Final check after repair Final check after repair The fi nal check after repair, describes the activities that are needed to ensure the product

35、 will be returned in perfect condition to the customer. The contents are: - Insulation test / AC leakage test. - Check product information. - Restore the setup and check connections. - Final cleaning of the product. Insulation test Each HDR 1 must be insulation tested after having been dismantled. M

36、ake the test when the set has been reassembled and is 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. Con

37、nect the other terminal to ground on the aerial socket. NOTE! To avoid damaging the HDR 1 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 ac and max. 10mA is obtained. Maintain that vol

38、tage for one second, then slowly turn it down to 0 V ac again. Monitor information The scope of this check is, to ensure the following: - The product has maintained the correct identity. - The error code register is cleared. Procedure Enter Service menu A/V board H8 information. Check the serial num

39、ber is correct. Clear the error code. Select error code and press GO. Final check after repair 3.3 Customer setup Remember to inform the customer of any changed that has been made in the user setup, due to procedures in the service manual, such as Connections, Replay, Recording quality, etc. Restore
