The CNX V3000 AC Wireless Voltage Module lets you work on electrical panels faster, safer and easier than ever before. De-energize the cabinet. Connect one or more CNX v3000 AC Wireless Voltage Modules. Close the cabinet and reenergize. Now you can view measurements from up to 20 meters away on the CNX Wireless Multimeter. Measuring three-phase systems has never been faster or easier. Plus, no more writing down data as the CNX v3000 Voltage 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 v3000 AC Wireless Voltage Module provides:- True RMS AC voltage measurements to 1000V- ±1% accuracy to 500 Hz, ± 2% accuracy to 1 kHz- Memory recording up to 65,000 readings- Backlit LCD display- CAT IV 600 V, CAT III 1000 V; IP42The CNX wireless system can track up to 10 measurement modules simultaneously, with results sent to a PC for detailed analysis.
