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:
Table C-1. Equipment Required for Verification Tests
Equipment Characteristics Recommended Model
Digital Voltmeter
Resolution: 10 nV @ 1 V
Readout: 8 1/2 digits
Accuracy: 20 ppm
Agilent 3458A
Current Monitor Resistor
l00 A, 0.001
Ω
, 0.04%, 100 W
Guildline 9230/100
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.
