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
