MM650 CAT IV True RMS Digital
Multimeter with LoZ

Introduction

The Triplett MM650 features True RMS measurements for more
accurate AC readings and a Low Z setting for eliminating false
readings caused by “ghost” voltages. Functions include AC/DC
voltage and current, resistance, continuity, capacitance, frequency,
duty cycle, temperature, and diode test. The MM650 also offers the
added convenience of a built-in LED flashlight. This meter is fully
