Calibration

Introduction

The power module may be calibrated either over the GPIB from a controller or from an Agilent 66001A Modular Power System keyboard. Instructions are included for either method. The procedures given here apply to all Series 66l0xA Power Modules.

Note	The Agilent 66000A mainframe does not require calibration.

Enabling Or Disabling The Calibration Function

There are two ways of controlling access to the calibration function. One is by hardware and the other is with software.

Hardware Control

The CAL positions of the power module function switch (see Table 2-1 in "Chapter 2 Installation") allows hardware control over the calibration function. The factory-default setting is for normal calibration. Setting the switches to the Inhibit calibration position prevents any calibration from being performed.

Software Control

The password parameter of the CAL: STAT command allows software control over the calibration function. The standard factory password is the module model number (for example, 66102 for the Agilent 66102A). By changing the password, you can either restrict or allow unlimited access to the calibration function (see "Changing the Calibration Password").

Changing The Calibration Password

You can change the password only when the module is in the calibration mode (which requires you to know the present password). To change the password from 66101 to 81591, send the following commands:

CAL:STAT ON, 66102

CAL:PASS 81591

If you change the password to 0, then all password protection is removed. The Calibration Subsystem then will accept the CAL: STAT ON command without a password.

Performing a Calibration

Perform the procedures in the order given. The assumed password is 66102; use your actual password in the procedures.

Important These instructions do not include verification procedures. If you need to perform verification as part of your calibration procedure, refer to the Series Agilent 66I0xA Service Manual.
