3.2.7 Voltage Measurements Display
From the Voltage Measurements display we can see the voltage currently 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.
Pressing Soft Key #1 results in the Frequency Measurements display. See Figure 3-10.
Figure 3-9: Voltage Measurements.
3.2.8 Frequency Measurements Display
From the Frequency Measurements display we can see the frequency currently on any one of the input lines (AC
N and AC BP) and the frequency of the power being supplied to the load. See Figure 3-10.
Pressing Soft Key #1 results in the Ratios display. See Figure 3-11.
