In the past two years FLUKE marketing team caused lots of confusion by releasing after the Wireless CNX series, their next wireless Fluke connect series.
Lots of wireless modules which was looking alike and even the master multimeter ( the one which the modules can connect with) it is looking alike too.
The significant information is that even if your own a Fluke CNX Bluetooth PC adapter this is not compatible with ir3000 FC Wireless Connector, and so if you make plan to use this with Fluke 189, 289 as Wireless KIT? This translate that total cost of ownership will include ir3000 FC Wireless Connector + pc3000 FC PC Adapter, and this is roughly a cost of 200$ retail.
This document bellow it will clear up the confusion for good.
