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.
Factors to consider:
Your work environment (voltage
•
level, types of equipment, types
of measurements, applications)
Specialty features/functions
•
(capacitance, frequency, temperature, non-contact voltage,
low impedance mode, min-max
record, data logging, trending)
Resolution and accuracy
•
(6,000, 20,000, or 50,000
count resolution)
Safety
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, high-current
environment.

• Equipment connected to (source) circuits in which

an appropriately low level

a high-winding resistance transformer, such as the
high-voltage section of a copier
• Appliance, portable tools, and other household
and similar loads
• Outlet and long branch circuits
• Outlets at more than 10 meters (30 feet) from
CAT III source
• Outlets more than 20 meters (60 feet) from

• Electricity meters, primary overcurrent protection
equipment

pole to building, run between meter and panel

line to well pump
