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
3.
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.
Performing the Configuration Procedure
The configuration procedure lets you customize the power-on/*RST defaults of the following settings:
• Output compensation mode
• Output coupling
• Output relay mode
• Output OVP setting
You can only customize these default settings from the front panel by first accessing the calibration
menu. In this way, any changes to the configuration settings are secured by the calibration password
protection feature. All configuration settings can also be returned to the factory state using the
configuration procedure.
To access the front panel commands for the configuration function, the calibration state must be enabled.
If a calibration password is set, the password must be provided to enable calibration. Once calibration is
enabled, the front panel will be in Meter mode. The configuration function can only be invoked while in
meter mode. If for some reason the front panel is not in meter mode, press the Meter key. To access the
configuration menu, you must then simultaneously press the Local and the Recall keys.
