• When the measured current is less than the lower cutoff current:
Assuming that the lower cutoff current is set at 1 mA and the lower pass/fail

will be as follows.
LOWER FAIL
.
When the Tester has made a FAIL judgement, the
LOWER FAIL
message
31
will appear and the following actions will take place.
• The tester terminates the test and cuts off the test voltage.
• The
TEST
message
29
disappears.
• The TEST signal of the
SIGNAL I/O
connector
37
is turned OFF.
• The
DANGER
lamp
9
goes out. (It does not go out so far as there remains a
residual test voltage in the output circuit.)
• The H.V ON signal of the
SIGNAL I/O
connector
37
is turned OFF. (It is not
turned off so far as there remains a residual test voltage in the output circuit.)
• The
UPPER FAIL
or
LOWER FAIL
message 31 disappears.
• The U FAIL or L FAIL signal of the
SIGNAL I/O
connector
37
is turned OFF.
• The buzzer stops.
The FAIL judgement does not reset automatically. To reset it, press the
STOP
