Fluke 289 not quite sorted.

I believe you to be correct sir, but I can't find the culprit with the back of my finger.
When it works, it's pulling 18-20mA, but then shuts down after a minute or so, usually when menu hopping.
I'll get to the bottom of it if it kills you.
purp:
On one of the rare occasions that the meter was functional, I managed to do a 'reset to factory default' and it's been on for an hour now.
Looks like this may have been a software problem.
Anyway, I'm delighted to have a meter long lusted after.
The only downside is that it makes my hands look small..!!

Thanks for chiming in gents.

I was going to suggest that when I saw your post about it shutting down after menu hopping.  I'm glad you got it all sorted out.

I think 1.16 is the latest firmware for the 28x?  See

I spoke too soon.
It was working flawlessly for around eight hours and then died on me.
My work is still ahead.

I'll not attempt flashing the beast until it's 100% stable.
