Voltage Measurements Screen
The Voltage Measurements screen displays the voltage
presently on any one of the input phases (AC N and AC BP)
and each phase of the load, as well as the differential
voltage as measured between any two phases of the inputs
and the load. See Figure 3-9.
3.4.5
Frequency Measurements Screen
The Frequency Measurements screen displays the
frequency presently on any one of the input lines (AC N and
AC BP) and the load. See Figure 3-10.
3.4.6
Ratios Screen
The Ratios screen displays the crest factor for each phase,
the present percentage of load for each phase and for the
total unit. Additionally, the load in KVA/KW is provided. See
Figure 3-11.
