ASSEMBLING
Unpack the package, put the platter on the top of the loader.
Put the balance on a steady flat surface away from vibration, direct sunshine, air
blow or strong magnetic disturbance.
Battery locker is at the bottom of the balance, switch the locker to to turn on the
balance, please switch the locker to during moving or transportation
TURN ON THE BALANCE
Connect the balance to power supply.
Press function key ON/OFF to turn on the balance, the balance will in turns display
following figures,
8.8.8.8.8.8.
Battery Voltage U=
Maximum capacity
-----------Finally, the balance stays in a standby state, showing 0.00g on the display
Notice: the lasting time of --------- will be decided by the stability of the loadcell, thus, the
balance must not be located on an unstable surface or near windows or air flow. If symbol
flashes in the display, it means the balance is not in a stable condition, calibration and
counting operations is not allowed.
CALIBRATION
The purpose for this operation is to calibrate the balance, to achieve the best
performance in case there is obvious tolerance error in weighing or the balance is
located in different gravity due to different latitude.
it is suggested to warm up the balance over half an hour before calibration.
Remove all loads from the platter, press function key TARE to clear the readings
to 0.00g.
Press and hold function key CAL for 3 seconds, release function key CAL when “---
CAL---“ is shown in the display, a figure of standard weight will flash in the display,
put a standard weight on the platter accordingly, standby state “------“ will be shown in
the display for a few seconds before the standard weight figure is shown in the
display, remove the weight, “------“ standby state will remain for a few seconds before
the balance enter stable weighing mode, showing 0.00g.
It is recommended to make the operations twice to achieve the best calibration
result.

WEIGHING
When the balance is warmed up and calibrated, 0.00g is shown in the display indicating
weighing mode, put the object on the plate. Wait for the stability, the weight of the object is
shown in the display.
TARE
When a loader is put over the plate, its weight is shown in the display, press function key
TARE, 0.00g will be shown in the display, indicating the weight of the loader is deducted.
Put the object into the loader, when stable, the figure shown in the display is the weight of
the object.
PIECE COUNTING
Remove all loads from the plate, press function key TARE to clear the readings in the
display, press function key PCS to enter counting mode, figure 10(default sampling
quantity) will be shown in the display, weighing unit changes from g to pcs.
Put 10 samples on the plate, press function key PCS, the balance will show “-----“ before it
shows 10 pcs in the display, the balance enters counting mode.
Notice: In counting mode, the weight of the sampling objects should be even, the weight
of the individual sample should not be less than the division of the balance.
Return to Weighing Mode: Press function key PCS to return to Weighing mode.
Unit Conversion
Press function key UNIT to change from weighing unit ct/oz/lb/g, default weighing unit is
set to g.
POWER SAVING MODE
Press and hold function key PCS for 3 seconds, OFF will appear in display, press function
key PCS once, ON will appear in display, press function key PCS again, 0.00g will show
in the display, the balance enters power saving mode, the balance will enter standby state
in 10 seconds.
Make the same operation to exit power saving

CHARGE THE BALANCE
OVERLOAD
The weight of the objective cannot exceed the rated maximum capacity of the balance,
when exceeding, “-------“ will be shown in the display, remove the objective immediately
from the platter so as to prevent damages to the balance.
TIPS
Warming up is necessary before any operation to the balance.
In TARE mode, the value of the tare cannot exceed the maximum capacity of the
balance
Calibration is necessary to ensure a reliable weighing.
Switch off the balance when it is not used.
It is suggested to charge the battery every 3 months when it is not in regular use.
