Judgement function
Judgement method/action
• The PASS signal is output at the timing preset on PASS HOLD. If HOLD is set, the PASS signal is output continuously until
the STOP signal is input.
• The UPPER FAIL signal and the LOWER FAIL signal are output continuously until the STOP signal is input.
• The FAIL and PASS buzzer volumes are adjustable. However, they cannot be adjusted individually, as they are set in common.
Setting range for the upper current (UPPER) 0.01 mA to 110 mA AC 0.01 mA to 110 mA AC / 0.01 mA to 11 mA DC
Setting range for the lower current(LOWER) 0.01 mA to 110 mA AC(With the LOWER OFF function) 0.01 mA to 110 mA AC /0.01 mA to 11 mA DC (With the LOWER OFF function)
Judgement accuracy (*3) ±(3% of setting + 20 μA) [After the offset cancel function is activated, if the scanner is mounted]
Current detection method The absolute current values are integrated and compared with the reference value.
Response-speed switching function The current-detection response speed for UPPER FAIL judgement can be set to FAST/MID/SLOW (for AC hipot testing only).
*3 In AC hipot testing, a current fl ows into the stray capacity of measurement leadwire and fi xtures. When the optional high-voltage scanner TOS9220/9221 is used, a current of
approximately 22
μA/kV fl ows into the stray capacity of each scanner. The table below shows the approximate currents fl owing into such stray capacity.
When the LOW terminal is set to GND, a current fl owing into the stray capacity is added for measurement purposes to the current fl owing into the DUT. In particular, for high-sensitivity, high-
accuracy judgement, it is necessary to add the current fl owing into the stray capacity to the lower/upper current.When the LOW terminal is set to FLOAT, the effect of the current fl owing into
the stray capacity is negligible. If the offset cancel function is used, the current fl owing into the stray capacity can be eliminated from the measurement.

*4 With the GND set to GUARD, current measurement is disabled if the part of the DUT connected to the LOW terminal is grounded, which poses extreme danger. Never ground the DUT.
In ordinary operation, set the GND to LOW.

Hold function The measured current at the end of the test is held during the PASS period.
Selection of LOW/GUARD for the GND (*5) Selection permitted for current measurement between the mode for the GND point connected to the LOW terminal, and the mode using guard.
LOW Connects the GND point to the LOW terminal. Measures the current fl owing to the LOW terminal (chassis) (for normal operation).
GUARD Sets the GND point as guard. Measures the current fl owing to the LOW terminal, but does not measure the current
fl owing to the chassis (for high-sensitivity, high-accuracy measurements).

Hipot Tester with Insulation Resistance Test
Judgement Judgement method Display Buzzer SIGNAL I/O
UPPER FAIL When the tester detects a current exceeding the upper current,
it cuts off the output and makes an UPPER FAIL judgement.
In DC hipot testing, however, no judgement is made
until the judgement wait time (WIT TIME) has elapsed.

LOWER FAIL When the tester detects a current below the lower current,
it cuts off the output and makes a LOWER FAIL judgement.
However, no judgement is made during the voltage rise time (RISE TIME)
or voltage fall time (FALL TIME) in AC hipot testing.

PASS When the preset time has elapsed without any abnormalities,
the tester cuts off the output and makes a PASS judgement.
