MEASure/FETCh Command

KIKUSUI Electronics Corp.

PWR-01 Interface Manual

FETC:CURR/ MEAS:CURR

Queries the measured value of the current.
When you are using the multichannel function, use <n> to specify the channel num-
ber.

Command

FETCh[<n>][:SCALar]:CURRent[:DC]?

MEASure[<n>][:SCALar]:CURRent[:DC]?

(Example)

MEAS:CURR?

MEAS2:CURR?

Response

Returns the measured value of the current in NR3 format in response to
FETC:CURR?/ MEAS:CURR?. The measured voltage and the measured current
are updated alternately at 25 ms intervals.
When you are using the multichannel function, this query returns the measured
current of the specified channel in NR3 format in response to FETC<n>:CURR?/
MEAS<n>:CURR?. If you omit <n>, the measured value of the channel that was
specified by the INST command is returned.
Unit: A

FETC:VOLT/ MEAS:VOLT

Queries the measured value of the voltage.
When you are using the multichannel function, use <n> to specify the channel num-
ber.

Command

FETCh[<n>][:SCALar]:CURRent[:DC]?

MEASure[<n>][:SCALar]:CURRent[:DC]?

(Example)

MEAS:VOLT?

MEAS2:VOLT?

Response

Returns the measured value of the voltage in NR3 format in response to FETC:-
VOLT?/ MEAS:VOLT?. The measured voltage and the measured current are updat-
ed alternately at 25 ms intervals.
When you are using the multichannel function, this query returns the measured
voltage of the specified channel in NR3 format in response to FETC<n>:VOLT?/
MEAS<n>:VOLT?. If you omit <n>, the measured value of the channel that was
specified by the INST command is returned.
Unit: V
