ENTRY 

DESCRIPTION 

measurement will continuously track the maximum current value detected until reset. 

See also PEAK CURRENT in MEASUREMENTS 2 screen. 

VOLT THD 

This readout displays the total voltage distortion for the selected phase. The distortion 

calculation is based on the H2 through H50 with the RMS voltage in the denominator. 

Note that some definitions of THD use the fundamental component (H1) of the voltage as 

the denominator.  

If desired, the user can program the power source controller to use the fundamental 

component as the denominator. This mode can only be programmed over the bus by 

sending the “MEAS:THD:MODE FUND” command.  At power up or after a reset command, 

the mode will revert back to RMS. 

PHASE 

Relative voltage phase angle measurement with respect to phase A. This readout is only 

relevant if an external clock source is used. 

 

Update Program Functions from Measurement Screen 

The Shuttle knob can be used to update voltage and/or frequency settings while the 

measurement readout screen is displayed.  To do so, select the desired parameter to be 

changed while in the SET screen using the left arrow cursor. Then, select the measurement 

screen by pressing the MEAS button. While the measurement screen is visible, the shuttle 

continues to operate.
