In one of my orders from DealExtreme, I had put a UNI-T UT10A in my cart for review. Well when I pushed the buy button I forgot to remove the meter. I decided to get it anyway and see how bad a $12 pocket meter could be.
http://www.uni-trend.com/UT10A.htmlAs far as pocket meters go, it didn't feel half bad so I decided to test it and see how good it was.
It feels solid in the hand with no cheap feel to it. The LCD window cover is quite flexible but it takes quite a bit of pressure to get any distortion on the LCD. The display is easy to read and updates very quickly, probably 4 times a second.The selection switch feels a little indecisive but it is not a problem in practice. The leads are permanently connected and have good sharp probes. The selection buttons for the alternative functions feel a little soft, but nothing to complain about really.
To change the battery, it is necessary to open the case to get at the CR2032 cell inside. Fortunately and surprisingly for such a cheap meter the screw has a brass insert so it should not wear out too quickly. Inside the construction is quite tidy and the quality of the soldering is very good. This is no ruggedized meter but it certainly is not a fragile one either. The only input protection in this is one PTC. I am not worried as I don't think I will be testing 480V mains with it.
The functions that this meter has makes it quite useful for general electronic testing and low voltage bench work. It matches or exceeds its specifications in any test that I can verify, some of which can be seen in the photos below. Mine was accurate beyond its specifications but this is only a sample of one. Out of my three UNI-T meters, the two least expensive ended up being the most accurate out of the box. The continuity test is non-latched but is instantaneous.
My conclusion? This is a useful meter and a good buy for the price. It is lacking any kind of current measurement but that isn't what a pocket meter is for. If you want to do current measurements and test high energy circuits then you should be looking elsewhere. If you are looking for an inexpensive and useful pocket meter, then consider this one for good value.
