Fluke Connect-and-View™ triggering
with Auto Reading function using Fluke
IntellaSet™ technology gives you quick
access to the data you need.

Connect-and-View™
triggering for an instant,
stable display

Oscilloscope users know how
difficult triggering can be.
Using the wrong settings can
lead to unstable waveform
captures, and sometimes the
wrong measurement data.
Fluke’s unique Connect-and­View™ triggering technology
recognizes signal patterns, and
automatically sets up the correct
triggering to provide a stable,
reliable and repeatable display.
Connect-and-View™ triggering
is designed to work with virtu­ally any signal, including motor
drives and control signals—
without adjusting parameters,
or even touching a button.
Signal changes are instantly
recognized and settings are
automatically adjusted, provid­ing a stable display even when
measuring multiple test points
in quick succession.

IntellaSet™/AutoReading

The Auto Readings function
with Fluke IntellaSet™ technol­ogy uses proprietary algorithms
to intelligently analyze the
measured waveform and auto­matically displays the most
appropriate numerical measure­ments on screen, so you can get
the data you need easier than
ever before. As an example,
when the measured wave­form is a line voltage signal,
the Vrms and Hz readings
are automatically displayed,
whereas if the measured
waveform is a square wave, the
Vpeak-peak and Hz readings
are automatically displayed.
Using IntellaSet™ technology
in conjunction with Connect­and-View™ automatic triggering
you can be sure you’re seeing
not only the correct wave­form, but the appropriate
numerical reading as well. All
without touching a button.

Easily obtai n key power characteristics to validate a system
power.

Harmonics measurements

Harmonics are periodic distortions of voltage,
current, or power sine waves. Harmonics in
power distribution systems are often caused
by non-linear loads such as switched mode
dc power supplies and adjustable speed motor
drives. Harmonics can cause transformers,
conductors, and motors to overheat. In the
Harmonics function, the Test Tool measures
harmonics to the 51st. Related data such as dc
components, THD (Total Harmonic Distortion),
and K factor are measured to provide a com­plete insight in to the electrical state of health
of your loads.

Harmonic spectrum overview with cursors
to measure the distortion as a percentage
of the fundamental.

One test lead to measure multiple
electrical parameters

High frequency waveform, meter, capacitance and
resistance measurements as well as continuity
checks are all covered by single set of shielded
test leads. No time is wasted finding or swapping
leads.

Industrial equipment needs a reliable power supply to
operate properly, use the dual input to obtain key power
measurements.

For single phase or 3-phase balanced systems, the dual inputs
of the Industrial ScopeMeter® 120B Series can measure ac+dc
rms voltage on channel A and ac+dc rms current on channel
B. The Fluke 125B can then calculate; frequency, phase angle,
active power (kW), reactive power (VA or var), power factor (PF)
or displacement power factor (DPF) and can also calculate the
power values for a 3-phase system where all phases have equal
voltage and currents. This applies to both balanced system and
resistive loads.

Quickly step through recorded events
to identify and troubleshoot intermittent
faults.

Quickly understand industrial field bus

Automated industrial machinery
is harder than ever to trouble
shoot. It’s not enough to just
know where you have to test,
you also have to know what to
look for—and that can be hard
without baseline measurement
data or access to subject matter
experts. The Fluke Connect®
Assets wireless system of
software and wireless test tools
enables technicians to reduce
maintenance costs and increase
uptime with accurate equip­ment records and maintenance
data that is easy to interpret,
and share. Compare and
contrast test point measure­ment data and trends so you
can better understand signal
characteristics and changes
over time. And, by storing
maintenance data on the Fluke
Cloud™ you can enable team
members to access it from
wherever and whenever they
need to so you can get advice
or approvals in the field and
get your systems up and run­ning faster than ever before.

Use the comprehensive
recorder modes to help find
intermittent faults with ease

The toughest faults to find are
those that happen only once
in a while—intermittent events.
They can be caused by bad
connections, dust, dirt, corro­sion or simply broken wiring
or connectors. Other factors,
like line outages and sags or
the starting and stopping of
a motor, can also cause inter­mittent events resulting in
equipment shutdowns. When
these events happen, you may
not be around to see it. But,
your Fluke ScopeMeter® Test
Tool will. You can either plot the
minimum and maximum peak
measurement values or record
the waveform trace. And, with
expandable micro SD memory,
recording sessions can be done
for up to 14 days. This recorder
is even more powerful with
the addition of Recorder Event
Detect, which makes detect­ing and logging intermittent
faults easier than ever. Just set a
threshold on a meter reading or
scope trace and deviations are
tagged as unique events. You no
longer need to search through
masses of data to pinpoint faults,
and can quickly step from one
tagged event to the next, while
still having access to the full
data set.

Industrial Bus Health Test
verifies electrical signal
quality on industrial buses

Bus Health Test analyzes the
electrical signals on the indus­trial bus or network and gives
a clear “Good”, “Weak” or “Bad”
indication mark for each of the
relevant parameters, presented
next to the actual measurement
value. Measured values are
compared to standard values
based on the selected bus types
(CAN-bus, Profi-bus, Foundation
Field, RS-232 and many more),
or, unique reference values
can be set if different toler­ances are required. The Fluke
125B can validate the quality
of the electrical signals as soon
as they are passed along the
network, without looking at the
data content. Additionally, the
125B checks the signal levels
and speed, transition times and
distortion, and compares these
to the appropriate standards
to help you find errors such as
improper cable connections, bad
contacts, incorrect grounding or
improper terminators.
