if i was testing frequency, i would be using logic to generate it.

Fair comment, but in the video - at 15:50 - he says "RF generator"  :-+

I've got the Peak Meter branded version of that (the PM18C) and it's a pretty nice meter that works well. But I doubt it would appeal at all to the AN8002/8008 audience; it's about four times the size and manual ranging.

have you opened it? i mean have you confirmed it's DM1106EN based and not DTM0660? ADM08A is using DM1106EN for sure. [EDIT] I found review in Russian here:

https://mysku.ru/blog/taobao/49127.html

and it's DM1106EN - also they list price of 13 USD [EDIT]

from my understanding for what main purposes people here want to use AN8008, i don't see manual ranging as an issue.

Personally, I wouldn't mind manual ranging, but then - I haven't had an auto ranging meter yet. Functionality wise, for a 6000 count, it is more expensive than you can get the AN8002 (which is about $13-14 lowest price). None of them have a huge price difference though.

IMHO, that's unfair comparison, because at least ADM08A, (which outside design is the same as Peak Meter PM18C, but I don't know if they are the same inside) is using the same chipset as AN8008 (DM1106EN) and it cost less than 19 USD delivered.

counts for those chipsets are just setting in the EEPROM, you can set those meters to any count up to 9999 with changing 2 bytes in their EEPROM, but DTM0660-based meter like AN8002 cannot go more than 8500 counts. so, what I am wondering and interested to see, someone who has the necessary equipment to make tests - hack the EEPROM of DM1106EN-based ADM08A to 9999 counts and compare it against AN8008. in fact AN8008 EEPROM dump I posted above can be used as reference for such hack.

price-wise AN8002 is the cheapest, then it's ADM08A and then AN8008, but both ADM08A and AN8008 has same new DM1106EN chipset and ADM08A has better overall build quality and if EEPROM hack to 9999 counts is reliable then ADM08A is better choice.

stj:
if DM1106EN is a replacement for the 0660 then it could even be in some 8002's like it seems to be in newer UT-210e's

More useful than a square wave output!  :)

(Now I need one of those as well.  :scared: )


PS: Do you think I should send one to Batteroo for their test lab?

That is the cheapest meter I see with battery tester ($3.7).

That one and the free-with-coupon-but-still-really-cheap Harbor Freight/Cen-Tech meter.

I've opened it, but I didn't check the chip. (I think it may have been under a blob of epoxy.) The interior, BTW, looks ok, especially for a cheap meter; it's got much larger fuses than the AN8002. I worry about the circuitry that brings inputs up to the transistor test socket at the top, though; I don't know much about this but that doesn't seem like such a good idea to me from a safety point of view.

No, but the selection of ranges might be. My PM-18C has different holes in the amps ranges; instead of 100?A/1000?A/1000mA/10A (.01/.1/1000/100k ?A resolution) it's got 60?A/60mA/600mA/20A (i.e. .01/10/100/1000k ?A resolution). So it drops a bit off the bottom to give a bit more in the middle, as far as the low current stuff goes, and high current is less precision. That sounds better to my mind for general purpose stuff (again, I'm a noob), but maybe the .01 ?A resolution is useful for some stuff. (I would think when you get down that low you'd probably want to be measuring voltage across a known resistance already in the circuit, wouldn't you, in which case the meters are the same because same lowest voltage resolution?)
