The Dual Voltmeter module provides the ability to display the voltage of an input, both the instantaneous value or a DC or AC average value. Each of the two sections is identical in features and behaviour.
In instantaneous mode, the measurement is made every 50ms; in DC mode, the meter measures the average of the CV voltage it receives during the measurement period (set by the measurement frequency control); and in AC mode, the meter measures half the peak-to-peak value (again over the measurement period), which is half the deference between the highest voltage and the lowest voltage it receives.
