8.6 Timing Chart
118
Changing during auto tests
This figure shows the switching timing chart of the instrument when it is in the
auto-test mode. In this mode, withstand-voltage and insulation-resistance tests
are conducted successively.
The instrument switches to the next test when the output-voltage value has
dropped sufficiently. The TEST
signal remains at LOW level until a series of
tests is completed.
