CALibrate:LCURR COMMAND
CAL:LCURR
Syntax:
Short Form: CAL:LCURR {MIN | MAX | ZERO}
Long Form: CALibrate:LCURR {MIN | MAX | ZERO}
Description:
Selects low current range (1/4 scale) Current calibration, only effective with power supply in
Calibrate status.
CAL:LCURR ZERO selects Low Current Range Zero Calibration. CAL:LCURR MIN
selects Low Current Range Full Scale Negative Calibration. CAL:LCURR MAX selects Low Current
Range Full Scale Positive Calibration. Normally Low Current Range Zero is done first, then Low Cur-
rent Range Full Scale Positive Calibration.
Related Commands:
CAL:STAT, CAL:VOLT, CAL:CURR,
CAL:ZERO, CAL:DATA, CAL:DPOT, CAL:SAVE. (See example, Figure B-1.)
B.10 CALibrate:LVOLT COMMAND
CAL:LVOLT
Syntax:
Short Form: CAL:LVOLT {MIN | MAX | ZERO}
Long Form: CALibrate:LVOLT {MIN | MAX | ZERO}
Description:
Selects low voltage range (1/4 scale) Voltage calibration, only effective with power supply in
Calibrate status.
CAL:LVOLT ZERO selects Low Voltage Range Zero Calibration. CAL:LVOLT MIN
selects Low Voltage Range Full Scale Negative Calibration. CAL:LVOLT MAX selects Low Voltage
Range Full Scale Positive Calibration. Normally Low Voltage Range Zero is done first, then Low Volt-
age Range Full Scale Positive Calibration.
Related Commands:
CAL:STAT, CAL:VOLT, CAL:CURR,
CAL:ZERO, CAL:DATA, CAL:DPOT, CAL:SAVE. (See example, Figure B-1.)
B.11 CALibrate:SAVE COMMAND
CAL:SAVE
Syntax:
Short Form: CAL:SAVE
Long Form: CALibrate:SAVE
Short Form: CAL:SAVE DATE <string>
Long Form: CALibrate:SAVE DATE <string>
where DATE is optional allowing <string> of up to 12 contiguous characters identifying calibration date
to be saved. Active DATE <string > is returned by *IDN? query.
Description:
Saves computed calibration values in non-volatile memory.
This command saves only the calibra-
tion values computed after entering Calibration status. If, for example, only Voltage calibration was
performed, these are the only values saved. These values are stored in Flash Memory (see PAR.
4.7.4). Previous values are not lost, and can be restored (see PAR. 4.7.4.1). This command should be
the last command before exiting Calibrate status. CAL:STAT, CAL:DATA, CAL:DPOT, CAL:VOLT,
CAL:CURR, CAL:ZERO. (See example, Figure B-1.)
B.12 CALibrate:VOLTage COMMAND
CAL:VOLT
Syntax:
Short Form: CAL:VOLT {MIN | MAX | ZERO}
Long Form: CALibrate:VOLT {MIN | MAX | ZERO}
Description:
Selects Voltage calibration, only effective with power supply in Calibrate status.
CAL:VOLT ZERO selects Voltage Zero Calibration. CAL:VOLT MIN selects Voltage Full Scale Nega-
tive Calibration. CAL:VOLT MAX selects Voltage Full Scale Positive Calibration. Normally Voltage
Zero is done first, then Voltage Full Scale Positive Calibration.
Related Commands:
CAL:STAT,
CAL:VOLT, CAL:CURR, CAL:ZERO, CAL:DATA, CAL:DPOT, CAL:SAVE. (See example, Figure B-1.)
B.13 CALibrate:VPRotect COMMAND
CAL:VPR
Syntax:
Short Form: CAL:VPR {MIN | MAX}
Long Form: CALibrate:VPRotect {MIN | MAX}
Description:
Selects Voltage Protection limit calibration, only effective with power supply in Calibrate sta-
tus.
CAL:VPR MAX selects maximum positive voltage protection limit calibration. CAL:VPR MIN
selects maximum negative voltage protection limit calibration.
Related Commands:
CAL:STAT,
CAL:ZERO, CAL:DATA, CAL:SAVE.
B.14 CALibrate:ZERO COMMAND
CAL:ZERO
Syntax:
Short Form: CAL:ZERO
Long Form: CALibrate:ZERO
Description:
Sets output to zero while calibration equipment connections are changed.
This command is used
when changing from Voltage to Current calibration or vice-versa. CAL:ZERO sets output voltage and
current to zero. The user then connects or disconnects the shunt resistor or the digital voltmeter from
the output terminals of the power supply as required for the subsequent Voltage or Current calibration.
The next command should select the new parameter to be calibrated.
