Fluke CNX-A3000 - AC Wireless Current Clamp Module
The CNX a3000 AC Wireless Current Clamp Module is part of the Fluke team of wireless troubleshooting tools.
Connect the CNX a3000 AC Wireless Current Clamp Module to your test point, and view the results up to 20 meters away on the CNX Wireless Multimeter. You’ll save time, with less run-around collecting multiple measurements. Use multiple modules for measurements on three-phase systems. Or use as a stand-alone measurement tool or combine with other CNX modules as a system for multiple measurements. From short distances, you can even view readings from modules through closed electrical panels. Plus no more writing down data as the CNX a3000 current module captures up to 65,000 sets of time stamped min/max/avg readings, using the optional PC adapter. CNX wireless test tools also offer increased safety by letting you view readings in a separate location from the test point. Now you can take readings on moving machinery, with only the measurement module in harm’s way.
The CNX a3000 AC Wireless Current Clamp Module provides:
- True-RMS AC current measurements to 400 A
- 2% accuracy to 100 Hz, 2-1/2% accuracy to 500 Hz
- Memory recording up to 65,000 readings
- Backlit LCD display
- CAT III 600 V; IP42
Using the optional PC adapter, the CNX wireless troubleshooting system can track up to 10 measurement modules simultaneously, with results sent to a PC for further analysis.
