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
Operation Verification
Performance Tests
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 (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.
Table 2-1. Test Equipment Required for Verification and Performance Tests
Type
Current Monitor Resistor
DC Power Supply
Digital Voltmeter
Electronic Load
GPIB Controller
These tests, run automatically when the power supply is turned on, check most
of the digital circuits and the programming and readback DACs.
These tests verify that the power supply is probably operating normally but do
not check all of the specified operating parameters.
These tests check that the supply meets all of the operating specifications as
listed in the Operating Manual.
