• Power quality that meets the standard:
All measurements comply with IEC61000-4-30
standards for correct evaluation of all measured
values including voltage, current, power, har-
monics, fl icker etc.
• Quick and reliable confi guration: PDA wire-
less “front panel interface” provides the ability
to verify setup without a laptop along with a
window into what the instrument is recording,
even in awkward test locations.
• Threshold-free setup: Apply thresholds after
data is collected with Fluke Power Analyze
Software so there is no need to worry about
missed information due to incorrect set-up.
• Captures everything: Cross-channel and current
triggering capture every measurement, on every
channel, every time.
Capture every measurement, every event,
on every cycle, all the time with the Fluke
1750 Power Recorder. Outstanding accuracy
and resolution provide complete visibility into
your installation or distribution system.

2 Fluke Corporation Fluke 1750 Three-Phase Power Recorder
Applications
Long-term analysis: Uncover hard-to-fi nd or
intermittent issues; monitor critical equipment,
capturing power quality events to correlate with
equipment malfunction
Power quality surveys: Quantify power quality
throughout a facility, documenting results with
professional reports
Quality of service compliance: Validate incoming
power quality at the service entrance
Equipment Installation/Commissioning: Bench-
mark power system prior to install to insure quality
of service
Easy to use
The recorder automatically detects, scales, and
powers current probes without needing batteries.
Requiring only single-lead voltage connections
enables safe and quick setups. Once power is
applied the instrument automatically begins record-
ing and LEDs give you assurance that the recorder
is powered up and signals are within range – no
more uncertainty that data is being recorded. The
Fluke 1750 has an exclusive capture algorithm
which makes certain all events are captured with-
out the tedious setups and blind spots associated
with threshold driven equipment.
The PDA wirelessly interfaces with the recorder,
allowing quick setup and verifi cation with wave-
form displays, meter screens, and phasor diagrams.
The built-in wireless technology allows you to
control multiple instruments from a distance easily,
without the need for a laptop computer (laptops can
also be used when desired).
View measurements real-time with
wireless PDA interface.
Configurations are simple with wiring
diagrams to guide you.
No need to reconnect wires—swap channels
internally using the PDA interface.

CAT IV rating and, therefore, can be used for most power
connections and for all outlets in a low-voltage power
distribution system.
View data the way you want
The new Fluke Power Analyze software revolu-
tionizes your ability to analyze data. No need to
worry about thresholds—with Fluke Power Ana-
lyze, thresholds can be modifi ed after the data is
recorded! And the easy-to-use user interface will
display voltage as a phase-to-phase or phase-to-
neutral reading.
Apply thresholds to data after collection using a variety of
standard or customized templates.
