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 (capac-

•

itance, 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, high­current environment.

CAT III Three-phase

distribution, including
single-phase
commercial lighting

CAT II Single-phase receptacle

connected loads

• Refers to the “origin of installation,” i.e.,
where low-voltage connection is made
to utility power

• Electricity meters, primary overcurrent
protection equipment

• Outside and service entrances, service
drop from pole to building, run between
meter and panel

• Overhead line to detached building,
underground line to well pump

• Equipment in fixed installations, such as
switchgear and polyphase motors

• Bus and feeders in industrial plants

• Feeders and short branch circuits,

distribution panel devices

• Lighting systems in larger buildings

• Appliance outlets with short connections

to service entrance

• Appliance, portable tools, and other
household and similar loads

• Outlet and long branch circuits
– Outlets at more than 10 meters

– Outlets at more that 20 meters

(30 feet) from CAT III source

Fluke 279 FC
Thermal Multimeter

Find. Repair.
Validate. Report.

The 279 FC is a full­featured digital multi­meter with integrated
thermal imaging and
is designed to increase
your productivity and
confidence. The thermal
multimeter helps you
find, repair, validate, and
report many electrical
issues quickly so that
you are confident prob­lems are solved.

Locate the problem
immediately

Thermal imaging mul­timeters are a first-line
troubleshooting tool for
electrical equipment that
can check hot spots on
high-voltage equipment
and transformers, detect
heating of fuses, wires,
insulators, connectors,
splices and switches.
Scanning with the 279
FC’s thermal imager
reveals many electrical
issues rapidly and from
a safe distance. By com­bining two tools into one,
the thermal multimeter
lightens the load and
increases productivity.

Expanded
functionality

Compatible with iFlex®
(a flexible current clamp)
to expand your measure­ment capabilities and
get into tight, hard to
reach spaces for current
measurement (up to 2500
A ac). The large full­color LCD screen makes
for easier and clearer
viewing of images and
readings. The 10 hour+
rechargeable battery
keeps you going all
day long under normal
conditions.

Communicate
your results

With built-in Fluke
Connect®, transmit
results wirelessly to a
smartphone and save
time on reporting to
validate work is com­plete. Troubleshoot better
by instantly trending
and monitoring mea­surements live on your
smartphone screen.
Create and email reports
right from the field.
