UNI-T UT61E Multimeter teardown photos.
PedroDaGr8:
Close, the "new" scope is the apparently quieter LeCroy 9410 with all options (including FFT). This one isn't that loud at all, more of a gentle purr. I picked it up locally for $120 with two tek 10x probes thrown in for free.

Noticed on the website the UT61E is supposed to have a backlight http://www.uni-trend.com/UT61E.html , although the manual indicates otherwise. anyone know what is correct ? Looking at the first post it appears there is no backlight, but things can change..
thx

Lightages:
The UT61E does not have a back light.
mariush:
It also says sleep mode 15 minutes while there's no such mode.
No, imho, it's just bad data. The english version of the site is not really updated, check the chinese version always:

(^^Google Translate above) No backlight and sleep here.

I am reasonably happy with the 61E. I already have 3 others - 2 radioshack and a DT830B. But I actually was thinking about getting a couple more DT830B's when I was playing around with boost circuits:
In Volt, in current, out Volt, out current, drain current, that is 4 right there. I could use another one to do adhoc readings.
One of my 4 is a DT830B, $6 DMM, not bad. I use it as my volt meter for my PSU. It actually performs better than the other cheapos from Radio Shack (4-8 years old). So I was considering getting a pair of DT830B. But I hate all those stuff on my table leaving me so little space.
I would not invest in another mid-low end DMMs. If I would get more DMMs, I will probably aim for a higher end ones or real cheapies. Mean time, I just got my ATMega328 as Volt/Current meter working on a breadboard and ordered parts to transfer it to PCB. I divided up the 6 ADC's as 3 pairs of volt+current (switch-selectable) 0 - 5/15/30Volt and fixed 0-4Amp (using a 0.1ohm as current sense and amplified with OpAmp). The two pairs I have working gets me +-1% to 4% accuracy. Not bad when I have not yet calibrated them yet. After I get the parts, I can get the 3rd pair working, transfer it to PCB, and then I'll do some software tricks (the ADC under-reads at low ranges). If I can bring it closer to 1-2% using my UT61E as "accurate" reference, I just may end up using the ATMega as my PSU's volt+current. All three channels shares common ground, so it took me a while to figure out how I would make that work for me. If the thing works (at +- 1-2%), I don't need the DT830B's as volt/current meter. If it doesn't, well, I learned a lot trying to get it working so far.

Please keep us posted on how your Atmega328 meter reading project is going - I'm sure some folks would be up for trying your design if you want to share it. Thx
