3.4.1 Setting the Output Voltage
DANGER
To avoid any life-threatening electric shock accidents, ensure that the
following rules are observed.
･
The AC Withstanding HiTester is a dangerous product which
discharges high voltages. To prevent getting electrocuted, always
wear high-voltage protective rubber gloves when carrying out any
operation.
･
Be careful when using the product and ensure that you do not touch
this product, any tested object that is connected or any H.V. Test
Lead, etc.
･
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.
Before starting a test, make output voltage settings using the output-voltage knob. If
a comparative-voltage value has already been set, press the
START
key and set an
output voltage within 5 seconds after pressing the
START
key. If the setting is not
successful, the test switches to the FAIL state.
(1) In accordance with the instructions given in 2.9, "Connection to the Measured
Equipment," connect the probe to the tested object.
(2) Make sure the analog voltmeter is at 0 kV, the DANGER lamp is OFF, and the
unit is in the READY state.
(3) Set the output-voltage range using the Range Selection switch.
(4) Press the
START
key. TEST will light up and a voltage will be output.
(5) Set an output voltage using the output-voltage knob. The output-voltage knob
increases the output voltage when turned clockwise, and decreases the voltage
when turned counterclockwise. The maximum value is 2.5 kV or 5.0 kV,
depending on the output-voltage range set in Step (3). The output voltage is
displayed on the analog voltmeter and the fluorescent indicator.
(6) Upon completion of the output-voltage settings, press the
STOP
key to stop the
output.
