The pickup coil While you can use your v.t.v.m. and r.f. probe for this purpose, the sensitive r.f. voltmeter probe described here is extremely convenient.Portable multimeter. Figure 13. Electronic multimeter. Figure 14. RF probe. Section III. using the proper meter, it is possible to compare accurately the voltages present and those that should be present. Usually, the ac ranges have a sensitivity  of the operating
