DESCRIPTION OF FRONT AND REAR PANEL ITEMS
33
[15] INDICATOR LAMPS
• AUTO TEST
Identi
fi
es between automatic test and single test. The lamp illuminates when in the automatic
test mode. When in the single test mode, either the ACW TEST lamp or the IR TEST lamp
illuminates.
• ACW TEST
Illuminates when in the withstanding voltage test mode.
• 2.5kV/5kV
Indicate the output voltage range being used for withstanding voltage test.
• IR TEST
Illuminates when in the insulation resistance test mode.
• 500V/1000V
Indicate the test voltage being used for insulation resistance test.
• PASS/FAIL
Indicate the test result. If the result of PASS-FAIL judgement is PASS, the PASS lamp illumi-
nates; if it is FAIL, the FAIL lamp illuminates. The FAIL lamp illuminates continuously; the
PASS lamp illuminates only for about 50ms.
However, at the PASS HOLD of TEST MODE switch on the rear panel is OFF. For details,
refer to "3.7 Special Test Modes" on page 26.
•
When no timer is used in the single test mode, the PASS judgement is not done.
• PROTECTION
When in any of the following cases, the protective circuit trips, the output is cutoff and the
lamp illuminates. (When this has occurred, remove the cause of the trip and then press the
STOP switch to reset the Tester.)
1.
When the RANGE 2.5kV/5kV switches of withstanding voltage tester are changed.
2.
When the IR TEST VOLTAGE 500V/1000V switches are changed.
3.
When the FUNCTION switches are changed. When two or more switches are in the
pushed-in state (
) or all switches are in the pushed-out state (
).
4.
When the REMOTE CONTROL connector is disconnected and then connected. (How-
ever, the lamp does not light when a connector which meets the requirements of reset con-
dition is connected without the FAIL ALARM of the SPECIAL TEST MODE switch ON
state).
5.
When the interlock terminals are made open.
6.
When the POWER switch is turned on again immediately after turning it off.
7.
When all of the CUTOFF CURRENT switches are set in the pushed-out state or set at 108
mA or more.
8.
When both withstanding voltage tester and insulation resistance tester are operated at the
same time due to a failure of the Tester.
•
If the lamp does not go off even when you have eliminated the cause of the trip to
the PROTECTION state and have pressed the STOP switch, the most probable
cause is a failure of the Tester. Immediately stop using the Tester.
[16] OUTPUT HIGH VOLTAGE (HIGH VOLTAGE terminal)
The hot line of the test voltage.
