Hi

Forgot the Hioki really nice meter and Gossen it a shame for the sensitivity on EMC and the relay, because it would give a fine meter. The Amprobe's i'm talking about are 510 and 550 ( check this specs : http://www.amprobe.com/amprobe/usen/digital-multimeters/am-500-digital-multimeter-series/amp-am-550.htm?pid=74037).

Noted about the 230V, also read some stuff. I've notice a spike  of almost 1Kv on a 230V outlet years ago on first DMM scope.  (edit )I imagine exemplifying a very small isolation, with the triac to lower the energy and measure the voltage of the AC with a spark gap between two series terminals that would connect to a load , e.g. bulb but that's not a safe example

This guy also experiments with various power line equipment.  Here he shows a cheap meter connected to one.

Looks like Voltlog put together a good overall review of the Brymen BM27s (AMPROBE PB55A) that True was posting about.  Looks like it's better than the pocketmeters I have looked at.  Lot's of slits in the board.  May be interesting to see how well it would hold up.

This is good as my old rebranded mastech that blowed in my hand while reading the mains in AC voltage...

I have two pocket meters, being the protek A800 (1994 i believe ) the first multimeter and working and the last one an offered uni-t ut120c, which is quite handy to measure low energy stuff.

https://www.eevblog.com/forum/chat/show-your-multimeter!/?action=dlattach;attach=485816

Maybe a new batch of new pocket meters should meet the joeqsmith test JIG :P including the new ANENG 302 :P

Here is the anouncement by Voltlog :

It's been a while :P And it will do a good light show :P CATIII 300V.... yeah...

Hey, you have a way to test these meters.  Now we need to get you to start reviewing them without loosing a hand in the process.   :-DD

I've been watching some of the videos of the guy with the pole pig.  He talks about getting across one of the large caps.   :palm:  Beyond making large arcs, I have not seen him doing anything with them.   

Personally, I liked some of PhotonicInduction's videos.

They just don't like much the mains voltage :P Well my memory that i had was the voltage 1536 on the display, a bang / flash. I think it will be simple by just leaving plugged into a mains socket inside a hollow explosion / fire container and let the camera take the shot., Maybe some wires to monitor the voltage. but definitly far away of  sight

Speaking of pole pigs :P .:



This is too dangerous ... ( edit) as well PhotonicInduction . put some DMM's extra and they will vaporize.

There is no way I would play around with any of these.  Even if I was far away from it when it was live.   I suspect that PhotonicInduction has some sort of background working with it.  I am not so sure about this gent. 

That last video PhotonicInduction showed with the large capacitor bank was what you want to put your meter across.  I'm sure you would get some sort of a bang from it.   I would want one of those million frames per second cameras first!

True reported four of them failed the same which makes me wonder.   Maybe they will chime in with some additional information.

Hi!
IMHO it is a sort of populism or show

No reason to destroy gear  :palm:

See hysteric tread here https://www.eevblog.com/forum/testgear/dangerous-multimeter-mastech-m890g-m890g2-(aka-dc-electronics-dc03)/

NO PROBLEM with meter but topicstarter is angry!!!  :-DD

I also use some DMM for about 18 years. Yes, it is not masterpiece - you got what you pay for. But it WORKS anyway.

Yeah that's the kind of the multimeters that are very disposable :P You pay what you get. Sometimes you get good stuff or not :P

Some pocket meters actually have more protection input than the one on the link .

Hello.  All of the testing has created a small channel.  I wouldn't say it was popular. If you are suggesting that the tests are somehow skewed based on popularity of a product, I am interested in understand why you would feel this way.  They basically all see the same transients.

No reason to destroy gear  :palm:
I have talked about the reasons why I run these tests.  It does not mean that you personally will find any value in the data.  That's not one of my goals. 

See hysteric tread here https://www.eevblog.com/forum/testgear/dangerous-multimeter-mastech-m890g-m890g2-(aka-dc-electronics-dc03)/

I also use some DMM for about 18 years. Yes, it is not masterpiece - you got what you pay for. But it WORKS anyway.
I have not had a low end meter survive nearly this long.   I have a Mastech that has various problems.  I'm on my third one now in the last 10 years or so.

They seem upset about the rating on the meter.  I personally am not too concerned about the safety ratings. I seldom work do anything that would require it.  At home for my hobby, I dare say it's never.   Which again is why you see me testing at such low energy levels.  I am more interested in a meter's ability to survive some basic low energy transients that how safe it would be with an arc flash for example.

Looks like True stopped posting.   I started to look at the Amprobe meter today and would have liked to have had them check a few things.  I hope to run it this week some time.  If anyone has any special tests they would like to have ran, let me know in the next day or so and I will see if I can include it.

Humm interesting pocket meter, EMC Meets EN61326 , Hit with the ESD gun :P

Test if it is susceptible to RF ... and also check size comparisson with previous pocket meters,

I plan to run all the normal tests including ESD, rectified line voltage and transient tests.  I may do some chemical tests as well.   

To compare size and weight of other meters I have looked at, your best bet would be to watch Dave's and Voltlogs videos.  I toss these things into the recycle bin once I am done with them.

****

I may try some low voltage tests as well as True mentions that being one of the things all the meters have in common.

I believe that in that videos where Dave selected the best pocket meter of price range didn't include the amprobe pm55 and voltlog it had an aneng, mastech and the uni-t 120c. In that case can you put the aneng like meter or fluke 101 ?

 Sorry to be persistent but it looks to me a little bigger in height than the ones that have being tested.


Well i have my offered pocket meter ut-120c and it's has less usability than i expected :( The probes don't stick inside wago's connectors so no 230V experiences :P Yes they can be placed on the test pins but metal gets exposed..

I am not sure what you are asking.  Are you wanting to know if the Fluke 101 will fit inside the case that was supplied with the PM55A? 

The dimensions are normally in the manuals which are on-line.  The PM55A is 113 x 53 x 10.2 mm.   The Fluke 101 is 130 mm x 65 mm x 27mm.   The internet is powerful.   :-DD

Yes there are manuals and specs but for example if you look at the manual of the unit 204a the picture of the meter does appear like the 203 more because of the curved lcd.

A visual comparisson always helps more. I was suggesting putting side by side the amprobe and fluke 101. 

My print is out of inks to do a real size comparrison  :-DD

001 as well.  ;D

Joe, one interesting meter that you may consider testing in the future is the nice PM300 from Sanwa; it is rated for CATIV 300V / CAT III 600V and is quite well built. It is protected by a GDT and a Varistor on a string of resistors.

Oh, the "whys" of the datasheets... The information is there not to be an axiomatic truth, but instead each speck of data must be slowly inhaled while carefully performing a deep search inside oneself to find the true metaphysical sense...
