Check leakage as described below. LEAKAGE 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.. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow 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 low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable. (See Fig. A) HOW TO CHANGE THE CERAMIC FILTER This model is used two ceramic filters of CF2 and CF3. You must use same type of color marked ceramic filters in order to meet same specifications. Therefore, the ceramic filter must change two pieces together since it's supply two pieces in package as a spare parts. mark Mark Center mark frequency CF2 CF3 no mark blue orange black white 0.70MHz 0.67MHz 0.73MHz 0.64MHz 0.76MHz 0.5µF To Exposed Metal Parts on Set.5kΩ AC voltmeter (0.75V) Earth Ground Fig. A.
