I've been eying that up, I think its about $130 for the cable and forms s/w.
Even for $130 they can go fuck themselves - I am not paying for what should be free.
Gonna make an opensource cable and free basic logging software (just acquiring into CSV file) someday.
Just another $0.02. I sincerely regret that I bough Fluke 189 instead of Fluke 87 V. It was a stupid idea. While basically not bad, 189 boots up for 3-5 seconds, which takes away all the fun debugging with it. Also, in most modes it has a stupid menu which you should navigate with cursor buttons - AND you have to look at screen at the time. No blind operation.
So I always get my trustworthy chinese Fluke 19B for all the basic work - I only power up 189 if I need mOhms/uV range.
And if someone is going to upgrade their Fluke 87V - forget it, unless you absolutely know what you are doing.
Bad Karma to Fluke. Bad, bad Fluke. Don't turn your multimeter into a handheld tablet.
