SECTION 10 CALIBRATION
Press UNIT key and M+ key together when normal weighing mode, display shows
“F0 H-L”, press TARE key until display shows “PrOG”, press ZERO key, display
shows “PIN”, You can press G/N、UNIT、ZERO key to enter setting mode, press
TARE key to select "p2 CAL", press ZERO key to sure. press TARE key to
select .While it is showing "CAL " press the ZERO key to enter. The display will
show "linear".
1. Normal calibrate
Press TARE key to select "nonlin".then press the ZERO key to enter,the display
shows: "unload
” Remove any weight from the platform. After stable indicator on,
press the ZERO key.
Then the display will show the last calibration weight used. If this is correct ,you can
