26、:Check the antenna terminals, metal trim, “metallized” knobs,screws, and all other exposed metal parts for AC leakage.Check leakage as described 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 ch

27、assis, must not exceed 0.5 mA (500 microamperes).Leakage current can be measured by any one of three methods.1.A commercial leakage tester, such as the Simpson 229 or RCAWT-540A. Follow the manufacturers instructions to use theseinstruments.2.A battery-operated AC milliammeter. The Data Precision 24

28、5digital 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” indica-tion is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex-amples of a passive VO
