Ryobi RP4020 Digital Multimeter Review
This is by far the most sophisticated of the tools available currently in the Tek4 lineup. The Professional Digital Multimeter (RP4020) can measure AC/DC current and voltage, resistance, capacitance, and can check the forward voltage drop of a diode. It can test for continuity and has an internal speaker to give tones when buttons are pressed (and to indicate continuity). The voltmeter adheres to the Tek4 gray/green styling and includes an aluminum-style faceplate that is inset into the front of the unit, surrounding the mode selection dial, LCD screen and buttons. On the back side, the Tek4 Digital Multimeter sports a kickstand and a flip out “Convenience Hook” that lets you hand the meter off of conduit or any other material with a slight lip. We also enjoyed the built in probe holders, which secured the probes perfectly when they were wrapped vertically around the entire meter and left connected.
