OUTP:ENER:UNIT(?) <CPD> { WS | WH }
This command sets unit used for energy.
WS - energy is displayed in Ws, VAs, VArs
WH - energy is displayed in Wh, VAh, VArh
Energy unit remains valid even after the calibrator is switched off and back on.
If query is sent, calibrator returns set energy unit { WS | WH }.
Example:
OUTP:ENER:UNIT WH <cr> - sets energy unit Wh
OUTP: ENER:UNIT? <cr> - the calibrator returns WH
OUTP:ENER:MVOL(?) <CPD> { OFF | ON | 0 | 1 }
This command activates or deactivates Maintain Voltage Signal function.
OFF or 0 – function is not active
ON or 1 – fucntion is active
State of the function remains valid even after the calibrator is switched off and back on.
If query is sent, calibrator returns state of the fucntion { 0 | 1 }.
Example:
OUTP:ENER:MVOL ON <cr> - activates Maintain Voltage Signal function
OUTP: ENER:MVOL? <cr> - the calibrator returns 1
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 4.002.
Example:
Number of pulses 1000 i/kVArh:
OUT:REF:CONS 1000.0
OUT:REF:UNIT VAR
