NOTE
If the current generated is several times as large as the upper-limit value, a circuit
promptly cuts off the high voltage, thereby switching the unit to

this point, an incorrect value for the measured current is displayed.

Flow of FAIL determination
1. Press the
START
key to start a test.
2.
TEST
flashes until the output voltage reaches the set test voltage.
TEST
also
flashes during the ramp-up time. When the output voltage reaches the test
voltage,
TEST
remains lit, and the reduction timer starts counting down the
test time.
3. A voltage continues to be output until the test time elapses. If the
measured current deviates from the upper- or lower-level value during this
period, the unit switches to the FAIL state.
4. Once a switch is made to the FAIL state,
FAIL
lights up, together with
UPPER
or
LOWER
. The unit stops outputting a voltage and the reduction
timer stops.
