Each set must be insulation tested after dismantling.The test is to be performed when the set has been re-assembled and is ready for delivery to the customer.

Make the insulation test as follows:

Short-circuit the two plug pins of the mains plug andconnect to one of tle terminals of the insulationtester,

Connect the other terminal of the insulation tester tothe chassis of the TP 1 socket (screen f pin 2).

NB!To aooid ruining the set, it is essential that bothtenninals of the insulatinn tester ale in really good,mecfumical contact.

Now slowly hrn the voltage control of the insulationtester until a voltage of 1.5 - 2 kV is obtained" Holdit there for 1 second, then slowly turn the voltagedown again

At no point during the testing procedure any flash.overs are permissible.
