| Uni-T UT120C review and tear down |
| << < (4/4) |
| 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 |
