7.4.3 Sensor calibration
Sensor calibration adjusts the weight measurement of the detector unit. The calibration
consists of three steps as follows.
• ADC zero calibration
• ADC offset calibration
• ADC span calibration
For the ADC offset weight calibration, either 0 g or an offset weight (0 to 100 g) can be used.
Using an offset weight other than 0 g is recommended for density measurement.
