limit source is posion and zero has
been entered for the encoder counts-per-inch constant. Limits that are in this error condion will be forced to
the o posion as if they were disabled.
>System Opons
This menu contains some system wide parameters that are seldom changed. These are listed in a submenu
that works exactly like the setup mode main menu.
>>Printer Baud
The front panel print buon and the RS232 print commands will use this baud rate for communicaon with
your printer. This seng has no eect on units that are not equipped with the prinng opon. 57.6 K baud is
commonly used on older serial printers 230.4 K baud is used on more recent serial printers.
>>Auto Idenfy / TEDS Capability
This allows you to turn automac load cell idencaon on or o. Usually you can leave auto-id on even if
you never use automac load cell idencaon. In order to use this funcon you must either have an au-
to-id equipped load cell or use an in-line auto-id module aached to your load cell cable (TEDS). Meters can
be equiped with TEDS Template 40 and 41 read & write capability. Template 40 and 41 are avaialble in the
“4215-HS-Enahanced Model”.
>>Auto Zero Ch A/B
This menu lets you enable or disable auto zeroing for load measurements on Channel A or B. When enabled
this funcon will tare the load to zero any me that it has remained within 10 counts of zero on the display for
10 seconds..
>>Com Address
This item allows you to set the address of this unit used for the RS232 ASCII command set. Valid values are 1
through 254. If the RS232 mul-drop opon is installed you must be sure that all the aached units have dier-
ent addresses to prevent data collisions.

>>Com Baudrate
This sets the baud rate for the RS232 ASCII command set. Available values are: 300, 600, 1200, 2400, 4800,
9600, and 19.2k. Note that the “Special” entry is reserved for future use.
>>Com Line Feed
This controls whether a line feed is added to each carriage return that is sent out by the Model 4215-HS when
the RS232 ASCII command set is being used.
>>Retain Tare
This controls whether the most recent tare value is retained through power down of the unit and used again
immediately on power up. Choosing this opon will retain tare on channel A in a single channel unit and both
channels A and B in a twochannel unit.
>>Display Opons
This menu contains opons that eect how load, peak, and valley are displayed and printed. These are listed in
a submenu that works exactly like the setup mode main menu.
>> Filter Select
There are two types of lters available on the Model 4215-HS: Type I, and Type II. Type I lters are good for
removing most kinds of noise but may leave some jier on the end digits. Type II are more advanced lters
that are opmized for the typical industrial environment. Both lter types allow you to select from 4 levels of
ltering with Level 1 being the least ltering and Level 4 being the most ltering.
The seling me for each of the 4 levels of ltering is shown in the table below.
Level 1 2 2 4
Setting Time (seconds) <1 2 10 30
Read Rate (per second) 60 60 30 10

>>Decimals Ch A/B
This lets you set the maximum number of digits to the right of the decimal that are displayed or printed for
load, peak, and valley. When large load cells are selected the number of decimal digits shown may be limited,
for example a 100 Lb cell will allow 3 digits, while a 1000 Lb cell will only allow 2 digits. Also if a number is too
large to t on the display some decimal digits may be dropped (the display will “auto-range”). The number of
digits shown for posion data depends only on the number of counts per inch of the encoder and is not eect-
ed by this seng.
>>Second Line
This opon allows you to choose what you want to have displayed on the second line. You can select limits,
select a display, select text, or leave the line blank.

Digital Inputs
There are 4 digital inputs available on the Model 4215-HS. They are accessible on the Digital I/O connector on
the back panel (pins 9 - 16). These inputs are individually optoisolated and include current liming resistors. An
input voltage anywhere from +4 to +22 volts DC may be used to obtain the “on” state. See Appendix B for a full
descripon of the Digital I/O connector. If you do not require isolaon for your applicaon you can use the +5
or +12 volt and GND available on the Digital I/O connector (pins 24-26).
These 4 inputs are called IN1 through IN4 and have the following standard funcons:
• IN1 will Tare the Load to zero while it is in the On state.
• IN2 will Reset the Peak and Valley measurements while it is in the On state.
• IN3 will Reset the Posion measurement while it is in the On state.
• IN4 will send one set of measurements (load, peak, valley, posion, velocity, and limits) to the serial printer
when it transions from O to On.
Other funcons may be assigned to these inputs by custom programming at the factory.
RS232 Operaon
All the features and sengs of the Model 4215-HS can be accessed remotely using the RS232 ASCII command
set. These commands fall into two groups: commands that are like Run Mode, and commands are like Setup
Mode.
The Model 4215-HS supports remote operaon using a standard RS232 Interface consisng of ASCII characters.
The baud rate is set using the Com Baudrate item on the System Opons menu. Supported rates are 300, 600,
1200, 2400, 4800, 9600, and 19.2k baud. There must be 8 data bits, no parity, and 1 stop bit. To support the
mul-drop RS232 opon each unit is assigned a communicaons address which is set using the Com Address
item on the System Opons menu. All the commands have the following format:
@123XYZ<CR> The @ symbol iniates the command, all commands must begin with this symbol. The number
123 is the address of the Model 4215-HS which should respond to this command. This MUST be 3 digits so
type 001 for unit one, and 026 for unit twenty-six. The command itself will be a sequence of leers such as the
XYZ shown above. If the command requires a number as one of its parameters the number must be followed
by the pound sign “#”. Numbers that are less than one should include a leading zero so you should type 0.123#
to enter one-hundred twenty three thousandths. Commands are not processed unl a carriage return <CR> is
sent.
No Model 4215-HS will respond to address 000. All Model 4215-HS’s will respond to address 255. Throughout
the rest of this secon we will assume that you are using address 123. Whenever an Model 4215-HS executes a
remote command it will issue an acknowledge that includes the address and any required data.
