SAFETY CHECK-OUT

After correcting the original service problem, perform the following safety check 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 as described below.

LEAKAGE TEST

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 microampers.). Leakage current can be measured by any one of three methods.

1. A commercial leakage tester , such as the Simpson 229 or RCA WT -540A. Follo w the manufacturers’ instructions to use these instruments.

2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job.

3. 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 lowvoltage scale. The Simpson 250 and Sanwa SH-63T rd ar e examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2 V A C range are suitable. (See Fig. A)

Procedure:

1. Connect the frequency counter to R813.

2. T urn the POWER switch ON, press VIDEO 1 and set the function to VIDEO 1. (The input signal set to OFF.)

3. Turn the POWER switch OFF, keep the BAND , depressed at the same time and then turn the POWER switch ON.

4. Check that the screen shown only the color bars, and then adjust CT802 so that the reading becomes 3.5796 MHz ± 10 kHz.

5. Adjust CT801 so that the right edge of the color bars on the screen comes within the frame.
