How to choose the best
DMM for your job
Choosing the right digital multimeter (DMM) requires thinking
about what you’ll be using it for.
Evaluate your basic measurement needs and job requirements
and then take a look at special
features/functions built into
many multimeters. Think about
whether you need to do basic
measurements, or if you need
the more advanced troubleshooting options offered by special
features.

The increased occurrence and
levels of transient overvoltages
in today’s power systems have
given rise to more stringent
safety standards for electrical
measurement equipment. Transients that ride on top of power
sources (mains, feeder or branch
circuits) can trigger a sequence
of events that may lead to serious
injury. Test equipment must be
designed to protect people working in this high-voltage, highcurrent environment.
