20、 After correcting the original service problem, perform thefollowing 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.LEAKAGE The AC leakage fro

21、m any exposed metal part to earth groundand from all exposed metal parts to any exposed metal part havinga 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 RCAWT-540A. Fol

22、low 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 aVOM or battery-operated AC voltmeter. The “limit” indicationis 0.75 V, so ana

23、log meters must have an accurate low-voltagescale. The Simpson 250 and Sanwa SH-63Trd are examples ofa passive VOM that is suitable. Nearly all battery operateddigital multimeters that have a 2V AC range are suitable. (SeeFig. A)Earth GroundACvoltmeter(0.75V)1.5k0.15FFig. A. Using an AC voltmeter to

When the DSPtest is activated, the test data is output from the DSP (IC1401:CXD2712R) of the DIGITAL board and is written in the RAM(IC1402:

38、IDT71V016S). When the test data is read from the RAMby the DSP, the data output must be equivalent to the originaldata. If they disagree, an error is triggered. Errors can be causedby the broken data line or defective soldering.* ProcedureWhile pressing the SETUP, LEVEL and SUR buttons, press thePOW
