PERFORMANCE CHECK
The procedure given below can be used to check equipment
performance in the shop after routine maintenance as
described in Section 11, or after making repairs as indicated in
Section 12. The procedure may be used in the field prior to
conducting tests to confirm that the equipment is operating
properly and thereby ensure valid test results.
After the equipment is set up, the performance check can be
completed in about five minutes.
CAUTION: Since high voltage will be developed
during this test, persons conducting the test must be
familiar with the safety precautions normally followed
when operating high voltage equipment and must take
all necessary measures to avoid shock hazard.
Follow the procedure given below:
1. Set up the equipment as indicated in Section 7. Suspend
the output lead so that the high voltage clip is clear of all
objects by at least 18 inches (45 cm).
2. Set the voltmeter range to 15 kV and the megohmmeter
multiplier to X1K, stabilizer "OUT".
3. Operate the set according to the procedure given in
Section 8, raising the voltage to 15 kV. The megohmmeter
should indicate more than 200 megohms. That is, the
actual resistance should be above 300,000 megohms, with
internal leakage making the difference.
