Timer function
Item Specifications
Behavior based on judgment Judgment based on resistance or sensing voltage can be selected. The
output is shut off when a judgment is made. Buzzer volume level can be set in
the range of 0 (OFF) to 10 for pass and fail separately. In an auto test, the
buzzer is valid only for the judgment that takes place at the end of the
program.
UPPER
FAIL
Judgment
method
UPPER FAIL results when a resistance greater than or equal to the Upper
limit is detected or when a sensing voltage is detected. Judgment is not made
during a contact check.
Display “Upper-FAIL” is displayed.
Buzzer On
SIGNAL I/O The Upper-FAIL signal is generated continuously until a STOP signal is
received.
LOWER
FAIL
Judgment
method
LOWER FAIL results when a resistance less than or equal to the lower limit
(Lower) is detected or when a sensing voltage is detected.
Display “Lower-FAIL” is displayed.
Buzzer On
SIGNAL I/O The Lower-FAIL signal is generated continuously until a STOP signal is
received.
PASS Judgment
method
PASS judgment is made if Upper-FAIL or Lower-FAIL has not occurred when
the test time elapses.
Display “PASS” is displayed.
Buzzer On (fixed to 50 ms)
SIGNAL I/O The PASS signal is generated for the length of time specified by the Pass
Hold setting. If Pass Hold is set to Infinity, the PASS signal is generated
continuously until a STOP signal is received.
Resistance
judgment
Upper limit setting range 0.000 1 Ω to 10.000 0 Ω
Lower limit setting range 0.000 0 Ω to 9.999 9 Ω
Judgment accuracy ±(2 % of setting + 3 mΩ)
Voltage
judgment
Upper limit setting range 0.001 V to 5.000 V AC/DC
Lower limit setting range 0.000 V to 4.999 V AC/DC
Judgment accuracy ±(2 % of setting + 0.05 V)
Calibration Calibrated using a pure resistive load (with the rms of a sine wave for AC)
Contact check function Checks that current flows through the test leads and then starts the test. (OFF
setting available)
Item Specifications
Current rise time settings range 0.1 s to 200.0 s
Current fall time setting time
1
0.1 s to 200.0 s, OFF
Test time 0.1 s to 1 000.0 s, OFF
Accuracy ±(100 ppm of setting + 20 ms) (excluding the fall time)
1 This setting is used only when a PASS judgment occurs. During a DC test, the voltage may not drop all the way within
the set time because of the electrostatic capacity inside the product and the EUT.
