Calibration Error Messages

Errors that can occur during calibration are shown in the following table.
Error
401 CAL switch prevents calibration (This is a hardware disable, see the Service Manual.)
402 CAL password is incorrect
403 CAL not enabled
404 Computed readback cal constants are incorrect
405 Computed programming cal constants are incorrect
406 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
1. Begin by pressing Shift Cal and scrolling to the CAL ON command.
2. Enter the existing password from Entry keypad and press Enter
3. Press Shift Cal and scroll to the CAL PASS command.
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.
