Changing the display
22
The mains monitor's display mode can be changed at the A 3000 HV power
amplifier connected to it, or at the P 3000 HV pre-amplifier.
Changing the display mode via the P 3000 HV:
The measurement mode can be changed via the P 3000 HV's configuration
menu. You will find detailed information on using this menu in the operating
instructions for the P 3000 HV (see Chapter 'Basic settings of the
P 3000 HV').

If you are using two PS 3000 HV in mono mode, any change you make to the
display mode using the P 3000 HV affects both PS 3000 HV simultaneously.
Changing the display mode via the A 3000 HV:
A long press on the A 3000 HV's  button cycles the display mode through to
the next option.

If you are using two A 3000 HV with two PS 3000 HV, a change in display mode
only affects the PS 3000 HV connected directly to the A 3000 HV. This makes it
possible to select different settings on both PS 3000 HV, in order, for example,
to be able to monitor voltage and interference simultaneously.
