samlet og klar til udlevering til kunden
Isolationstesten udfores pi falgende mide:
De to stikben pi netstikket kortsluttes og tilsluttes en
af terminalerne pa isolationstesterel
Den anden terminal fra isolationstesteren tilsluttes

OBS!
For at undgd beshadigelsel bd appalatet er det ligtigt,
at begge isolationstesterens terminaler har airkelig god
hontakt.
Der drejes nu langsomt med spandingsreguleringen

er opn6et Her skal den holdes i 1 sekund, derefter
drejes der langsomt ned for spandingen igen

INSULATION TEST

connect to one of tle terminals of the insulation
tester,
Connect the other terminal of the insulation tester to
the chassis of the TP 1 socket (screen f pin 2).
NB!
To aooid ruining the set, it is essential that both
tenninals of the insulatinn tester ale in really good,
mecfumical contact.
Now slowly hrn the voltage control of the insulation
tester until a voltage of 1.5 - 2 kV is obtained" Hold
it there for 1 second, then slowly turn the voltage
down again
At no point during the testing procedure any flash.
