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.
Features:
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
Specifications:
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 ]).
