TOS8030 Specifications 47
*3 A FAIL signal is continuously output until STOP is input.
*4 The volume of a buzzer can be adjusted. However, it cannot be individually adjusted with respect
to FAIL and PASS judgments.
*5 In an AC withstanding voltage test, a current also flows in stray capacities such as measurement
leads and devices. The approximate current values flowing in these stray capacities are as shown
in the table below.
*6 Voltage required to make FAIL judgment with the output terminals short-circuited due to internal
resistance in the output circuit.
Judgment function
Judgment method
Compares the reference values and measured leakage current. The result
is returned as a PASS or FAIL.
Judgment action
FAIL judgment
• If a current exceeding the reference value is detected:
• The FAIL lamp is lit,
• A FAIL signal is output from the SIGNAL OUT terminal (*3), and
• The buzzer sounds. (*4)
PASS judgment
• When there are no abnormalities even after the set time has elapsed:
• The PASS lamp is lit.
• A PASS signal is output from the SIGNAL OUT terminal, and
• The buzzer sounds. (*4)
Reference value
x0.1 mA range: Can be set from 0.1 mA to 9.9 mA in 0.1 mA steps.
x1 mA range: Can be set from 1 mA to 11 mA in 1 mA steps.
Judgment accuracy (*5)
Iref ≥ 1 mA: ± (5% + 20 µA)
Iref < 1 mA: ± (5% + 40 µA)
Iref: Reference value
Current detection method Integrates the absolute current value to compare it to the reference value.
Calibration
Use a pure resistive load to make calibrations based on sine-wave rms
values.
Output voltage at no-load that
is required for detection (*6)
Approx. 600 V when set to 10 mA
