3、ter correcting the original service problem, perform thefollowing safety checks before releasing the set to the customer:Check the antenna terminals, metal trim, “metallized” knobs,screws, and all other exposed metal parts for AC leakage. Checkleakage as described below.LEAKAGEThe AC leakage from an

4、y exposed metal part to earth ground andfrom all exposed metal parts to any exposed metal part having areturn to chassis, must not exceed 0.5 mA (500 microampers).Leakage current can be measured by any one of three methods.1. A commercial leakage tester, such as the Simpson 229 orRCA WT-540A. Follow

5、 the manufacturers instructions touse these instruments.2. A battery-operated AC milliammeter. The Data Precision 245digital multimeter is suitable for this job.3. Measuring the voltage drop across a resistor by means of aVOM or battery-operated AC voltmeter. The “limit”indication is 0.75 V, so anal

6、og meters must have an accuratelow-voltage scale. The Simpson 250 and Sanwa SH-63Trdare examples of a passive VOM that is suitable. Nearly allbattery operated digital multimeters that have a 2V AC rangeare suitable. (See Fig. A)Fig. A. Using an AC voltmeter to check AC leakage.To Exposed MetalParts
