23 For the U.S.A. and Canada SAFETY CHECK-OUT After correcting the original service problem, perform the following safety checks before releasing the set to the customer : Check the metal trim, metallized knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below. LEAKAGE TEST The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0. ma. Leakage current can be measured by any one of three methods.. A commercial leakage tester, such as the Simpson 9 or RCA WT-0A. Follow the manufacturers instructions to use these instruments.. A battery-operated AC milliammeter. The Data Precision digital multimeter is suitable for this job.. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The limit indication is 0.7 V, so analog meters must have an accurate lowvoltage scale. The Simpson 0 and Sanwa SH-6Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a V AC range are suitable. (See Fig. A) To Exposed Metal Parts on Set 0. µf. kz AC voltmeter (0.7V) Earth Ground Fig A.
