content: the UNI-TUT61D$43.19 from ebay is worthy ?these ebay uni-t models are real or fakes?

content: I've a Sanwa CD770 and here are my comments on it..I like this Japan built quality DMM but there are a few things missing ( the higher model have it at a much higher price ) :-- Current measurement, only 400mA, no 10A- no backlightOverall, I am satisfied with this model, pretty fast readings and good accuracy ...

content: Quote from: neutrino on December 31, 2010, 02:24:29 amI haven't seen fake Uni-T meters. Fraudsters, when going through the trouble to fake a meter, like to target the high-end brands, because the margins for the fraudsters are higher. Uni-T is low-end stuff. It is not the bottom of the barrel, but it is nothing to write home about. They aren't high-end meters in stealth mode. You get your $43.19 worth, but not more.

content: Quote from: stan001 on January 01, 2011, 05:58:01 amfor me, this is to be taken seriously, i will trash any dmm model from my recommendation list if it cannot do 10A (unless it has very special feature that other dmm cannot do). i recommend Unit-T... reason? i own uni-t71a, how good it is? i'm not sure, but i believe it serves my purpose, i just will not expect it to be higher or the same as more expensive unit. i got what i pay. and Dave reviewed Uni-T without any serious comment/issue.

content: yea really unless you know you will confine yourself to low power stuff you need a meter capable of 10A as a first meter, after that look at meters that are more niche but good at what they do

content: Quote from: Simon on January 01, 2011, 06:19:49 pmThe second would be 25A ? And the third 70A ?The first one could be what ever you can find, experiments with small batteries does not needthat power in Ampere .UNI-T will be fine as option.

content: Quote from: Kiriakos-GR on January 02, 2011, 04:30:29 amWell I'm sure one of the first things a hobbiest may do is use a car battery as a power source and want to measure charge and discharge of it. I say the first meter should be general purpose with a 10A range, after that you could get a more niche meter with only 400mA but hopefully that would be a better quality meter or have other nice functions
