OPERATING INSTRUCTIONS
Power On
● Turn on the power by pressing the power button for 2 seconds. Once on, the scale will
flash the voltage and then begin to auto-check and count down from 0-9 sequentially
before entering the weighing mode
Note: Anything on the scale before powering on will automatically be tared out.
Zeroing
● The zero function is used only when the scale is empty and is not at gross zero due to
material build up
● 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 your set selection, after that you will receive an error and will need to tare
out the weight
Unit Selection
● To switch between measuring units ((kg/g/lb/oz/lb:oz) press the UNITS key
Tare Function
● The Tare function is used when you only wish to see the current change in weight, not the
entire amount of weight that is on the scale
● 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 if you are using a container add the container to the scale, press tare and the
display will show the tare symbol and reset back to 0
● Add your product to the scale to weigh without the weight of 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
Note: If you remove the container the scale will show the minus weight of the container
To use a pre-set tare weight
● Press and hold the TARE key for 2 seconds
● Input the tare weight using the arrow keys
● Press print key to confirm

Heavy Duty Pallet Digital Scale
Counting Function
● The counting function is used to count a high volume of identical parts. You can do this by
setting a sample and then either adding to the sample or taking away from the sample to
count the number of objects on the scale
● In weighing mode: Put a sample weight on the scale (Sample options are 5, 10, 20, 50,
100, 200, 500)
● Then press the COUNT key to go to the counting mode (“pcs” will light up)
● It will then display the sample number (ex. PCS 0) which you can change using the up
or down arrows
● Press the PRINT key to confirm your sample number
● The scale is now ready to start counting, load your product on the scale and the indicator
will show the quantity
● To exit counting mode press the COUNT key
● If you want to count a different product hold the PRINT and COUNT keytogether and the
sample pieces will reset back to zero
Accumulation
● The accumulation function is used to add multiple weights and total them together
● In weighing mode load the first weight, once stable press the ACCUM key to enter the
accumulation mode. The “total” indicator/light will display
● The screen will show “n001” to indicate the first weight has been saved
● Remove the first weight and press the ZERO key to stabilize thescale
● Add the second weight to the scale
● Once stable press the ACCUM key to add the weight to the accumulated total
● The screen will show “n002” to indicate the second weight has been saved
● Repeat previous steps until all desired weights have been added to thetotal (you can
accumulate up to 999 different weights)
● When you are done and want to display the accumulated total, press the ACCUM and
PRINT key together. The accumulated number “n002” (the number of weights you are
adding together) will flash on the display followed by the total
● The total will display by flashing between 2 sets of numbers
● There are 8 digits in total, the display will flash 4 at a time, the first 4 on the left and the
last 4 on the right. For example if the first 4 digits are “0012” and the last 4 digits are
“3456” the actual weight is 001234.56 or 1234.56 lbs/kg
● If you want to print the accumulated total, hold the PRINT key for one second while the
last 4 digits of the total are shown
● To exit accumulation mode, wait for the last 4 digits to the right of the screen to appear,
and then press and hold the ACCUM key for one second
● “CLr n” will be displayed, asking you if you want to keep the data?
● If NO you do not want to clear the accumulated total, then keep “CLr n”.
● If YES you do want to clear the total, then use the arrow key to change to “CLr y”
● Finally, press the PRINT key to select exit accumulation mode

Hold
There are 4 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 thescreen 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 onthe screen
until HOLD is pressed again
3. Auto Hold: If the weight on the scale is above 20d (20 x division) and is stable, the indicator
will hold that weight on the screen for 3 seconds then go back to general weighing
● Pressing the hold key is unnecessary, holding is done automatically when thescale is
stable
4. 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 averageweight 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 pressthe
PRINT key to print the current weight
● In accumulation mode hold the PRINT key for one second when the last 4 digits of the
total weight are shown to print the total weight
Note: In tare mode the printer cannot print if negative weight is shown

INDICATOR PARAMETER SETTINGS
The parameter settings menu has a calibration section (C01 to C07 explained above) and a
parameter settings section (C08 and up).
To access the calibration section the seal switch (located at one corner of the PCB) must be OFF.
This will allow access to all C01 and up settings. If the seal switch is ON, then only C08 and up
can be accessed by the user. If you break the official seal by opening the back of the indicator to
access the seal switch, you may need to have the indicator recertified. Be sure to adjust the seal
switch back to the original setting after calibration/configuration has been performed.
To enter calibration/parameter settings, follow the procedure below:
1. Make sure the unit is set to either kg or lb
2. Press and hold the HOLD and PRINT key at the same time for 2 seconds
3. Navigate through the settings (C01 to C45) as shown in the table 4 below by using the
