5 Calibration - Using an External Calibration Weight:
Calibration is required when the weighing machine is initially installed or if the scale is moved to a
substantial distance from the original location. 10 minutes warm up of scale is always needed before
calibration.
Single segment calibration (recommended):
Turn the scale on and then turn it off.
Press and hold [ZERO] and then turn on the scale again
The LCD will show SCALE on first line, CAL-0 (flashing) on the second line and AD value on the
third line.
Press [SAMPLE/UNIT] to select calibration unit kg or lb.
After the stable A/D value is displayed, press [ZERO], after 2 or 3 seconds, the scale will show 0.
Key in calibration weight through numeric keypad and then place the corresponding calibration
weight on the weighing pan. ( At least 50% or above of the capacity calibration weight is
suggested to get an accurate calibration)
Press [ZERO] to confirm once the scale is stable and stable indicator shows on display.
Press [ZERO] key, the second line of display will show 00000 and now calibration is finished.
Turn off the power, then turn on the power again, place a known weight on the platform to verify if
it is accurate.
