Measurement of Harmonics
Voltage
Range
DC – 25h
26h – 33h
34h – 49h
The voltage harmonics will be null under the following threshold:
- DC: if <1V or <2% of 1st harmonic
- 1st harmonic: if <2V
- 2nd to 49th: if <1V or <2% 1st harmonic
Current
Range
DC – 25h
26h – 33h
34h – 49h
The current harmonics will be null under the following threshold:
- DC: if <2% of 1st harmonic or < 0.2% of clamp full scale
- 1st harmonic: if < 0.2% of clamp full scale
- 2nd to 49th: if <2% 1st harmonic or < 0.2% of clamp full scale
Setting the FLEX option the DC component will be ignored.
