5.4.1 Executing a Test
DANGER
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).
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.
NOTE
The
UP/DELAY
lamp lights during withstand-voltage testing ramp-up and during
insulation-resistance testing delays. (However, it does not light during time testing
when insulation-resistance test termination mode is set to 0 [initial setting].)
The
DOWN
lamp lights during withstand-voltage testing ramp-down.
1. Press the
START
key when
READY
is lit.
The unit will change to the TEST status and a test will start.
TEST
and the
DANGER
lamp are lit in the TEST state.
2. In either of the cases below, the test will be terminated and
UPPER
,
LOWER
,or
FAIL
will light.
When performing a withstand-voltage test:
The output voltage doesn't reach the set test voltage value
±
5%.
The output voltage deviates from the test voltage value during the test
and doesn't return to the set value
±
1 dgt. within 5 seconds.
When performing an insulation-resistance test:
About 1 second after the test has started, the output voltage is still
lower than 1/2 of the set test voltage.
The test time has elapsed without the output voltage reaching a level
between 5% lower and 50% higher than the set test voltage value.
Output voltage during testing differs from the test voltage value and
does not fall within the range 80% to 150% of the voltage setting.
*See Section 3.4.1 / 4.4.1
3. To terminate the test, press the
STOP
key. The unit will immediately stop
outputting a voltage and switch to the READY state. In such a case, no
screening is conducted.
Optional Functions
The Hold function can be used to hold the value that was effective at the
time of forced termination of the test. (See Section 7.3)
If the
W
or
I
key is pressed when the Hold function is enabled, you can
view the next test result.
