When the scale is ON, simultaneously press and hold down TARE and ZERO buttons for more than 5 seconds till the
“A.oFF.x” is displayed (x=0,1…9: means when the scale has no weight changing and no key pressed for 1…9 minutes, the
scale will auto power off to save battery power, when x=0, means that the auto-power off function is disabled). Press the
TARE button to choose the auto-off time and press ZERO button to con rm and save the setting.
Some display symbol meaning:
Power-on zero-point is over (calibration zero-point) +20%FS) when scale is turned on, or the reading weight is over (power-
on zero-point) +5%FS when pressing ZERO button;
Power-on zero-point is below (calibration zero-point) -20%FS) when scale is turned on, or the reading weight is + (power-on
zero-point) -5%FS when pressing ZERO button;
the current weight is less than –25% FS;
the current weight is over 102% FS;
Zero point at calibration;
Full capacity at calibration;
EEPROM accessing error or data in EEPROM is error or not in their normal range;
The voltage of internal working is below 5.7V(
The voltage of internal working is x.xV(
