3.4 Starting a Test
______________________________________________________________________________________________
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
If the test time is set to OFF, the comparative-voltage value becomes ineffective,
thereby facilitating output-voltage adjustments.
3.4.2 Executing a Test
DANGER
Observe the following precautions to avoid electric shock.
Make sure that no high voltage is being applied to the output, confirm
the following items, and output voltage.
(1) The analog voltmeter reads 0 kV.
(2) The DANGER lamp is OFF.
(3) The
READY
lamp is lit (it is off in the Double Action mode).
A voltage is output during output-voltage setting using the
outputvoltage
adjustment knob. Never touch the HIGH terminal, H.V. TEST LEAD, or
tested object.
CAUTION
For output, the unit uses a high-voltage transformer that boosts the power
voltage. If an unstable power voltage is used to operate the unit, the tested
object may be damaged by the distortion of the output-voltage waveform
and by the output of a voltage higher than the preset voltage.
If a capacity load is applied to the tested object, the output voltage may
exceed the preset voltage, thereby damaging the equipment.
Continuous output of a high voltage may heat the bottom of the unit. Take
special care when handling the unit (e.g. transporting the unit).
NOTE
Priority for control of the
START
key is in the following order: the
START
key on
the REMOTE CONTROL BOX, the external I/O, and the front panel of the unit.
Connecting the switch signal line plug on the REMOTE CONTROL BOX disables
the
START
key on the front panel of the unit and the start signal for the external
I/O.
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.
