Hi everyone,
I just spoiled myself a little and got a Fluke 289 even though it's actually far, far, far out of my league from a knowledge point of view. But I have a few good uses for it and overall it seemed like the best choice so that I'm limited by incompetence rather than equipment.

Also, there was a promo and I got it at a ridiculous price, I paid about US$850 with VAT and shipping and I got the TLK289 kit with leads and a bag. Considering the normal base cost of an 289 is about US$970 and the TLK289 kit is another US$200-250 here in Sweden I thought it was a steal.
Anyway. Since what I mainly do is tinker with Arduino based projects and some of them will be low powered battery type of projects where measuring an expected battery life is somewhat critical, I think I have a use for accurate current measurements coupled with the 289's datalogging capabilites. Being as I'm a big fan of Dave and his videos (along with Martin Lortons) was invaluable for me when choosing the right multimeter I obviously stumbled across the uCurrent Gold, which seems really nice.
I am however not sure what real world improvement there is in the uCurrent Gold over the 289 on it's own as it seems that the 289 has fairly good stats to begin with.
Can anyone with better understanding of this subject give me some kind of reference for how much inaccuracy the 289 is going to induce over the uCurrent Gold? Is it worth the AU$79 plus whatever shipping is (can't seem to find out without actually paying for the product) and then most likely another 25% VAT and US$14 to the postal services?
I can't seem to find the detailed specs for the 289, perhaps Fluke doesn't want them to be seen.

What I can find is that it is rated at a burden voltage of 1.8mV/mA for mA and 0.1mV/uA and an accuracy of 0.05% (I would assume +2 at least) for the 500 uA-range, although that could be blatant marketing from Flukes side as they had bundled all the DC current together.
Cheers
