Even in the FAIL state, when UPPER FAIL is activated, the
U-FAIL
――――――――――
signal
becomes LOW level. Similarly, with LOWER-FAIL, the
L-FAIL
――――――――――
signal
becomes LOW level. When the FAIL Hold function is set, the signal remains
at LOW level until the Hold function is disabled.
If a withstand voltage test fails, the
W-FAIL
――――――――――
signal becomes LOW level.
Similarly, if an insulation resistance test fails, the
I-FAIL
――――――――――
signal becomes
LOW level. In the case of UPPER-LOWER FAIL, which is activated when
the measured voltage value fails to reach the comparative-voltage value in
voltage mode, the
U-FAIL
――――――――――
and
L-FAIL
――――――――――
signals are at LOW level
simultaneously.
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.
