! Connection between load cell and indicator must be reliable, shield wire must be connected
to ground reliably. Connection or disconnection are not allowed when the indicator is on, which
may damage the indicator or load cells.
! Static protection must be properly adopted as the load cell and indicator are all static sensitive
equipments. Welding or other strong electricity operation should be strictly forbidden. During
thunderstorm season, proper lightening protection should be tanken care of to protect the load
cells and indicators from damaging by lightening and to ensure the personal safety and the safely
running of the weighing and related equipments.

3.0 OPERASYON
3.1 CİHAZ AÇMA/KAPATMA VE OTOMATİK SIFIRLAMA
The indicator power can be controlled by the on-off key on the front faceplate . The indicator
will perform self-check after turned on. If the scale was found departure from the calibrate zero
however still within the range of turn on auto zero then the indicator will display “0” and the in
dicator light for “zero digit” will be on. If the scale was found departure from the calibrate zero and
out of the range of turn on auto zero then the indicator will display the current read
If the range setting of the turn on zero is”- -“ wihch means zero of last turn off, then zero
operation will not be carried on and the zero of last turn off will be automatically readin and the
current weight will be displayed.
3.2 ELLE SIFIRLAMA
Indıcator will back to zero when pressing “ZERO” key if the gross weight is within the range
of manually zero and stable. Manually zero is not valid under the “NET” displaying mode;
3.3 DARA ALMA
TARE operation can be carried out if both gross weight and net weight are above zero and
stable.
The indicator will display ”0” after pressing the “TARE” key. The tared weight is current gross
weight. And the indicator will enter “NET” displaying mode and the “NET” indicator lights will be on;
The indicator will exit “NET” displaying mode after pressing “TARE” when the gross weight is
“0” and under “NET” displaying mode
3.4 TOPLAM ALMA, TOPLAMI GÖSTERME VE TOPLAMI TEMİZLEME
1. In case, the net weight is bigger than the minimum measurable value (5 divison) and stable,
When pressing “TOTAL”, the current net weight will be added and the “TOTAL” indicator light will be
on and total value will be displayed , which will be changed to adding times [n ***]
After 3 seconds and exit the total displaying status after another 3 seconds. Next operation will be
only valid when the net weight is smaller than the minimum measurable value.
2. If keep pressing “TOTAL” until buzzer alarms under the weighing status “FUNCTION” and “TOTAL”
lights will be on and you can check the total value by pressing “” to see the adding times and again
“” to exit.
3. If you press ““ after keep pressing “ TOTAL” and enter the total displaying status there will be an
notice [CLRAr-] which means to clear the total value or not. Press ““ to clear and “FUNCTION” to
exit and keep the value.

OPERATION DIAGRAM
4.0 CALIBRATION
After self checking of turn on, it will enter normal weighing display, warm up for 15-30
minutes, open the calibration cover in the back side of the indicator; touch the calibration switch to
enter calibration status, the detailed steps as below:

Press ”” the flash digit will move towards right
Press ”” to increase the number of flash digit
Press “” to confirm and enter next step.
For example: 3000
4 After stable, press to
confirm
【noLoAd】 Zero calibration: Make sure indicator under no-load
status, press “”after date stable to confirm Zero
5 Input the weight of
loading weights
【AdLoAd】
After display
for 2 seconds,
auto switch to
load input
【003.000】
Linearity Calibration:
Add the weights to the scale, input the value of the
weights in indicator, it is better to close to the full
capacity. Operation is same as full capacity setting.
5 seconds after the stable indicator light on
Press “” to confirm and finish the calibration
6 Return back to
weighing status
【 End 】
【 3.000】
After calibration, 2 second after display “End”, the
current weight will be displayed immediately.

‘B’: Read net weight, indicator back: NW:0013.45(kg)
‘C’: Read tare, indicator back: TW:0010.00(kg)
‘D’: Manually zero, indicator back: ‘D’
‘E’: Tare operation, indicator back: ‘E’
