Mean-value responsive (response time of 200 ms)
The measured current at the end of the test is held during the PASS period.
Performs calibration using the root-mean-square value of a sine wave with a
pure resistive load
Selection permitted for current measurement between the mode for the GND
point connected to the LOW terminal, and the mode using guard.
Connects the GND point to the LOW terminal. Measures the current flowing to
the LOW terminal (chassis) (for normal operation).
Sets the GND point as guard. Measures the current flowing to the LOW terminal,
but does not measure the current flowing to the chassis (for high-sensitivity,
high-accuracy measurements).
Judgement Judgement method
When the tester detects a current
exceeding the upper reference, it
cuts off the output and makes an
UPPER
UPPER FAIL judgement. How-
FAIL
ever, no judgement is made until
the judgement wait time (WAIT
TIME) has elapsed.
When the tester detects a current
below the lower reference, it cuts
off the output and makes a
LOWER
LOWER FAIL judgement. How-
FAIL
ever, no judgement is made dur-
ing the voltage rise time (RISE
TIME).
When the preset time has
elapsed without any abnormali-
PASS
ties, the tester cuts off the output
and makes a PASS judgement.
• 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.

The absolute current values are integrated and compared with the reference
value.
The current detection response for UPPER FAIL judgement can be set to FAST/
