DESCRIPTION
This value is the true rms output voltage measured at the voltage
sense lines.
This value is the true rms output current drawn by the load.
The output frequency is measured at the sense lines.
This value is the real power.
This value is the apparent power.
This readout shows the power factor of the load.
This readout reflects the highest peak current value detected at the
output. This is a track and hold peak current measurement. To
measure inrush current for a unit under test, open the output relay
and reset the peak current value using the BACK key. Then program
the output voltage and frequency and turn on the output relay. The
peak current measurement will continuously track the maximum
current value detected until reset. See also PEAK CURRENT in
