5、ltage drop across a resistor by means of a VOM or 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 of a pas- sive VOM that is suitable. Nearly all battery operated digital multim

6、eters that have a 2V AC range are suitable. (See Fig. A) Fig. A. Using an AC voltmeter to check AC leakage.

8、etal part having a return 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 or RCAWT-540A. Follow the manufacturers instructions to use these instruments. 2. A battery-operated AC
