ELECTRICAL PARTS LIST .19SAFETY CHECK-OUTAfter correcting the original service problem, perform the follow-ing safety checks before releasing the 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 having 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 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 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.

Leave for another 30 minutes if the adjustment control has beenrotated.5. Measure the voltage again and check that it is within the adjust-ing value. If outside, repeat from step 3 again.6. Be sure to perform aging for more than 30 minutes if the adjust-ment control has been rotated. Finally check the voltage beforeending the adjustment.THIS NOTE IS COMMON FOR PRINTED WIRINGBOARDS AND SCHEMATIC DIAGRAMS.(In addition to this, the necessary note is printedin each block.)For schematic diagrams.Note: All capacitors are in F unless otherwise noted. pF: F50 WV or less are not indicated except for electrolyticsand tantalums.
