  • Work Faster, Safer and Easier with CNX Wireless Test Tools

    Fluke's CNX Wireless Test Tools put tools, not your body, near live electrical panels. It's simple. Connect the remote modules, whether they are voltage modules, current clamps, flexible current loops or thermometers, and read the results on the CNX 3000 Wireless Multimeter from a safe distance. You can display the meter measurement, plus readings from up to 3 wireless modules.

    Don't Get Bogged Down While Isolating Intermittent Electrical Faults

    Timing is everything when trying to find an intermittent problem and the hard part is, it doesn't always show up when you have your meter connected. We've solved that problem with CNX – leave your CNX remote modules connected to log measurements and walk away to address other issues. You can then download the data for further analysis.

    Work Safely Near Electrical Panels While Wearing Less PPE

    Personal protective equipment (PPE) can save your life, but it's bulky, hot and hard to work in. With CNX, there's no need to work in front of live open panels or moving/hazardous machinery.

    Picture having the ability to access live readings without being exposed to the live panel. It's easy. Just deenergize the cabinet, open the panel while wearing PPE and connect your CNX modules. Close the cabinet, reenergize and let the CNX multimeter work, reducing the risk of arc flash by separating yourself from hazardous measurement situations.

    Testing 3-Phase is Now Faster and Cheaper

    When your cabinet is deenergized, attach a CNX current clamp to each phase. Close, reenergize and start taking readings. What used to take hours and use costly equipment can be done in minutes with an affordable CNX wireless system.

    Take 3-Phase Measurements in 1/3 the Time. Add your laptop and go from logging to analysis and diagnosis

    You can solve problems faster by seeing live measurements from multiple test points on a single screen. With a CNX wireless test tool, you can:

    • Take 3-phase measurements in 1/3 the time
    • Add your laptop and go from logging to analysis and diagnosis
    • Record over time using the CNX wireless modules and monitor circuit load changes for an hour, a shift or a week
    • Use the CNX wireless USB adapter to collect logged data from remote modules by walking past a working module and downloading logged data
    • Perform for analysis with your PC and the CNX wireless test tool software. View data or graphs to see problems easily on the computer display
  • The CNX 3000 Wireless 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.

  • 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 ]).
