Handling Precautions

3.6

Actions to Be Taken in Emergency

In case of an emergency (such as an electric shock accident or burning of the DUT),
take the following actions:

(a) Turn OFF the power switch of the tester.
(b) Disconnect the power cord of the tester from the AC line receptacle.

You may do either (a) or (b) 

fi

rst. But be sure to do both.

3.7

Breakdown

3.7.1

Stopping the Use of Broken Testers

If the tester behaves as indicated below, the tester may have broken down. The tester
may be in an extremely dangerous state in which the high voltage cannot be shut
down. If such behavior is observed, immediately turn OFF the power switch and
disconnect the power cord from the AC line receptacle. Never attempt to repair the
tester by yourself. Please contact Kikusui distributor/agent.

•

The DANGER lamp does not turn OFF even though you press the STOP
switch.

•

The DANGER lamp does not turn OFF but the pointer of the output volt-
meter is de

fl

ected indicating that the output voltage is being delivered.

In other cases in which the tester is not operating properly, there is a possibility that
the output voltage is delivered irrespective of your proper operating procedure. Stop
using the tester immediately.

3.7.2

DANGER Lamp

Continuing to use the tester when the DANGER lamp does not light up (due to a
failure of the lamp itself or other cause) when it should can lead to mistakes. This
constitutes an electric shock hazard. Immediately stop using the tester and contact
Kikusui distributor/agent for repair.
