SAFETY CHECK-OUT After cor recting the original service problem, perfor m the follow- ing safety checks before releasing the set to the customer: Check the antenna ter minals, metal trim, metallized knobs, screws, and all other e xposed metal par ts for AC leakag e. Check leaka ge as descr ibed belo w. LEAKA GE The AC leakag e fr om an y exposed metal part to earth Gr ound and from all e xposed metal parts to any e xposed metal part having a r eturn to c hassis, must not exceed 0.5 mA (500 micr oampers). Leak- a g e current can be measured by an y one of three methods. 1. A commercial leaka ge tester , such as the Simpson 229 or RCA WT -540A. F ollow the manuf acturers instructions to use these instruments. 2. A ba ttery-opera ted AC milliammeter . The Data Precision 245 digital multimeter is suitab le for this job. 3. Measuring the v oltage drop across a r esistor by means of a VOM or battery-oper ated AC v oltmeter . The limit indication is 0.75 V , so analog meters must ha ve an accur ate low-voltage scale . The Simpson 250 and Sanw a SH-63Trd are examples of a pas- si ve V OM that is suita ble. Nearly all battery operated digital multimeters tha t have a 2V AC range are suitab le. (See Fig. A) Fig. A.
