MEASUREMENT 3
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 fundamental voltage (H1) in the denominator. Note that other
common definitions of THD use the RMS value of the voltage as the
denominator. This may result in different readings between
instruments depending on the implementation chosen. The mode used
by the power source is selectable over the bus.
CURR THD
This readout displays the total current distortion for the selected phase.
The distortion calculation is based on the H2 through H50 with the
fundamental current (H1) in the denominator. Note that other common
definitions of THD use the RMS value of the current as the
denominator. This may result in different readings between
instruments depending on the implementation chosen. The mode used
by the power source is selectable over the bus.
INST PK CURR
This readout reflects the instantaneous peak current value detected at
the output. This value is updated continuously and does not require a
reset operation like the PEAK CURR readout. The instantaneous peak
current does not use a track and hold mechanism like the PEAK
CURR measurement in the MEASUREMENT 2 screen. Instead, it
tracks the peak current on a cycle-by-cycle basis. The INST PK
CURR typically tracks the rms current and the crest factor.
Update Program Functions from Measurement Screen
The Shuttle can be used to update program parameters such as voltage, frequency or current from the
measurement screen. This can be achieved with the following sequence:
1.
Select the program 1 screen using the PROG key.
2.
Use the up and down key to select the desired function to update. (Selects parameter that will be
changed by the shuttle once in the MEAS1 screen)
3.
Select the measurement 1 screen by pressing the MEAS key.
4.
The pointer symbol (
) points to the programmed parameter (V, F or CL) that will be affected by
turning the shuttle.
