SAFETY PRECAUTIONS
For safe operation of the weighing indicator, please follow these instructions:
● Calibration inspection and maintenance of the indicator are prohibited by non-
professional staff
● Please ensure that the indicator rests on a stable surface
● The indicator is a piece of static sensitive equipment; Please cut off power during
electrical connections
● Touching the internal components by hand is prohibited
● DO NOT exceed the rated load limit of the unit
● DO NOT step on the unit
● DO NOT jump on the scale
● DO NOT use this product if any of the components are cracked
● DO NOT use for purposes other then weight taking
● To avoid damaging the battery do not keep charger plugged in once battery is fully
charged
● Make sure the weight is not over the Max capacity as it could damage the load cell
inside
● Material that has a static electric charge could influence the weighing. Discharge the
static electricity of the samples, if possible. Another solution to the problem is to
wipe both sides of the pan and the top of the case with an anti-static agent
Please take anti-static prevention measures
Any accumulated charge on the body of the human operator should be discharged first
before opening the protective container with ESDS devices inside. The discharge can
be accomplished by:
● Putting a hand on a grounded surface or, ideally, by wearing a grounded Anti-static
Wrist Strap and an Anti-static Mat
PREPARATION & SET UP
● Plug into a wall outlet to avoid interference with other wirings
● Turn on the balance while there is no load
● We suggest to warm-up the balance by powering on 5 minutes before use for
accurate weighing
● Calibration may be required before weighing when the balance is initially installed
or moved from a location

POWER SUPPLY
● The indicator uses 3 AAA batteries which will work for about 30 hours with the
backlight turned on, if you turn off the backlight the battery can last up to 100
hours
● This low battery icon will display when the indicator detects low battery, if not
replaced in time the indicator will power off automatically
● If you are using the included DC power supply, the indicator will not use battery
power
● Plug the adapter directly into the “DC” pin located at the back of the indicator. We
recommend to plug into a wall outlet to avoid interference with other wirings

OPERATING INSTRUCTIONS
Powering On or Off
● Press ON/OFF key for 1 second to power on. Machine will self inspect and count
from 1 - 9 before entering weighing mode and displaying 0
● Press ON/OFF key for 1 second to power off
● Indicator will auto power off when it has low battery
● Auto power-off in 10/20/60 minutes with no operation can be set in the parameters
Zero/Tare
● The zero function is used only when the scale is empty and is not at gross zero due
to material build up
● If the weight on the scale is within the zero range (2% of the max. capacity) and
stable and ZERO is pressed, the indicator will zero the scale and stay in gross
weighing mode
● 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
● If the scale is out of the zero range (above 2% of the max. capacity) and stable
the indicator will Tare the scale and go into Net weighing mode when ZERO is
pressed
Print
● To print press and hold the UNITS key when weighing is stable
● Communication Setting must be set to #2 for Print mode
Hold
There are five different hold functions, you can choose the best option for you and set it
the parameter settings
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

7
● While weighing, press HOLD and the indicator will hold the current weight on the screen
until HOLD is pressed again
3. Auto Hold: If the weight on the scale is above 20d 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 the scale is
stable
4. Average Hold: Used for animal weighing, the indicator will display the average
weight sampled from 1-9 seconds (Set in the HAt parameter setting)
● Add animal to scale and press HOLD
● Indicator screen will show “LOC” for 1-9 seconds, then display the average weight
from those seconds
● Press HOLD again to exit holding mode
5. Auto Average Hold: Used for animal weighing, the indicator will display the
average weight sampled from 1-9 seconds without the need to press the HOLD key.
If the weight on the scale is above 20d (scales division x 20) and is stable, the
indicator will start grabbing the average weight sampled from 1-9 seconds (Set in the
HAt: parameter setting). In parameter Hadt you can set a determined loading time
from 1-9 seconds. This is the time you have to load the animal before the scale
begins to take the average weight.
● Add animal to scale. Once weight is added to the scale, the scale will wait the set
loading time and then the Indicator screen will show “LOC” for 1-9 seconds
● It will then display the average weight from those 1-9 seconds for 3 seconds and
then repeat the process

CALIBRATION
To Enter Calibration Settings
● Turn indicator off. Then press and hold the HOLD and UNIT key simultaneously
while the indicator is turning on (Do this while indicator is counting down)
● The display will show [CAL kg], meaning the unit is kg
● Press UNIT if you want to change the unit to lb; Display will change to [CAL lb].
● Press HOLD to confirm your unit choice
● The display will most likely show [FS 5], meaning the max. capacity is 200kg, (see
tables below for other variances)
● Press UNIT to change the capacity range to your scales capacity Calibration chart

If FS = 6
Please follow the procedure below:
● The display will show [dP 1], to indicate how many decimal places you want; press
UNIT to change, and press HOLD to confirm (ex. DP 2 = ####.##)
● The display will show [d 2], to indicate the division; press UNIT to change, and
press HOLD to confirm
● The display will show [CAP ], to indicate the max. capacity; press HOLD to
display the current max. capacity; press ZERO to left shift and UNIT to change the

UNIT to change the calibration loading weight; Then press HOLD to confirm
● The display will show [CALon] please follow the steps for FS values of 0-6 to
complete calibration
For FS values of 0 - 6
Please follow the procedure below:
● The display will show [CALon], press HOLD to enter into weight calibraion, or
press ON/OFF to exit calibration
● The display will show [noLoAd] for zero calibration; make sure there is no load
on scale, then press HOLD to confirm and zero calibrate
● The display will show [AdLoAd] for loading calibration; place calibration weight as
defined by the tables above on the scale
● Once the weighing platform is stable, press HOLD to confirm and calibrate
● The display will show [CALEnd] when the calibration is complete, press HOLD to
save the weight calibration and press ON/OFF to exit and go back to weighing mode
