(2) Timing chart during a test decision
The figure shows the timing chart of the unit in PASS state after a test. In
PASS state, the
TEST
―――――――
signal indicates HIGH level.
The
H.V.ON
――――――――――
signal remains at LOW level provided that the voltage between
the output terminals remains unchanged, as the signal is synchronized with
the
DANGER
lamp. (Below 30 VAC when performing an AC-withstand-
voltage test, or below 60 VDC when performing a DC-withstand-voltage test
or an insulation-resistance test)
Once the voltage reaches 0, the signal changes to HIGH level.
The
PASS
―――――――
signal changes according to the
PASS
indicator on the fluorescent
display. If the PASS hold function is enabled, the
PASS
―――――――
signal continues to
indicate LOW level until the function is disabled.
When the Hold function is disabled or the unit automatically returns to the
READY state, the
PASS
―――――――
signal becomes HIGH level and the
READY
――――――――――
signal
becomes LOW level.
In the program mode, as soon as the
PASS
―――――――
signal enters LOW level, the
FILE-END
――――――――――――――
signal enters LOW level (100 ms) as well.
