Explanation of Analog Measurement Channels
The internal voltmeter of the PTC-01 is a 16-bit A/D converter with a range of 25mV -20V. The resolution is
therefore approximately 0.3mV per step.
The ADC is multiplexed to 4 analog input channels (AIN1 – AIN4) Their function is described below:
All 4 channels are over-voltage and short-circuit protected
