3 ST-D075 Ver. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat. SAFTY HK-OUT After correcting the original service problem, perform the following safety check before releasing the set to the customer: heck the antenna terminals, metal trim, metallized knobs, screws, and all other exposed metal parts for A leakage. heck leakage as described below. AKAG TST The A 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.). eakage current can be measured by any one of three methods.. A commercial leakage tester, such as the Simpson 9 or A WT-540A. Follow the manufacturers instructions to use these instruments.. A battery-operated A milliammeter. The Data Precision 45 digital multimeter is suitable for this job.. Measuring the voltage drop across a resistor by means of a VOM or battery-operated A voltmeter. The limit indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 50 and Sanwa SH-6Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a V A range are suitable. (See Fig. A) 0.5 µf Fig. A.
