Table B-3. GPIB Calibration Error Messages

Meaning

CAL switch prevents calibration (This is a hardware disable, see the Service Manual.) CAL password is incorrect

CAL not enabled

Computed readback cal constants are incorrect

Computed programming cal constants are incorrect

Incorrect sequence of calibration commands

Changing the Calibration Password

The factory default password is 0. You can change the password when the dc source is in calibration mode (which requires you to enter the existing password). Proceed as follows:

	Action	Display
1.	Begin by pressing Shift Cal and scrolling to the CAL ON command.	CAL ON 0.0

2.Enter the existing password from Entry keypad and press Enter

Press Shift Cal and scroll to the CAL PASS command.

CAL:PASS 0

4.Enter the new password from the keypad. You can use any number with up to six digits and an optional decimal point. If you want the calibration function to operate without requiring any password, change the password to 0 (zero).

NOTE: If you want the calibration function to operate without requiring any password, change the password to 0 (zero).

Calibration Over the GPIB

You can calibrate the dc source by using SCPI commands within your controller programming statements. Be sure you are familiar with calibration from the front panel before you calibrate from a controller. Each front panel calibration command has a corresponding SCPI command. When you write your calibration program, perform the calibration procedure in the same order as the front panel procedure documented in this appendix.

The SCPI calibration commands are explained in chapter 8. Calibration error messages that can occur during GPIB calibration are shown in table B-3.
