8. HARMONICS
The control unit performs a calculation of the different voltage and current
harmonics. The information shown is:
• Spectrum graphic in frequencies.
• Values in % of the harmonic components up to 20.
• Total harmonic distortion (THD) and total harmonic distortion plus
noise (THDN) in %.
Using the arrow keys •▼the signal to be analysed is selected (VG1, VG2, VG3,
VR1, VR2, VR3, I1, I2 or I3). To display the harmonic press the key ü.
