Withstanding Voltage and Insulation Resistance Tests | Finishing the Test and Viewing the Judgment
Judgment types and operation
When a test finishes, the judgment result is shown in the test status.
Clearing the judgment result
Press STOP to clear the judgment result. The product is ready to start another test.
Upper-FAIL Lower-FAIL Upper-FAIL (dV/dt)
Condition A current greater than or equal
to the upper limit was
measured.
A current less than or equal to
the lower limit was measured.
When Delay Auto is set to on
in a DCW test and the output
voltage is 200 V or more, the
voltage rise rate (dV/dt) is less
than approximately 1
V/s
before starting a judgment.
Display The test status shows “Upper-
FAIL” until the judgment result
is cleared.
The test status shows “Lower-
FAIL” until the judgment result
is cleared.
The test status shows “Upper-
FAIL (dV/dt)” until the
judgment result is cleared.
Buzzer The buzzer continues to sound
until the judgment result is
cleared.
The buzzer continues to sound
until the judgment result is
cleared.
The buzzer continues to sound
until the judgment result is
cleared.
SIGNAL I/O
connector
U FAIL signal is output until the
judgment result is cleared.
L FAIL signal is output until the
judgment result is cleared.
U FAIL signal is output until the
judgment result is cleared.
Lower-FAIL (dV/dt) Contact-FAIL PASS
Condition When Delay Auto is set to on
in a IR test and the output
voltage is 200 V or more, the
voltage rise rate (dV/dt) is less
than approximately 1 V/s
before starting a judgment.
Continuity between the test
lead and EUT could not be
confirmed when the scanner is
used with Contact Check
enabled.
Upper-FAIL ,Lower-FAIL, or
Contact-FAIL judgment did not
occur during the test.
Display The test status shows “Lower-
FAIL (dV/dt)” until the
judgment result is cleared.
The test status shows
“Contact-FAIL” until the
judgment result is cleared.
The test status shows “PASS”
until the time specified by Pass
Hold elapses. Then the
judgment result is cleared.
Buzzer The buzzer continues to sound
until the judgment result is
cleared.
The buzzer continues to sound
until the judgment result is
cleared.
The buzzer sounds for 50 ms
(regardless of the Pass Hold
time).
SIGNAL I/O
connector
L FAIL signal is output until the
judgment result is cleared.
Both U FAIL and L FAIL signals
are output simultaneously until
the judgment result is cleared.
PASS signal is output until the
judgment result is cleared.
