I've been trying to justify the extra £££'s the 289 commands over the 867s and to be honest apart from the obvious 289 logging and couple other things the 867s doesn't have so can't compete I've been struggling.
Tonight I found something!
The 289 measures the capacitance between the rows of my breadboard quite well where the 867s won't at all!
Well worth the extra couple hundred ££'s right??
