SAFETY PRECAUTIONS
For safe operation of the weighing indicator, please follow these
instructions:
●Calibration inspection and maintenance of the indicator are prohibited by non-pro-
fessional 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 inuence 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
rst 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 indicator while there is no load
●Calibration may be required before weighing when the scale is initially installed or
moved from a location

POWER SUPPLY
AC Adapter
Please use the included adapter to charge your indicator. We recommend to plug into a
wall outlet to avoid interference with other wirings.
Adapter
1. Connect adapter to indicator and plug into wall outlet
2. If adapter light is red, indicator needs to be charged
3. When indicator is completely charged, adapter light
will turn green
4. Turn indicator on
5. An empty battery icon will ash for a couple
seconds on indicator
6. This does NOT mean indicator is not charged
7. Indicator charge lasts up to 22 hours
Battery
Please charge the internal battery fully before rst time use. A 110 to 220V AC adapter
should be provided with your indicator. Please use only the AC adapter provided to pre-
vent damage to your indicator. To keep the battery in 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 is not going to be used for a long period of time it is recom-
mended to remove it to avoid leakage.

DISPLAY AND KEY DESCRIPTION
ON/OFF Powers the Indicator On or Off if held for 3 seconds
TOTAL 1. Accumulates weights
2. Works with SET key to perform the Accumulation function and check
the Accumulation result
UNIT Shifts between weighing units, KG and LB
ZERO 1. Zero’s the scale within zero range
2. Tare’s the weight if its over the zero range
SET 1. Long Press to print the weight
2. Combined with ON/OFF to enter into calibration
3. Combined with the TOTAL key to check the Accumulative sum
lb The weight is shown in pounds
kg The weight is shown in kilograms
hold Shows you are in Hold mode
Gross Shows you are in Gross weight mode (includes tare); default mode
Net Shows you are in Net weight mode (weight without tared weight)
Tare Display’s tare satus
The scale is stable
The scale is at zero
Hi Flashes when weight is higher than set alarm parameter
Low Flashes when weight is lower than set alarm parameter
Ok Flashes when weight is within the set alarm parameters

OPERATING INSTRUCTIONS
Power On
●Turn on the power by pressing the power button for 3 seconds. Once on, the scale
will ash 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
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 ZERO 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 ZERO 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
Unit Selection
●To switch between measuring units (kg/lb) press the UNIT key
7
Accumulation
●The Accumulation function is used to add multiple weights and total them together
● In weighing mode load the rst weight, once stable press the TOTAL key to enter
the Accumulation mode. The screen will show “n001” followed by the weight.
● Remove the weight so scale reads 0 before adding the second weight to the scale
●Once the second weight is stable press TOTAL key to add the weight to the Accumulat-
ed total, the screen will show “n002” followed by the weight.
●Repeat previous steps until all desired weights have been added to the total (max 999
times)
●When you are done and want to display the Accumulated total, press the TOTAL and
SET key together. The Accumulated number “n###” (the number of weights you
are adding together) will ash on the display followed by the total
● The total will display by ashing between 2 sets of numbers
● There are 8 digits in total, the display will ash 4 at a time, the rst 4 on the left and
the last 4 on the right. For example if the rst 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 SET 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 TOTAL 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 Accumulated total, then use the arrow key to
change to “CLr y”.
● Finally, press the SET key to select exit Accumulation mode

Hold
To use the hold feature press the SET and ZERO keys at the same time. Press both again
to release the 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 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/uctuate
● 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 (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 the scale
is stable
4. Average Hold: Used for animal weighing, 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 your pallet jack has a printer and the weight on the scale is stable press the SET key
for 1 second to print the current weight
Note: In tare mode the printer can not print if negative weight is shown
Print Out Format:
NO. 003 (S/N)
net 6.00kg (Net weight)
tare 2.88kg (Tare weight)
gross 8.88kg (Gross weight)
