OCM-133C Power Calibrator
OUTP:REF:PULL (?) <CPD> { 0 | 1 }
This command connects the internal pull-up resistor (150 Ω) to the Energy pulse output.
 0 disconnects pull-up resistor
 1 connects pull-up resistor
If query is sent, calibrator returns 0 or 1.
Example: OUTP:REF:PULL 1 connects pull-up resistor
OUTP:REF:PULL? calibrator returns 0 or 1
OUTP:REF:CONS(?) <DNPD>
This command sets number of pulses per selected unit (pulses generated on Energy
pulse output on the rear panel BNC).
<DNPD>
Parameter represents the value number of pulses per selected unit.
If query is sent, calibrator returns set value using standard exponential format. Example:
400.0 i/kWh is returned as 4.000000e+002.
Example:
Number of pulses 1000 i/kVArh:
OUT:REF:CONS 1000.0
OUT:REF:UNIT VAR
OUTP:REF:UNIT(?) <CPD> { W | VA | VAR }
This command defines unit of constant for pulses generated on Energy pulse output.
<CPD>
If query is sent, calibrator returns selected unit.
Example: OUTP:REF:UNIT VAR <cr> - sets energy pulse output unit VAR
OUTP: REF:UNIT? <cr> - the calibrator returns VAR
OUTP:MHAR:UNIT(?) <CPD> { PRMS | PFUN }
This command defines how are evaluated higher harmonic components.
<CPD>

PRMS – % of RMS value

PFUN – % of Fundamental harmonic value
If query is sent, calibrator returns selected unit.
OUTP:MHAR:UNIT PRMS <cr> - harmonics are expressed as "% of RMS"
Example:
OUTP: MHAR:UNIT? <cr> - the calibrator returns PRMS
