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 aVOM or battery-operated AC voltmeter. The “limit” indica-tion is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex-amples of a passive VOM that is suitable. Nearly all batteryoperated digital multimeters that have a 2 V AC range are suit-able. (See Fig. A)Fig. A. Using an AC voltmeter to check AC leakage.4STR-DE697TABLE OF CONTENTS1.
