Fluke 345
Power Quality Clamp Meter
With a bright color display to analyze the harmonic
spectrum, a low-pass filter to remove high frequency noise,
and a high EMC immunity design, the Fluke 345 is ideal for
measurements on switching loads such as variable frequency
drives, electronic lighting and UPS systems. Additionally, the
Hall Effect measurement system makes measurement of dc
current possible without the need to break the circuit, and
the internal memory enables long-term logging for analysis of
trends or intermittent problems.
The ideal meter for commissioning and
troubleshooting modern electrical loads

2 Fluke Corporation Fluke 345 Power Quality Clamp Meter
Log measured parameters
All voltage, current, power, and harmonic measurements
can be logged for minutes, hours, or months. Measurement
averaging periods from 1 second to 15 minutes can be selected
depending on the application.
Measured parameters can be logged into three separate
recording memory areas. If longer recordings are required, the
three areas may be combined into one. Stored measurements
can be recalled and displayed on-screen in normal screen
format or downloaded using the Power Log software package.
Applications
Set up and troubleshoot variable frequency drives
and UPS systems - Verify correct operation by
measuring key parameters
Harmonics measurements - Uncover harmonic issues
that can damage or disrupt critical equipment
Inrush capture - Check start-up current where spurious
resets or nuisance circuit breaker tripping occurs
Load studies - Verify electrical system capacity
before adding loads

3 Fluke Corporation Fluke 345 Power Quality Clamp Meter
Flexible and easy to use
The 345 measures a wide range of electrical parameters and
can be used for many applications in today’s modern electrical
environment. Measuring mode is selected by a simple turn of
the rotary switch and the large color display presents data in
a clear, easy-to-understand way.
By default the display will show the most common
measurements, in very large format. If more detailed views
are required they are available with the press
of a single key (up to six measurements at once).

function, or copy and paste images into report
document manually.
•Easy-to-use tabbed window format allows
quick data evaluation.
•One-step download and display capability
•Waveform, harmonics, and trend download
•Simple data export to other applications
Inrush current
Diagnose equipment start-ups with the inrush current mode.
A current trigger level is set prior to recording. Once the level
has been exceeded, the meter will begin capture. Recordings
from 3 seconds to 300 seconds may be captured, and up to
1000 inrush events may be stored in the instruments memory.
Screen captures and data logging
Any measurement can be stored in memory for later viewing,
or downloaded to a PC. Simply press ‘SAVE’ to capture the
active screen to memory – up to 50 screen shots can be
saved for quick and simple documentation. Additionally, over
150,000 individual measurements can be logged for later
review on the display or on a PC using Power Log software.
