Verification and Calibration Appendix B
Calibration
Refer to the “Equipment Required” section in this appendix for a list of the equipment required for calibration. A general outline of the procedure is as follows:
As shipped from the factory the calibration password is 0, which means password protection is removed and the ability to enter calibration mode is unrestricted. If a password has subsequently been set, you must enter the correct password - otherwise an error will occur. Once calibration has been entered, the password can be changed by the user.
You do not have to do a complete calibration. If appropriate, you may calibrate only the voltage or current functions and then save the calibration constants. You can also save the date when the calibration was preformed (see CAL:DATE <”date”>).
As each calibration sequence is completed, the instrument saves the calibration constants and begins using them.
Exit the calibration mode. Note that a Reset command (*RST) also sets the calibration state to OFF.
Calibration Procedure
| Unless instructed otherwise, connect the +sense terminal to the |
| +output, and the |
| When calibrating the unit using SCPI commands, most calibration |
| steps involve sending an *OPC? query to synchronize with the power |
| supply’s command completion before proceeding. The response from |
| the instrument must be read each time *OPC? is given. |
| The CAL:LEV and CAL:DATA commands may take several seconds to complete. |
NOTE | |
| If a timeout occurs in your VISA application, you may need to change the |
| VI_ATTR_TMO_VALUE in the ViSetAttribute function. |
Voltage Programming and Measurement Calibration
Step 1. Connect the Agilent 3458A voltage input to the output.
Step 2. Enable voltage calibration mode.

OUTP ON CAL:STAT ON
Step 3. Set the current limit high enough to allow unrestricted voltage programming.
ISET 0.5
Step 4. Select voltage calibration.
