8.4 Measurement Commands
Measurement commands are typically queries only and return power source measurement
data values. This section is broken down into the commands for each measurement
parameter.
The following measurement commands are supported.
8.4.1 Voltage Measurement Commands
Query Format MEASure:VOLTage[:ACDC]#?
Description Returns the measured RMS voltage for the selected phase #. If no
phase number is specified, returns the reading for the last selected
phase.
Returned Data Format <nr2>
Query Example MEAS:VOLT:ACDC2?
230.0000
Query Format MEASure:VOLTage:DC#?
Description Returns the measured DC voltage for the selected phase #. If no phase
number is specified, returns the reading for the last selected phase.
Returned Data Format <nr2>
Query Example MEAS:VOLT:DC1?
2.2500
Query Format MEASure:VOLTage:AC#?
Description Returns the measured RMS voltage for the selected phase #. If no
phase number is specified, returns the reading for the last selected
phase. This command is equivalent to “MEASure:VOLTage[:ACDC]#?”
and is provided for backward compatibility with the UPC controllers.
Returned Data Format <nr2>
Query Example MEAS:VOLT:AC3?
230.0000
Query Format MEASure:VLL#?
Description Returns the measured RMS Line-to-Line voltage
1
for the selected phase
#. If no phase number is specified, returns the reading for the last
selected phase. Phase reference applies as follows:
# = 1 V
AB
, # = 2 V
AC
, # =3 V
BC
Returned Data Format
Query Example MEAS:VLL2?
398.3780
Note 1:
Line to Line voltage measurements are calculated based on VLN and phase angles and are
valid only for sinusoidal voltage waveforms with low levels of distortion and under balanced three
phase load conditions.
