Table.1 Judgment method/action of the judgment function
• A PASS signal is output for approx. 200 ms. However, if the PASS HOLD function is set to “HOLD,” the signal is
continuously output until a STOP signal is input.
• An UPPER FAIL or LOWER FAIL signal is continuously output until a STOP signal is input.
• The buzzer volume for FAIL or PASS judgment is adjustable. However, it cannot be individually adjusted for PASS and FAIL
judgments, as they use common settings.
Table.2 Judgment accuracy of the upper/lower judgment function
• The humidity must be in the range of 20 % to 70 %rh (no condensation permitted), and there must be no
disturbance such as swinging of the test leadwires.
• The lower judgment requires a test duration of 0.5 s or more after the wait time has expired. It also requires a wait
time of 1.0 s or more for a lower judgment of 200 nA or less.

Judgment Judgment method Indication Buzzer SIGNAL I/O
UPPER
FAIL
If a resistance value equal or higher than the upper resistance
is detected, the tester shuts off the output and returns an
UPPER FAIL judgment.
FAIL lamp lights.
UPPER LED lights. ON
Outputs an
UPPER FAIL
signal.
LOWER
FAIL
If a resistance value equal or less than the lower resistance is
detected, the tester shuts off the output and returns a LOWER
FAIL judgment. Note that no judgment is made within the
judgment wait time (WAIT TIME) after the start of the test.
FAIL lamp lights.
LOWER LED lights.
ON
Outputs a
LOWER FAIL
signal.
PASS If no abnormality is found when the set test time has elapsed,
the tester shuts off the output and returns a PASS judgment.
PASS lamp lights.
ON
Outputs a PASS
signal.
