The Model RF241 RF Probe is designed to operate with 10 megohm input digital multimeters. The output of the RF Probe connects to the meter through the RF probe banana plugs. The probe converts AC signals in the RF range to equivalent DC levels for measurement by the meter. The probe is designed principally for use on the 20VDC range. The probe is peak-sensing, and the readout is in equivalent RMS volts (1 VRMS = 1 VDC).
