Insulation test 5.
INSULATION TEST
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 and connect one of the terminals of the insulation tester. Connect the other
terminal of the insulation tester to the chassis of the 8-pin DIN socket.
N.B.!
To avoid ruining the set, it is esential that both insulator test terminals are in really
good mechanical contact.
Now turn slowly the voltage control of the insulation tester until a voltage of .3kV
is obtained. Hold it there for second, then turn slowly the voltage down again.
At no point during the testing procedure any flash-overs are permissible.
