Verification Tests
Introduction The two levels of test procedures described in this chapter are used to verify
that the relay multiplexer module:
• is fully functional (Functional Verification);
• meets all testable specifications (Performance Verification).
Test Conditions/
Procedures
See Table 1-1 for test equipment requirements. You should complete the
Performance Verification tests at least once a year. For heavy use or severe
operating environments, perform the tests more often. It is assumed that the
temperature is no greater than 25
o
C and the relative humidity is no greater
than 40%.
The verification tests assume that the person performing the tests
understands how to operate the mainframe, the relay multiplexer, and
specified test equipment. The test procedures do not specify equipment
settings for test equipment, except in general terms. It is assumed that a
qualified, service-trained technician will select and connect the cables,
adapters, and probes required for the test.
Performance
Test Record
The results of each Performance Verification test may be recorded in the
Performance Test Record (Table 2-1). You can make a copy of this form,
if desired.
Verification Test
Examples
Each verification test procedure includes an example program that performs
the test. All example programs assume the following:
• controller is an HP 9000 Series 200/300 computer;
• programming language is BASIC;
• switch address is 70914;
• switch card number is 1;
• DMM is an Agilent 3458A.
Test Fixture A test fixture is required for the Performance Verification tests. A test
fixture can be manufactured from the Agilent E1460A terminal block. It is
recommended that you order an extra terminal block to use as a test fixture,
so that you do not have to re-wire the terminal block each time these tests
are performed. The terminal block part number is E1460-80001. Figure
2-1 shows how the test fixture should be wired.
