Power Log
Introduction
Power Log is the PC software for Fluke models 345, 435, and 1735. The Fluke 434 also
uses Power Log if the 434 logger function is installed. These models are referred to
throughout this manual as “the instrument”. Power Log accepts data downloaded from an
instrument and is compatible with MS Windows®NT, 2000, and XP.
After transferring logged data to a PC for graphical and tabular evaluation, data may be
exported to a spreadsheet for generating and printing reports.
With Power Log, you can:
•Download recorded logged data to a PC
•Generate data tables
•View, print, and export time plots of all channels
•Perform harmonic studies
•Print tables, graphs, and comprehensive, formatted reports
•Export data for manipulation in other programs (Excel, for example)
This manual provides instruction for installing and using the software, as well as limited
instruction for connecting to Fluke power quality instruments. Brief introductions to
opening, viewing, filtering, and exporting data guide users through most of the features of
Power Log.
Logging Parainstruments
Log function parainstruments available for viewing and analyzing using Power Log
depend on which instrument you are using. This manual uses examples generated by the
Fluke 345, 435, and 1735 instruments.

Insert the CD-ROM for your instrument. The installation should start automatically. If
not, run the “launch.exe” program on the CD-ROM. Follow the instructions on the screen
to install Power Log in your choice of languages. The 434 and 435 use “autorun.exe” to
install Power Log.
Note
If you are missing the CD-ROM, install the Power Log software from the
Fluke website.
The manual and all application software installs in the application directory, with a
shortcut in the programs menu. Power Log installs a quick launch shortcut if you make
that selection during the installation process.
Installing from Fluke Website
Installing from the website requires a short registration process before redirecting you to
the product download page. Navigate to the Fluke website at www.fluke.com and install
using the on-screen instructions available from the product page for your instrument.
Available Language Support
Power Log installs site support in all available languages. Users can view the Fluke
website in the language of their choice based on their computer’s operating system (OS)
settings. For example, a user with their OS setting fixed for Germany will automatically
see the support website in German.

WX Warning
To avoid electrical shock or damage to the equipment, and
before making any connections to the instrument, read and
follow the safety warnings and cautions included in the
instrument Users Manual.
Regardless of the instrument used, install the Power Log software before connecting to
the instrument. The 345, 435 and 1735 instruments use either the RS232 serial or USB
interface to connect directly to a PC.
Connect the instrument to a power source and turn it on before starting the Power Log
software.
Refer to the manual provided with your instrument for any questions not answered in this
manual.
Connecting a 345
Connect a 345 to the PC using a standard USB cable supplied with the instrument. The
USB port is located on the right side of the instrument.
Connecting a 435
Use the optical RS232 interface for connecting the 435 to a PC or printer.
Use the optical interface cable (model OC4USB) provided with the 435 to make the

Harmonics Tab
Harmonics are periodic distortions of voltage, current, or power sine waves. Each
waveform can be considered as a combination of various sine waves with different
frequencies and magnitudes.
Harmonics are often caused by non-linear loads such as DC power supplies in computers
and other adjustable motor drives, resulting in overheating transformers and conductors.
The harmonics timeplot offers two options for the display. The histogram displays the
data in a bar graph, with the % of the fundamental (50 or 60 Hz) on the left side
(vertical, or Y axis) and harmonic order on the X axis (horizontal), as shown in Figure 6.

Select the Time evolution radio button to change the display to a graph displaying the
time along the X (vertical) axis, as shown in the example data in Figure 6.
Frequency/Unbalance Tab
Unbalance displays the voltage unbalance (%) in a system. This is an important
measurement in the case of electric motors, which will run hotter when voltage is not
balanced. The method of calculation used is the ratio of positive-sequence symmetrical
components divided by negative sequence components. This is the measurement method
defined by the international standard IEC 61000-4-30.
Figure 8 shows the display indicating both the time plot and legend for the recorded
information.

Power Tab
The Power tab allows the user to filter the information using the checkboxes at the top of
the display window. In the example below, the Y axis shows the Total power (kW,
KVAR, and three phases). The X or horizontal axis shows the time data. Visible in Figure
9, a legend explains the colors used in the graph to distinguish between Active and
Reactive power.
