Please read and follow all the instructions before using the unit. Calibration, inspections, and
maintenance shall be performed by professionals
Make sure the indicator is on a stable surface.
DO NOT disassemble or modify unit.
DO NOT exceed the rated load limit of the unit.
DO NOT use this product if there are any signs of damage.
DO NOT use for purposes other than weighing.
Keep other electronic equipment away from the unit.
Electrical Safety
Unit must be connected to a GFCI outlet.
Disconnect power before servicing unit.
All operators MUST discharge themselves before servicing unit.
Always pull the plug – not the cord – when disconnecting from the outlet.
DO NOT use if the power cord is worn or damaged
Power cord should only be replaced by certified service technicians using the original parts
SAFETY PRECAUTIONS
PREPARATION & SET UP
If the indicator is powered with an adapter, plug the adapter directly into the “DC” pin located at
the bottom of the indicator.
Always use a wall outlet to avoid interference from other wires
Turn on the indicator when there is no load
Calibrate before weighing when the scale is initially installed or moved to a new location

AC Adapter
If the indicator is powered with an adapter, plug the adapter directly into the “DC” pin located at
the bottom of the indicator. It is recommended to plug into a wall outlet to avoid interference with
wirings.
Battery
If you have an indicator with the rechargeable battery option, please charge the internal battery
fully before first time use. A 110 to 220V AC adapter should be provided with your indicator. Please
use only the AC adapter provided. To keep the battery in the best condition, fully discharge the
battery every month by leaving the indicator on until the indicator powers off, and then recharge
fully. If the battery will not be used for long time, please remove it to avoid leakage.

LIGHT INDICATION AND KEYPAD
FRONT VIEW
1. LIGHT INDICATION
lb: ON when the weight unit is pound [lb]
kg: ON when the weight unit is kilogram [kg]
g: ON when the weight unit is gram [g]
oz: ON when the weight unit is oz [oz]
Batt: GREEN when the battery is fully charged; RED when it is low
GROSS: ON when the current weight is the GROSS weight
NET: ON when the current weight is the NET weight
ZERO: ON when the current weight is 0 lb (0 kg)
HOLD: ON when the weight value is being held
UNDER: ON when the weight is below the min preset value
ACCEPT: ON when the weight is within the acceptable range
OVER: ON when the weight is over the max preset value
2. KEYPAD
ON/OFF Power on or off (Press hard and hold for 2 seconds)
Weight value hold (5 Hold options; can be changed in parameter settings)
HOLD

1. Resets the scale to zero when there is something on the scale (ex. Tare out the weight
of a pallet to weigh only the items on it)
2. Clears tare weight for gross weight

Power On
Turn on the power by pressing the power button for 2 seconds. Once it is on, the unit begins to
auto-check and count down from 0-9 before entering the weighing mode
Note: Anything on the scale before powering on will automatically be tared out.
Zero
Zero is only used when the scale is supposed to be empty
Pressing the ZERO key will reset your scale to 0
Depending on what your manual zero range parameter is set to, you can zero out any number
within the range, after that you will receive an error and will need to tare out the weight
Unit Selection
To switch between measuring units (lb/kg or lb/kg/g/oz/lb:oz ) press the UNITS key
Tare Function
Tare is used when you only wish to see the current change in weight, not the total weight
When the indicator is in gross mode (gross light is shown) pressing the TARE key will Tare the
current weight on the scale and enter the net mode (net light shown)
For example, add a container to the scale, press tare and the display
will show the tare symbol and reset back to 0. Now add the product to the container, it will only
display the weight of the product, not the container.
To exit Tare mode, press the TARE key again to enter gross mode and you will see the total
weight of the container and the product
BOTTOM VIEW
LOAD CELL: Port for connecting the scale.
RS-232 PORT: Serial interface port. (printer, second display, PC, etc.)
DC POWER: Port for DC power. (DC 9V adapter available)

Note: If you remove the container, the scale will display weight less that of the container.

Hold
There are 3 different hold functions you can choose from in the C11 parameter
1. Peak Hold: Grabs the highest weight (for materials testing, ie. tension and pulling force)
Press the HOLD key then add weight to the scale
The indicator will show the highest weight it recorded and hold it on the screen until a higher
weight is placed on the scale
2. Manual Hold: Grabs the current weight and holds it so it will not change/fluctuate
While weighing, press HOLD and the indicator will hold the current weight on the screen until
HOLD is pressed again
3. Average Hold: Used for weighing animal, the indicator will display the average weight sampled
from 3 seconds
Add livestock to scale and press HOLD
Indicator screen will show “LOC” for 3 seconds, then display the average weight from those
3 seconds
Press HOLD again to exit holding mode
Print
If the indicator is connected to a printer and the weight on the scale is stable press the PRINT
key to print the current weight

1. Turn on the scale by holding ON/OFF for 2 seconds.
2. Press HOLD and PRINT together to access the setup menu.
3. If done correctly, the display should now show C01.
4. Press PRINT to access the C1 channel. The display should show
5. Press ZERO to choose which unit you want to calibrate in (1 = kg, 2 = lb).
6. Press PRINT to set the value. The display will now show C02.
7. Press PRINT to access the C2 channel. The display should show
8. Press ZERO
to change the setting to the decimal places desired (The C2 channel is
used to adjust the decimal point on the scale. A value of 1 means there is one digit
behind the decimal point.)
9. Press PRINT to set the value. The display will now show C03.
10. Press PRINT to access the C3 channel. The display should show
11. Press ZERO to cycle through the values until the desired graduation appears.
(The C3 channel adjusts the divisions on the scale. A value of 1 selected and C2 set
to 1, the scale will read in 0.1 lb. increments.)
12. Press PRINT to set the value. The display will now show C04.
13. Press PRINT to access the C4 channel. The display will show
14. Enter in the maximum capacity you want to use for this scale by using UNITS
cursor right, and TARE and ZERO to move the values down and up. (The C4 channel is
to move the
used to enter in the max capacity of the scale; Make sure this doesn’t exceed the max capacity
of the scale; Max capacity divided by the increment set in C02 and C03 above cannot
exceed 5000.)
17. The C5 channel calibrates zero on the scale. Make sure the scale is empty.
18. Press ZERO to change the value to 1.
19. Press PRINT . The display will count down from 10-1 while the scale is calibrating zero.
When the display shows 0 the zero calibration is complete.
The indicator offers 2 calibration methods, Single Point which uses one weight
to calibrate or Linear Calibration, which uses multiple (2-7) weights for a more
accurate calibration.
To Calibrate using only 1 calibration weight (Single Point Calibration)
