Press
MSV
to display the spectral level (curve) and RMS values at the
configured MSV1 and MSV2 frequencies (see § 3.4.1)
Press to stretch or shrink the scale of the bargraph
Press
to view interharmonics when the display filter concerns only one
phase (L1, L2, L3, or N)
Press
with the
MSV
function active to view the limits profile for the
level of V or U according to the configured frequency (see § 3.4.1)
The channel numbers are saturation indicators. The circle’s interior will be
colored when the measured channel is full or at least one channel used to
calculate it is full.
To move the harmonic order’s cursor, use the ◄ ► buttons
If there are more harmonics when you reach the last harmonic of the screen,
you will go to the second screen.
To change the display filter, use the ▲ ▼ buttons. The available display
filters depend on the chosen distribution network and connection type
The calculation of the harmonics starts when the instrument turns on.
To reset the values, press the button.
