Verification
Introduction
This appendix provides operation verification test procedures. The tests do not check all the operating parameters, but
verify that the power supply is performing properly. The required test equipment and acceptable test results are specified in
tables at the end of this appendix.
Note
Performance Tests, which check all the specifications of the power supply, are given in the Service Manual.
Test Equipment Required
List of Equipment
The following equipment is required to perform the tests:
Equipment
Digital Voltmeter
Current Monitor Resistor
Current Monitoring Resistor
The 4-terminal current-monitoring resistor listed in Table B-1 is required to eliminate output current measurement error
caused by voltage drops in leads and connections. The specified resistors have special current-monitoring terminals inside
the load connection terminals. Connect the digital voltmeter directly to these current-monitoring terminals.
