4、 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.LEAKAGEThe AC leakage from any exposed metal part to earth Ground andfrom all exposed metal parts to any exposed metal part havin

5、g areturn to chassis, must not exceed 0.5 mA (500 microampers). Leak-age 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

6、 Data Precision 245digital multimeter is suitable for this job.3. Measuring the voltage drop across a resistor by means of a VOMor battery-operated AC voltmeter. The “limit” indication is 0.75V, so analog meters must have an accurate low-voltage scale.The Simpson 250 and Sanwa SH-63Trd are examples

7、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.
