with the RMS voltage in the denominator. Note that some definitions
of THD use the fundamental component (H1) of the voltage as the

denominator.
The controller can
component as the denominator. This mode can only be programme
over the bus by sending the “MEAS:THD:MODE FUND” command
or using the LxGui program. At power up or after a reset command,
the mode will revert back to RMS.
CURR THD
This readout displays the total current distortion for the selected
phase. The distortion calculation is based on the H2 through H50
over the bus by sending the “MEAS:THD:MODE FUND” command
or using the LxGui program. At power up or after a reset command,
with the RMS current in the denominator. Note that some definitions
of THD use the fundamental component (H1) of the current as the
denominator.
The controller can be programmed to use the fundamental
component as the denominator. This mode can only be programmed
the mode will revert back to RMS.
PEAK CURR
This readout reflects the peak current value detected at the output.
To measure inrush current for a unit under test, open the output
relay and reset the peak current value using the PEAK CURR
RESET entry. 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.
PHASE
Relative voltage phase angle measurement with respect to phase A.
Update Program Functions from Measurement Screen
The Shuttle can be used to update voltage or frequency settings from the measurement screen.
(Voltage adjustment or Frequency adjustment) depends on the last

The function of the shuttle
selection in the SET screen. If the cursor is on the top line (Voltage), turning the shuttle while i
the measurement screen will change the voltage. If the cursor is on the bottom line (Frequency)
turning the shuttle while in the measurement screen will change the frequency.
