displays CHECK(SET 00), and press G/N/SET again, the screen show MPC, version, date
and offset value.
2) Under the offset showing screen, press each button to check if they word according to
following tips: Use numeric buttons to show NUM*, Use SMPL to show SMPL, Press
G/N/SET to make green light(GN) on, Press G/N and backlight on(UWS), press
+PRINT/HI and red light(Hi) on, Press MR to show MR, Press TARE to show TARE, and
press M+/SAVE to show MP, Press -PRINT/LO and make orange light (LO) on. Press
ZERO/ESC to return SET 00 screen and CHECK flashes.
Press key ZERO/ESC any time to go back to weighing mode
About offset value:
The offset value of no load condition should be higher than 10000, and lower 700,000 in full
load condition.

JADEVER SCALE CO., LTD - www.dongminhphat.com
14 JCL Service Manual - www.cantudong,com
Preliminary checks when the offset value is out of the normal range:
1) Is the scale is placed at a flat and stable surface?
2) Is there an overload situation?
3) Is the shipping protection screw removed?
4) Is there anything under the weighing pan?
5) Is the battery electricity capacity ok?
6) Please refer to 2-2 to see if the fault is due the power circuit failure.
Compensation method
: If the offset value is too high, please install a Resistor between S+ and E-. The higher
resistance, the lower the offset value becomes.
