M133C Electric Power/Energy Calibrator
Operation manual
116
<CPD>
represents the control mode of energy counting.
PACK – Packet mode energy counting is controlled by time to deliver specific “Packet” of
energy
CNT1 – energy counting mode is controlled by pulses on input 1
CNT2 – energy counting mode is controlled by pulses on input 2
TIM1 – energy timer mode is controlled by pulses on input 1
TIM2 – energy timer mode is controlled by pulses on input 2
FR1 – frequency measuring on input 1
FR2 – frequency measuring on input 2
FR3 – frequency measuring on multimeter input V/COM
If query is sent, calibrator returns the selected control mode.
Example:
EDC:CONT PACK selects the Packet control mode which is controlled by time
Note:
Command switches the calibrator in Energy DC mode.
[SOUR]:EDC:TIME(?) <DNPD>
This command sets the time in Energy DC “Packet” control mode.
<DNPD>
Parameter represents the value of time expressed in s.
If query is sent, calibrator returns the value of time using standard exponential format. Example:
120s is returned as 1.002.
Example:
Time 60s:
EDC:TIME 60
Notes:
Command switches the calibrator in Energy DC mode.
[SOUR]:EDC:CONS(?) <DNPD>
This command sets number of pulses per one kWh (pulses generated by energy meter).
<DNPD>
Parameter represents the value number of pulses per one kWh.
If query is sent, calibrator returns set value using standard exponential format. Example: 400.0
i/kWh is returned as 4.002.
Example:
Number of pulses 1000 i/kWh:
EDC:CONS 1000.0
