Peak-to-peak
1. The amplitude of a waveform between its maximum
positive value and its maximum negative value
2. A measurement principle where the measurement
quantity is made by calculating the average from the
positive and negative peak values without including
the DC component. The peak-to-peak mode allows
considerable CT saturation without impairing the
performance of the operation.
Peak-to-peak with
A measurement principle similar to the peak-to-peak

mode but with the function starting on two conditions:
the peak-to-peak value is above the set start current or
the peak value is above two times the set start value
