The “ limit” indication is0.75V, so analog meters must have an accurate low-voltage scale.The Simpson 250 and Sanwa SH-63Trd are examples of a pas-sive VOM that is suitable. Nearly all battery operated digitalmultimeters that have a 2V AC range are suitable. (See Fig. A) Fig. A. Using an AC voltmeter to check AC leakage.Earth GroundTo Exposed Metal Parts on Set1.5k0.15FACvoltmeter(0.75V)SAFETY CHECK-OUTAfter correcting the original service problem, perform the follow-ing safety check 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. Check leakage asdescribed below.LEAKAGE TESTThe AC leakage from any exposed metal part to earth ground andfrom all exposed metal parts to any exposed metal part having areturn to chassis, must not exceed 0.5mA (500 microampers).Leakage current can be measured by any one of three methods.1. A commercial leakage tester, such as the Simpson 229 orRCAWT-540A. Follow the manufacturers instructions to usethese instruments.2. A battery-operated AC milliammeter. The Data Precision 245digital multimeter is suitable for this job.SAFETY-RELATED COMPONENT WARNING!COMPONENTS IDENTIFIED BY MARK ! OR DOTTED LINE WITHMARK !
