So what's the verdict ? I need a 2nd DMM for breadboard level stuff and for upto 240V mains heaters/hotwater boilers, once in a blue moon. And I don't want to take my quality DMM out of my house.

So for $50 is a good choice for that ?

If it really is "once in a blue moon" then you'll live. Just make triple-sure:
a) The leads are in the correct holes,
and
b) The dial is on the voltage range.

(a) Is maybe the most important. You can get it right by measuring a 9V battery before you start.

the verdict to me ,  buy an good brand meter, good input protection, good behavior   etc etc ...  for a little more $$ you have some well built mastech models, and the fuses and batteries are easily removables  the 8240 or 8340 ??? 22000 count dmm, but i think they have changed the revision model, and removed a fuse, mine was an 8240d if i recall corectly and had 2 hrc fuses ??? and data logging features too

theres a thread for some mastech meters and pictures of them

Is the speed of AN870 / RM219 measurements anywhere close to UNI-T UT61E? Or how much does it differ from the previous models? I am looking at RM303 / ZT303 that should be similar in performance.

is there an ANENG equivalent for this model?

I've been watching videos of people making modifications to their UPS's and came across this video.    ANENG in a zip lock bag.   I wonder what their concern is.

The ANENG meter was probably a sizeable investment to the person in the video and they wanted to protect it in case of a lithium battery incident.  Not unlike the patented Joe Smith meter coffin to protect everything but the meter when destructive testing is happening (only in reverse).

There's a TMI meter in a ziploc bag also @57:25. I think that plastic bag purpose is to protect the meter from environment not to protect her from the meter.

If I read the specs correctly 60mA range is also missing like Q1.

Just get the ANENG 860B+, it's the one to get!  :popcorn:

You could very well be right but if the packs come apart, how much protection does a zip lock bag really offer?   Maybe when they spot weld they get some splatter and the bag is enough to stop it.

I don't have an 860B+ but I still think you might be right. Neither of the 2 870 I bought held up to 120v mains and basic accuracy testing. That's pretty bad despite accuracy being pretty good. The Q1 has a neat screen but that's about it for that one. I bet that relay dies WAY before you'd expect too.

I was set on ordering ZT302 but few here recommended ZT301 over ZT302. The latter is missing 10mA and 100mA but the former is missing 1mV range that 8008/8009 have right? So no 1uV resolution?  How useful is it to have 1mV range that has 3 decimal points?

Now I think I might hold on for ZT303/AN303/RM303 to go on sale.
