I took a look at the UT61E schematic and I can't spot any trim pots that would affect the voltage off the shunts.
However, I do see a 10K pot in line with the ohms voltage sense (VR3). Not sure how much effect that would have on a high impedance input, but it may tweak the ohms readings?
Be careful with your adjustments, you don't want to make it worse. :)

Mmmh, quick check on ebay shows they go for < $60 these days. Is the UT61E still the budget model to go for, or are there other nice deals to be aware of? I noticed the Digitek DT-2843R and Digitek DT-4000ZC being mentioned as well, but those don't quite have the resolution of the UT61E...

Still the cheapest option for a new sturdy 4 1/2 digit TRMS meter with autoranging. It is not a perfect meter by any means, but quite usable and probably the best value for a hobbyist on a budget.

I agree. Very good meter for the money. I did very careful research before I purchase it. I was not sure that this time around in returning to play with EE if my interest would not fizzle out as it did the last couple of times, so I was not willing to spend a lot of money with a new meter. I went the low cost route.
Having own the UT61E for a year now, I can say I am very pleased with it. I would have like it had it been say 60,000 count, twice as accurate, backlid, auto-off... etc, etc, etc. But that would have been 3x 4x or 10x what I was would have to spend.
Good value for the money is important in my decision. My diddling around requires nothing more that a percent or two accuracy. This far exceeded my need and at a very low cost. So in my case, I am very pleased with it.

Thanks! Looks like the UT61E is the one to go for. Or rather, it was the one to go for right now, and has become the one to maybe go for in the future. It's bloody typical. You look for a used 5 1/2 digit meter for quite some time, cannot find it for a decent price, and then decide ah fuck it I'll go for a new 4 1/2 digit handheld meter. So you invest some time into researching the various option, decide on a certain meter, do your last sanity checks (posting in this thread) and then ... an affordable 5 1/2 digit meter pops up. Isn't that always the way... :-DD
So I picked up an HP 3478A for $150 shipped. :-DMM Not nearly as cheap as some of those :rant: cheap offerings I sometimes see in the US, but such is life.
Chances are I will still get me a UT61E since it does look like a pretty nice meter, but the purchasing date suddenly got pushed back. :P Relative importance and allocation of limited moneys and all that.
