Inputs

The Inputs menu provides conﬁguration options for all physical signal inputs of

the pow

er analyzer. Use this menu and the submenus to conﬁgure all wiring and

group settings. For normal operation, with the exception of the shunt selection, it

is not necessary to change these settings from the default values.

Wiring

For mu

ltiphase measurements, a number of c hannels can be assigned to a group

allowing precise frequency and phase analysis of the multiphase signals. The

frequency of the ﬁrst channel in the group is used as the fundamental frequency

for all channels in the group, and all phase measurements are relative to the phase

reference (voltage by default) of the ﬁrst channel in the group.

Below are ﬁgures showing how each channel would be connected for each

different wiring mode.
