AMETEK 2003RP - Manual (Page 117)

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?
