Verification and Performance Tests

Introduction

This document contains test procedures to verify that the dc power supply is operating normally and is within published specifications. There are three types of tests as follows:

Built-in Self Tests

These tests, run automatically when the power supply is turned on, check most

 

of the digital circuits and the programming and readback DACs.

Operation Verification

These tests verify that the power supply is probably operating normally but do

 

not check all of the specified operating parameters.

Performance Tests

These tests check that the supply meets all of the operating specifications as

 

listed in the User’s Guide.

NOTE: The dc power supply must pass the built-in self-tests before calibration or any of the verification or performance tests can be performed. If the supply fails any of the tests or if abnormal test results are obtained, refer to the troubleshooting procedures in Chapter 3. The troubleshooting procedures will determine if repair and/or calibration is required.

Test Equipment Required

Table 2-1 lists the equipment required to perform the verification and performance tests. A test record sheet with specification limits and measurement uncertainties (when test using the recommended test equipment) may be found at the back of this section.

WARNING:

SHOCK HAZARD. These tests should only be performed by qualified personnel. During the

 

performance of these tests, hazardous voltages may be present at the output of the supply.
