Frequency filter:
Selectable filter from drop down menu. Select a frequency whose range is
between the Fundamental Frequency and the Switching Frequency but closer to
the fundamental. In this test we have set the inverter to a fundamental
frequency of 65Hz so we will select a frequency filter of 250Hz
Note: Do not select a filter too close to the fundamental frequency this may
result in the frequency measurement reading 0Hz
