LEAKAGE The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis 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 RCA WT 540A Follow the manufacturers instructions to use these instruments A battery operated AC milliammeter The Data Precision 245 digital multimeter is suitable for this job Measuring the voltage drop across a resistor by means of a VOM or battery operated AC voltmeter The limit indication is 0 75 V so analog meters must have an accurate low voltage scale The Simpson 250 and Sanwa SH 63Trd are examples of a passive VOM that is suitable Nearly all battery operated digital multimeters that have a 2V AC range are suitable See Fig A To Exposed Metal Parts on Set AC Voltmeter 0 75 V Earth Ground Fig A Using an AC voltmeter to check AC leakage MODEL IDENTIFICATION BACK PANEL AEP UK models Canadian model US model Part No Part No CAUTION Danger of explosion if battery is incorrectly replaced Replace only with the same or equivalent type recommended by the manufacturer Discard used batteries according to the manufacturer s instructions ADVARSEL Lithiumbatteri Eksplosionsfare ved fejlagtig handtering Udskiftning ma kun ske
