3.4 Starting a Test
────────────────────────────────────────────────────
Range Selection Switch Output voltage knob
Set an output voltage using
the output-voltage knob.
NOTE
Current measurement range Maximum test time Pause
I ≦60 mA Continuous None
60 mA ＜ I ≦100 mA 30 minutes 30 minutes
100 mA ＜ I ≦ 120 mA 10 minutes 30 minutes
NOTE
The Double Action increases the safety of testing by preventing operational errors.
Refer to Section 4.5 Double Action
If you turn the output-voltage knob fully clockwise, the voltage may exceed the set
output-voltage range.
■
Rated time for output voltages (at an ambient temperature of 40℃)
The transformer capacity of the unit is approximately half the rated output. Use the
unit within the rated time. If the rated time is exceeded, the unit may overheat and
thereby cause the thermal fuse for the internal circuit to blow out.
･
If the test time is set to OFF, the comparative-voltage value becomes ineffective,
thereby facilitating output-voltage adjustments.
･
The output-voltage range can only be changed in the READY state. The range
cannot be changed in other states, even using the Range Selection switch.
