To Prepare the Multimeter for Use

Chapter 1 Quick Start

The following steps help you verify that the multimeter is ready for use.

1 Check the list of supplied items.

Verify that you have received the following items with your multimeter. If anything is missing, contact your nearest Agilent Sales Office.

One test lead kit.

One power cord.

This User’s Guide.

One Service Guide.

One folded Quick Reference card.

Certificate of Calibration.

2Connect the power cord and turn on the multimeter.

The front-panel display will light up while the multimeter performs its power-on self-test. The GPIB bus address is displayed. Notice that the multimeter powers up in the dc voltage function with autoranging enabled.

To review the power-on display with all annunciators turned on, hold down Shift as you turn on the multimeter.

3Perform a complete self-test.

The complete self-test performs a more extensive series of tests than those performed at power-on. Hold down Shift as you press the Power switch to turn on the multimeter; hold down the key for more than 5 seconds. The self-test will begin when you release the key.

If the self-test is successful, “PASS” is displayed. If the self-test is

not successful, “FAIL” is displayed and the ERROR annunciator turns on. See the Service Guide for instructions on returning the multimeter to Agilent for service.
