The Fluke FLK-CNX 3000 Wireless Multimeter is the captain of the Fluke wireless team. With the CNX 3000 Wireless Multimeter, you see live measurements from multiple modules simultaneously and remotely on a single screen. The Fluke CNX3000 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.
