SURPEER AV4 True RMS 4.5 Digit Multimeter

[EEVblog]

Interesting meter.
4.5 digit, 0.05% class, CAT IV 600V rated supposedly (not certified), and only US$37 (in special)

VoltAlert™ is Fluke Trademark of non-contact voltage tester (NCV)

not accustomed to flukes, so i though it was something written in chinglish

It might as well be chinglish.  It is more than enough for the Fluke Customs Man to have a go at seizing them, as they are know to do...

This is a VoltAlert, they come with batteries.  The batteries insure built in obsolescence, when they leak you need to buy another one.

I couldn't see any accuracy specs.

Even the manufacturer's page does not seem to think it is relevant:

Cat IV 600V supposedly.

Company slogan:

"Life's in good hands." What does that mean?

[sleemanj]

I wonder if that rendering is accurate... *two* large chips on board, plus an eeprom.

It is.

The "CAT IV" clearances look like the meter was designed by a company that makes meat thermometers and food grinders.

250V only fuses.

The design is similar to the HYELEC MS8236/PeakMeter PM8236, two chips solution (DTA0660 (6000 counts) + Hycon HY11P14) + eeprom

Maybe this one is HY3131 (50,000 counts DMM Analog Front End) + HY11P14

not many DMM chipset has NCV function. Hycon chipset is one of them has NCV

Possibly the OEM manufacturer:

Sampling rate: about 3 times per second

I bought one of these and have just checked it out. Posted a long review with photos on Amazon's site where I bought it. For $37, it's a fairly nice meter that tracked an HP 34401A meter fairly well. I wouldn't use it on ac mains or other high-voltage circuits but I've no problem using it for the stuff I usually do.

How's it going? It looks like a very interesting meter if it meets all the specs.

It looks very similar to the Zeast 282 that I have looked at: http://lygte-info.dk/review/DMMZeast282%20UK.html

Code: [Select]

The meter is easily within the specified tolerances and in many cases only one or two count out.
0.05% meter for $<$40 

Code: [Select]

Display updates around 3 times/sec
Bargraph works at same speed as the numeric readings.
Slow bargraph 

(better than no bargraph at all?)

Code: [Select]

0.05% meter for $<$40 

Yes and no, the +/-count is a significant part of the tolerance on voltage.

Still far more accurate than the 0.5% meters typical of meters in this price range.

Also: Proper fuses, NCV, temperature probe, etc. It seems like a good deal overall.

Is it a good meter in use? (ie. Did you end up using it...)

I do not use all my DMM's, I have way to many, especially after I started doing reviews of them (I have many more DMM reviews on the way).
And for most of my work I use bench meters.

[Hydrawerk]

Looks like a decent meter in its price range.
Input protection looks like total fucked crap, but in 1993 we were happy with Metex M-3900 that had no input protection.

I think we can admit to ourselves that some meters are suitable for mains work and some aren't, then use them accordingly.

I have quite a few but the one I use the most lately is one of the cheapest - an AN860B+. Go figure. 

I think the meter in this thread looks good in white. I might get one if/when my AN860B+ dies, it looks like it has similar heft.

Just bought one, the Surpeer Amazon store is clearing stock at £23.99 inc' delivery fulfilled by Amazon. Seems better spec'd than the ZT219 I was looking at, 9v battery is a minus though.
Old thread I know.

I just picked up a Thsinde 18B+ for $12.95.  I no longer see the deal.  It's 6,000 count. Decent for the price!!! little slow on continuity but I love it. 

I was researching and found a Surpeer AV4 is $20.99 on prime now.  Not sure why a 20,000 count would only go to 20 Meg Ohm. It seems like trickery with 20,000 digits but really only 2,000 count.  The advertised tolerances should be tighter as 20K...

On the flip side the Thsinde has similar circuit board and HRC fuses... I think they are from the same factory as Surpeer and perhaps the HY stuff.  I'm loving these cheap meters.  I have a Fluke and AW Sperry.

Currently $13.99... It seems a good deal.
