Measurements with up to
8 power channels
The following block diagram
applies wiring A:1+2+3 B:4 and
is typical for a low power speed
8 channel measuring at uninterruptible power supply with intermediate DC link
variable drive. This example is
used to explain the settings
and displays of the LMG500.
