To measure and display the current harmonic, the instrument uses the following mea-
surements and waveforms:
●
"MG 6" to measure the power waveform
●
"MG 7" to measure the spectrum voltage
●
"MG 8" to measure the spectrum current
●
"M2" Math 2 to calculate the power
●
"M3" Math 3 to calculate the FFT of the voltage
●
"M4" Math 4 to calculate the FFT of the current
The used resources are listed in the "Details" tab. See also: Chapter 19.2.3, "Details
tab" , on page 1135.
The current harmonic results are defined as follows:
Result Table Bar Chart Match Description
Harmonic Index Value of the X-Axis The harmonic order
Frequency - The frequency value of the signal
Value Value of the Y-Axis. Shown
by a green bar The present value of the current harmonic
Maximum Shown by a darkened green
bar The maximum measured value
Standard limit Shown by a white bar The maxim allowed value according to the
selected standard
"Y max" "Y max" Sets the upper limit for the display of the Y
scale.
This value can be reset with the "Reset Max"
button
The following remote commands are used for handling the measurement results:
