Uni-T UT120C review and tear down
Wytnucls:
Here is a short video showing 220V RMS (310V peak) mains voltage measurement and testing of the 600V overvoltage protection on other ranges:
In case you wonder, I live on a small island and the mains voltage has a lot of fluctuations.

I've bought this little meter, although UT120B version, they didn't have the C version at the store. I'm pretty happy with it, I only use it lightly, and only problem/limitation I've found is that it can't light up most of the LEDs because voltage across test leads is only 1.5V when in diode tester mode. Otherwise, great little meter.

The 120C is available at Dealextreme for 18 USD free shipping.

Mine just arrived.
I haven't put it through its paces yet but I like the size and I like the little case it comes in. First impressions are that it's exactly what I wanted.
Edit: I just did some basic function tests. Numbers are all reasonably good - within a couple of digits on a 4000 count meter is good enough!)
Auto-ranging is a bit slow on the Ohms range (a couple of seconds to take a reading). Continuity buzzer is fast but scratchy (not latching).
Still happy so far.

Hi Wytnucls, After reading your review of this little UT120C multi-meter I purchased one of them but upon its arrival I found that some of the readings I obtained on it were a bit off, when compared with my own collection of calibration standards and so, I went and referred back to your own review, where you mentioned the four individual little calibration pots inside it, VR1 to VR4, and so I decided to 'have a little fiddle' with them, and all of that went well, for VR1 through to VR3, until, I tried using VR4 to tweak the DC mA adjustment, and I then found that no matter how much I adjusted it, it had no visible effect, at all, upon the mA current reading I was seeing on the meter..??
Now I know that this is a fairly old Post, but can you possibly, cast your mind back on it and let me know if there is some 'secret-sauce-recipe' to adjusting, VR4, that I am missing out on..??
While trying to adjust the DC mA reading, I had the UT120C, wired, in series, with my Fluke 8020B meter, and I was relying upon the Fluke's own mA reading, as being my mA reference standard, for this task.
Thanks, AOF
