11.4 Making Measurements
The source has the capability to return current, peak current, crest factor, true power,
apparent power, power factor and voltage measurements.
Voltage Measurement
To measure the RMS voltage, use:
OUTP 1 /* Close output relay if it was not closed already.
MEAS:VOLT?
Current Measurements
To measure the RMS current, use:
MEAS:CURR?
To measure the peak current, use:
MEAS:CURR:AMPL:RES /* resets track and hold for peak curr. meas.
/* It may be need to turn the output on or program
/* as specific voltage at this time before taking a
/* peak current reading.
MEAS:CURR:AMPL:MAX? /* retrieves peak current reading.
To measure the current crest factor, use:
MEAS:CURR:CRES?
Power Measurements
To measure the true power, use:
MEAS:POW:REAL?
To measure the apparent power, use:
MEAS:POW:APP?
To measure the power factor, use:
MEAS:POW:PFAC?
