Digital Multimeter

EM3701, Digital Multimeter

Introduction

This meter is a compact 3 1/2 digits digital multimeter for measuring DC and AC voltage, DC and AC current, resistance, diode, and continuity. In addition, squarewavesignal output is also provided. It features polarityindication, data hold, overrange indication, overloadprotection, automatic power-off, and etc. It is easy to operate and is an ideal test tool.
