Real Time Voltage Chart
The Real Time Voltage Chart feature allows the user to monitor in real time the last 60
seconds of the source voltage value and load voltage. The Voltage Chart freezes the last
30 seconds of the voltage profile and displays the current values.

Harmonic Analysis
The input signal is sampled at 64 samples per cycle, giving an overall sampling rate of
3840 samples per second for a 60 Hz system. This provides the ability to reproduce signals
of up to 1920 Hz. Therefore, up to the 31st harmonic can be calculated using discrete
Fourier transform with a fundamental frequency of 60 Hz. The fundamental for both the
Voltage and Current channels is calculated every sample meaning, every 260.41 μs. These
