Insulation test
Each set must be insulation tested after having been dismantled. Make the test
when the set is reassembled and ready to be returned to the customer.
Flashovers must not occur during the testing procedure!
Make the insulation test as follows:
Short-circuit the two pins of the mains plug and connect them to one of the
terminals of the insulation tester. Connect the other terminal to ground on the
aerial socket.
! To avoid damaging the set, it is essential that both terminals of the insulation
tester have good contact.
Slowly turn the voltage control of the insulation tester until a voltage of 2.5 kV
and max. 10 mA is obtained. Maintain that voltage for one second, then slowly
turn it down again.
