Power Quality Logger
Introduction
The Fluke 1745 Power Quality Logger, see Figure 1, is a sophisticated, easyto-use, electrical power-recording device for the electrician or power-quality
specialist.
Note
This manual also refers to the 1745 Power Quality Logger simply as
“the Logger”.
The Logger conatins an automatically charged 8-hour UPS (uninterruptable
power supply) battery for long-term voltage interruption ride-through, and an
LCD status display to provide confidence in setup before you leave the Logger
in place to collect data.
You can power the logger in parallel with the test leads or through an outlet.
Adapter cords for both methods of power in the Logger are included as
standard equipment.
You’ll prepare the Logger for use with the included PQ Log software. You can
then connect the Logger to an electrical power-distribution network to log a
variety of power parameters, recorded as sequential averaged values over an
averaging period you can define. The Logger can measure up to three voltages
and four currents simultaneously.
Information and PC Software CD
The CD included with the Logger contains the PQ Log application software for
Windows, along with users manuals in multiple languages.
The PQ Log software prepares the Logger for use, and downloads data from
the Logger to a connected PC.You can then view the logged data in graphical
and tabular form, export it to a spreadsheet, or create reports for printing. For
details and instructions, see the PQ Log Users Manual on the CD.

Logger Power Supply
The Logger does not include a power switch, but turns on automatically
whenever its power supply leads are connected to a voltage in its allowed
range. You can plug the Logger’s power supply leads into a standard wall
outlet (using the included adapter cord), or you can connect them directly to
the power network under test (in parallel with the test leads) if there is no
convenient wall outlet (only if the voltage at the test leads is below 660V
RMS.)
Logging Functions
The Logger monitors power quality and locates disturbances in low and
medium voltage distribution networks. It measures up to 3 voltages and
4 currents. Logged values are saved in your choice of sequential averaging
periods. You graphically or numerically evaluated measured values with PQ
Log.
The Logger has two types of logging functions: logging function A
(Advanced) and logging function P (Power). Function A is the full set of
parameters, and function P provides logging capability optimized for load
studies and basic power logging. Function P contains every parameter in
Function A except voltage and current harmonics and interharmonics.
Logging function P allows longer logging periods because it does not save
harmonics values.
