6.5.1 Executing a Test
DANGER
To avoid electric shock, 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).
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
ke
y
on the front
p
anel of the unit and the start si
g
nal for the external I/O.
NOTE
In addition to using the
STOP
key on the unit, a stop can be forced using the
STOP
key on the remote-control box or by using a STOP signal via external
input/output.
If each test condition is set as specified below, the test is conducted up to the step
immediately prior to reaching that condition, and the test is terminated.
Lower-limit value ≧ upper-limit value, Delay time ≧ test time,
Test-voltage value > output-voltage restricting value
The step number displayed at this time is that in which the test is terminated. The
step in which any of the above settings is recognized is that following the step
number displayed. When any of the above settings is recognized in step 1, the file
number is displayed instead of the step number, and the program test does not
start.
1. Press the
START
key when
READY
is lit in the program mode.
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)
During the hold state, the result of the terminated test can be displayed
using the / keys.
