The CNX 3000 Wireless True-RMS Multimeter

With the CNX 3000 Wireless True-RMS Multimeter, you see live measurements from multiple modules simultaneously and remotely on a single screen. The CNX 3000 Wireless Multimeter displays the meter measurement, plus readings from up to 3 wireless modules, as far as 20 meters away. By seeing multiple readings at the same time, troubleshooters can see cause and effect, interactions between inputs/outputs or other measurement points, simultaneously and remotely.
If more than three readings are required from more modules, add an optional PC adapter to your laptop for real time viewing of up to 10 modules.
The CNX 3000 Wireless True-RMS Multimeter has all the essentials for convenient test and measurement troubleshooting.
  • AC and DC voltage measurements to 1000V
  • AC and DC current with 0.01 mA resolution
  • Continuity, resistance, diode test, capacitance and frequency measurements
  • MIN/MAX Recording
  • CAT III 1000 V, Cat IV 600 V; IP54
Plus, the CNX wireless enabled modules measure AC voltage, AC current and temperature, which display on the CNX Wireless Multimeter. Choose a standard clamp or flexible clamp to measure AC current. Mix and match modules to suit your unique measurement needs. Read the primary measurement on the main display, and up to three modules at any one time. Modules are available separately or as part of CNX kits.

About the Fluke CNX 3000 Series of Products:

Fluke CNX wireless test tools work together to help you solve problems faster. With the CNX team, measurements are:
  • Remote
  • Simultaneous
  • Recordable
The new Fluke wireless troubleshooting team lets you see live measurements from multiple modules simultaneously and remotely on a single screen. This customizabletool set, built with the durability, reliability and quality you expect from Fluke tools, will change the way you work.
The wireless multimeter displays readings from up to 3 wireless modules, plus the meter. The laptop displays readings from up to 10 modules. Both from up to 20 meters away!
Wireless enabled modules measure AC voltage, temperature and AC current. Choose a standard true-rms clamp or flexible true-rms clamp to measure AC current. Mix and match modules to suit your unique measurement needs.

  • Capture up to 65,000 sets of min/max/avg readings over single to multiple logging sessions using the recording capability

No more waiting around
  • Save time and money by takingmultiple measurements simultaneously
  • Isolate intermittent events orrecord signal fluctuations withouteven being there using thelog function on the modules

No more uncomfortable positions
  • Set up the measurement once,step back and read it as manytimes as you want, when youwant, from where you want.
  • Increase safety by takingreadings in a separate locationfrom the point of measurement
  • Fluke CNX meets measurementCategory 1000 V CAT III andCategory IV 600 V safetystandards

Fluke CNX 3000 Series Key Features:

Productivity:
  • Save money and time by taking multiple measurements simultaneously
  • Isolate intermittent events or record signal fluctuations 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.
  • 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
For all specifications: accuracy is specified for one year after calibration, at operating temperatures of 18 °C to 28 °C, with relative humidity at 0 % to 90 %. Accuracy specifications take the form of ± ([ % of Reading ] + [ Number of least significant digits ]).
