• No more writing data down. Capture up to 65000
sets of min/max/avg readings over single or multiple
logging sessions using the recording capability.
Each reading and session is time stamped
• Avoid awkward or uncomfortable measurement
positions. Set up the measurement once, step
back and read it as many times as you want, when
you want
• Identify up to 10 placed modules with meter or PC
and choose only the ones you need
• View up to 10 live readings at once on a PC to get a
complete understanding of the situation
• Easily see backlit displays in dark or dimly lit work
environments
• Choose auto or manual ranging
• Use the optional TPak magnetic hanger for even
more hands-free working
• Integrated holster protects the meters, while probe
holders keep accessories organized
Safety
• Increase safety by taking readings in a separate
location than the point of measurement
• Fluke CNX meets Measurement Category 1000 V
CAT III and Category IV 600 V safety standards: AC
current clamp 600 V CAT III; AC Voltage Module and
iFlex Clamp Meters 600 V CAT IV / 1000 CAT III

Series Test Tools
The Fluke Wireless Team
The new Fluke wireless troubleshooting
team lets you see live measurements
from multiple modules simultaneously
and remotely on a single screen. This
customizable tool set, built with the
durability, reliability and quality you’ve come
to expect from Fluke tools, will change the
way you work.
Wireless multimeter displays readings
from up to three wireless modules, plus
the meter from up to 20 meters away. Add
a laptop and review ten measurements at
once.
Fluke CNX 3000 Series
• Digital Multimeter
• AC Voltage Module
• AC True-rms Current Clamp Module
• iFlex True-rms AC Current Clamp Module
• K-Type Temperature Module
• PC Adapter
Productivity
• Save money and time by taking multiple measure-
ments simultaneously
• Isolate intermittent events or record signal fluc-
tuations without even being there using the log
function on the modules
• Work with fewer interruptions by recording multiple
sessions before downloading. Data is saved to a PC
in .csv format (comma separated variable) file format
for easy viewing at your convenience
• Capture readings at different intervals, with user-set
recording intervals from one second to one hour
• Choose the module(s) that work best for your
applications
Convenience
• No more run-around. See up to four measurements
(DMM and 3 modules) on one screen, in one place
at the same time.
