    5. SETUP 5-1. Calibration Calibration is the process of adjusting weight balance between "Real Weight" on the Load Cell and "Displayed weight of Indicator". When you replace Load Cell or Indicator, you have to do Calibration process once again. Before start to the calibration mode, Please turn on the indicator and preheat about 15 min.
