the filters for this values! For the same reason this values can also be much bigger than the
values which can be derived from the harmonics (depending on the signal).
8.4.1 Default
With Default you see the most important values of the instrument. The available settings are
described in „5.4 Display of values“.
8.4.2 Voltage
With Voltage you see the harmonic values of the measured voltage and in the second row the
phase of the harmonic component.
With the softkey Chns you can choose the channel.
With the softkey Href you can select the reference signal (voltage, current or none). The
fundamental of this signal is always set to 0°. When selected ‘none’, the time window is the
reference.
With the softkey Link the harmonics of the linked values will be shown.
Using the rotary knob you can scroll through the list to see all harmonics.
8.4.3 Current
With Current you see the harmonic values of the measured current and in the second row the
phase of the harmonic component.
With the softkey Chns you can choose the channel.
With the softkey Href you can select the reference signal (voltage, current or none). The
fundamental of this signal is always set to 0°. When selected ‘none’, the time window is the
reference.
With the softkey Link the harmonics of the linked values will be shown.
Using the rotary knob you can scroll through the list to see all harmonics.
8.4.4 Power
With Power you see the harmonic values of the measured powers. The synchronisation
frequency is shown in the first row, displaying all channels.
With the softkey Chns you can choose the channel.
