How to Select a Handheld DMM

That is RIGHT for You

Application Note

Introduction

Handheld digital multimeters (DMMs) are among the most widely used instru-

ments for installation, test, and repair of electrical equipment. However, the

variety of brands and DMM features can make it difficult to determine which

handheld DMM is best suited to your application needs. Selecting a handheld

with more capabilities than you need can mean spending more for equipment

than necessary, while selecting a device under-equipped for the application can

expose technicians to life-threatening electrical hazards.

To assist you in choosing a handheld DMM, this application note looks at some

of the device’s key attributes: handheld specifications, basic functionality, and

features targeted for specific industrial applications. It also provides information

on the design and features of Agilent handheld DMMs to guide you in your

selection process.
