4.3.1 DC Bias Calibration

For DC Bias calibration, use CONTROL_Burst_Cal_DcBias(0); the default GUI settings must not be changed for this burst. The system does not create any output waveform for this calibration procedure. The ULC1001 determines the DC offset between the internal ADC mid-code and the measured current and voltage values with no signal input.

The remaining calibration bursts, (1-3, 5), are used to setup cleaning modes and the temperature, mass detection, and power algorithms.
