Test Equipment Required; Performance Test - HP 6236A Operating And Service Manual

5-1 INTRODUCTION
SECTION V
MAINTENANCE
5-5 Table 5-1 lists the test equipment required to per-
form the various procedures described in this section.
5-2 Upon receipt of the power supply, the performance
test of Paragraph 5-6 can be made. This test is suitable for
incoming inspection. Section III contains a quick but less
comprehensive checkout procedure which can be used in
lieu of the performance test if desired.
5-3 If a fault is detected in the power supply while
making the performance test or during normal operation:
proceed to the troubleshooting procedure in Paragraph 5-32.
After troubleshooting and repair, repeat the performance
test to ensure that the fault has been properly corrected and
that no other faults exist. Before performing any mainte-
nance checks, turn on the power supply and allow a half-
hour warm-up.
5-4 TEST EQUIPMENT REQUIRED
5-6 PERFORMANCE TEST
5-7 The following test can be used as an incoming in-
spection check and appropriate portions of the test can be
repeated to check the operation of the instrument after
repairs. If the correct result is not obtained for a particular
check, proceed to the troubleshooting procedures of
Para~
graph 5-32.
- - CAUTION--
Before applying power to the supply, make
certain that its line voltage selector switch (S3)
is set for the line voltage to be used. (See
CA UTION notice in Paragraph 3-2 for addi-
tional information on S3.)
