The CNX 3000 Wireless Multimeter has all the essentials for convenient test and measurement troubleshooting.
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 ]).
