Which new Multimeter i should buy
<< < (6/8) > >>
Irukandji:
Can the Aneng An 8001 - 8009 or the renamed models measure 10mA or 20mA? I dont know if i understand it right on the eevblog video to the aneng 8008 but it saw like he cant measure it. But the aneng 8001-8008 is not safe to measure 230V if i only put the probe in the 230V socket?

The Uni-T UT139C looks save when i understand it right on the video from joe smith.

AN8008/AN8009 DMMs can use 1A range to measure this currents. It is not the best way to go, but it is acceptable for small meters. The problems are 0.1 mA resolution and 1% +3 digits accuracy (for 10mA it is +/-0.4mA).

UT139C is larger, has better build quality, more functions (REL, MIN/MAX, NCV, ...) and current ranges. It can make 10mA and 20mA measurements using 60mA range, with 0.01mA resolution and better accuracy (0.7% +2 digits, for 10mA it is +/-0.09mA).

I would not recomend you to use any pocket meter for this job.

I think i buy now two multimeter's. One is the Uni-t UT 139C and the other one is one of the aneng 8002,8008 or 8009 or renamed model. These 3 models and the renamed models are same accurate or?
If i buy the Uni-t UT 139C about Amzone how i can know if it a europe version? I read there is a china version of the ut 139c on the market is it true and what is different?

best regards :)

If you want the CAT ratings to be real, look for the icon of an independent testing agency like UL or ETL (and whatever the German equivalent is) somewhere on the meter.  CE doesn't count because that is usually a self-certification.

The Aneng 8008 is NOT UL Listed, the Brymen BM235 is.  One can assume that the 235 actually meets the CAT ratings.  No such assumption can be made for the 8008.  For my purposes, the CAT ratings are not important.

The EEVblog 121GW meter is not UL Listed but it is listed by ETL - an independent testing agency approved in the US.  So, it's listed...

I think the Uni-T 139C is a good choice for you. With it you have the ability to easily access the small fuse. When you buy a meter, also buy a set of fuses in the right size. You may need them one day. ;)

In case of the Uni-T 139C that is: 6x32 mm  FF 600mA H 600V (according to manual).


EDIT:  About safety and mains, here is how I see it:
Every Phasenprüfer for 1 Euro is more "unsafe" than your multimeter. When people say, "the meter is not save on mains", this does not mean that it will automatically turn into dust when you measure mains with. I read the linked article above: it basically says, that you need to be careful and that a good quality meter doesn't protect you from main, but it helps to protect you a little bit from your own stupidity. I ALWAYS treat mains with respect. I plan every hand move very slowly and don't take any risk, when I work with it. And you should too – but most of all: don't be afraid, or you shouldn't do it at all. Don't be too concerned about CAT ratings, they don't protect you from your own stupidity. Such a meter is ok, when you occasianally want to work with mains. Should some day come and you find yourself working on mains routinely on a daily basis: then by all means get a very good meter, that is suitable for this kind of job! But for now, I only can say: I measured 15A 240V with my 25 Euro Multimeter VC97; I'm still alive and so is the meter. ;)
