POWER
INTERRUPT
This test r
equires a numeric entry value equal to the test number. The tests are grouped as follows:
• Test numbers 1 through 15 are for all Standard and Groups. See Figure 9-6 for details of the tests.
• Test numbers 16 a
nd 17 for all equipment that does not incorporate digital circuit. Test number 16 will
drop the output to zero voltage for 50 ms. Test number 17 will drop the output to zero voltage for 200
ms
. Test number 18 is used for DC equipment and will drop the output for 1 sec.
• Test numbers 21 through 26 are applicable for Groups 2 and 3 only. Output frequency will be set to the
F1 value for 1 second prior to the test. The output frequency will remain set to the F2 value when the
test is completed. This will allow the user to apply sequence of power interrupts. See Figure 9-7 for
detail of the tests.
