User Calibration
In case of severe overload the scale may loses its accuracy. Re-
calibration of the scale may be needed. The load cell of this precision
scale is normally protected against overloaded weight applied slowly, but
extreme overload caused by dropping the scale or dropping something
heavy on the scale may require re-calibration.
CAUTION: Please do not attempt any calibration by yourself unless you
have a 5lb weight available.
Make sure the scale is connected to the PC via USB cable or to AC
mains. Press the ON/TARE key and hold it for about 5 seconds. When
the display changes to , release the ON/TARE key. Now the
scale is in user calibration mode (the LCD also displays 5lb on the left
corner). Put 5lb weight on the platform. After the weight is stable, scale
will calibrate itself. Once the calibration is completed, scale will enter the
normal weighing mode.
