Performing The Configuration Procedure - Agilent Technologies 66319B User Manual

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
Press Shift Cal and scroll to the CAL PASS command.
3.
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).
If you have forgotten the password, you can set the calibration switch on the A2 Interface board to bypass
the password. Refer to the Service Manual for Agilent Model 66111A, 66311A/B/D, 66309B/D (p/n
5964-8176) for information on the location and function of the calibration switch. When you have
bypassed the password with the switch, you can enter a new password using the CAL:PASS command.
The new password becomes active after CAL:SAVE and CAL:OFF are programmed. Then, with the
calibration switches in the normal position, you can turn calibration on using the new password.
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.
