4.3 Calibration Subsystem
The commands in this subsystem allow you to do the following:
Enter the calibration password
Calibrate the current and voltage output levels, and store new calibration constants in
nonvolatile memory.
Subsystem Syntax
CALibrate
:MEASure
:CURRent Begin current measurement calibration sequence
:SPHase Query format returns single phase current mea coefficient.
:VOLTage Begin current measurement calibration sequence
:PASSword Unlock calibration
:SAVE Save new cal constants in non-volatile memory
[:SOURce]
PHASe Phase offset calibration
:VOLTage:HRANge Query output voltage cal coefficient
CALibrate:MEASure:CURRent
Phase Selectable
This command can only be used in calibration mode. It initiates the calibration of the ac current
metering circuits and sets the reference value to calibrate to. The query format returns the actual
calibration coefficient. Use the INST:SEL or INST:NSEL to select the desired phase.
Command Syntax CALibrate:MEASure:CURRent
Parameters Reference instrument current reading
Query Syntax CALibrate:MEASure:CURRent?
Returned Parameters
Examples CAL:MEAS:CURR 12.23
Related Commands CAL:SAVE CAL:MEAS:VOLT
CALibrate:MEASure:CURRent:SPHase
This command can only be used in calibration mode and in query form. It applies only to phase 1
(Lx) or A (Ls). It returns the single-phase mode current measurement calibration coefficient for Lx
models and Ls models that have the
–MODE option. Its purpose is to be able to read the
calibration status without having to switch the AC source to single phase mode.
If the Lx or Ls is in single phase mode, this command is equivalent to the the CAL:MEAS:CURR?
query for phase 1/A except it can not be used to perform a calibration. It does not initiate a
calibration. Use the CAL:MEAS:CURR? command to do this instead.
Query Syntax CALibrate:MEASure:CURRent:SPHase?
Returned Parameters
Examples CAL:MEAS:CURR:SPH?
Related Commands CAL:SAVE CAL:MEAS:VOLT
CALibrate:MEASure:VOLTage
Phase Selectable
This command can only be used in calibration mode. It initiates the calibration of the ac voltage
metering circuits. The query format returns the actual calibration coefficient. Use the INST:SEL or
INST:NSEL to select the desired phase.
