TOS5302
Current detection response speed Can be switched between three levels: Fast, Mid, Slow
Judgment

Judgment method and judgment
operation
• If PASS HOLD is enabled, the PASS signal is generated continuously until the TOS5300
Series receives a STOP signal.
• The UPPER FAIL and LOWER FAIL signals are generated continuously until the TOS5300
Series receives a STOP signal.
• The FAIL and PASS buzzer volume levels can be changed.
• For PASS judgments, the length of time that the buzzer sounds for is fixed to 0.2
seconds. Even if PASS HOLD is enabled, the buzzer turns off after 0.2 seconds.
Upper limit setting range 0.03 MΩ to 5.00 GΩ
Lower limit setting range 0.03 MΩ to 5.00 GΩ
Judgment accuracy
(the same for UPPER and LOWER)
Measurement accuracy + 2 digits
Humidity: 20 %rh to 70 %rh (no condensation). No interference caused by wobbly
test leads or other problems.
For judgments of 5 μA or less, a test time of at least 1.0 seconds is necessary.
If the current detection response speed is set to Mid, a test time of at least 0.3
seconds is necessary. If the current detection response speed is set to Slow, a test
time of at least 0.5 seconds is necessary.
Time Voltage rise time 10 ms (TYP)
Test time 0.1 s to 999 s, can be turned off (TIMER OFF)
Resolution 0.1 s to 99.9 s: 0.1 s. 100 s to 999 s:1 s.
Accuracy ± (100 ppm + 20 ms)
1 Humidity: 20 %rh to 70 %rh (no condensation). No bends in the test leads.

SIGNAL I/
O
UPPER
FAIL
If a resistance that is greater than or
equal to the upper limit is detected, the
output is turned off, and an UPPER FAIL
judgment occurs. This judgment is not
performed during voltage rise time
(Rise Time).
FAIL LED
lights; OVER

on the screen
ON
Generates
a U-FAIL
signal
LOWER
FAIL
If a resistance that is less than or equal
to the lower limit is detected or if a
problem occurs during the voltage rise
time (Rise Time), the output is turned
off, and a LOWER FAIL judgment occurs.
FAIL LED

signal
PASS
If the specified time elapses without
any problems, the output is turned off,
and a PASS judgment occurs.
