I've just discovered Metraport 32S
Which I found as very useful universal Multimeter
The 40s is the current model.
I think it would fit in the excel list as a further Metrawatt Item.
Thanks for this Wytnucls. It should help people who have no idea what is available.

The 32s is very unusual. Input protection is rather strange. A 380VAC fuse on the mA range and a resettable circuit breaker 240VAC/50VDC, combined with a 500VAC fusible link. The AC bandwidth is not great at 1kHz only.
The form factor may suit some people though.
Uh, the BM869 is only 251$ for the meter and ~60$ for the IR connection cable. (tme.eu) (USD cost)
and not everyone really needs the IR cable or computer logging.
you should probably add a little tab for cat 2/3/4 ratings, and possibly scratch off the ratings for meters whose internal construction does not satisfy those ratings.
I really love your idea though.

In Europe, you have to add VAT to the TME prices, which is quite substantial. As I said, those prices will vary from one region to the other. You will have to do your own research to find the best deal, delivered to your house.
CAT ratings are not that important for electronic work. Most of those meters are rated CAT III 1000V/CAT IV 600V anyway. I try to limit tab numbers for better readability. Fuse voltage rating is quoted, which is a good indication of general safety.

I think it's the same outside of the EU. and I don't believe for outsiders(of EU) that there is a cheaper place to buy from. even Franky got price-stomped on by tme.
The latest spreadsheet, with non true RMS meters removed, and some Gossen meters added.
I have cleaned up the layout, with green highlights for best features and amber, for below average ones.
(The spreadsheet is updated in the first post)
This along with the bench counterpart would make a great Multimeter Comparison page, say on wikipedia (as we have nowhere else the community can colorabate + edit).
The BM869 has %4-20mA, maybe you can change temp. to '2'
Maybe also add the BM867
Maybe also add a column to indicate optional connection to PC
Also if possible add a hyperlink in the excel file to the specsheet if available

Thanks, correction will appear soon, BM867 will be included. PC connection is under IR.
Will see about spec sheet.
What about including some actual measurements and tests from meters? We should have good data about some of the meters from this forum alone. I know it might be a lot of work, but cheaper meters like Uni-t always have their quirks. Like ut61e has high burden voltage because of the relatively high value resistors in current range, where as ut61d as example has low burden voltage. From what I've understood from EEVblog and TheAmpHour Fluke meters always exceed their specs, because all the drift of all the components has been included in the error calculations of the specs.
Specs quoted from manufacturers don't always tell the whole truth, for example ut61e can also measure hertz far higher than what they actually tell in spec.
I can see why you might want independent specs or performance included in this but these are variable and have nothing to do with what is promised by the manufacturer. One person's experience is not guaranteed in anyway and could mislead someone to buy something based on mistaken results or fanboyism. Maybe a simple index of whether the meters generally meet their spec and build quality would be in order but it would be a horrendously huge task to compile such a meta opinion.
The latest spreadsheet was updated with a few meters added and also with hyperlinks to each manufacturer's internet site.
If I may, only two small points to be corrected IMHO:
1. Fluke 87V does not have LowZ mode
2. Both Fluke 287/289 have InputAlert jack warning

I like it very much, because it has an unique hold feature, it allows to connect the test object, wait for acoustical feedback. The measure is frozen until I drop it.
And the continuity test is incredible fast; about 50ms!

Thanks Nermash, corrected.
Most of the Gossen meters have that auto hold feature. If the next measurement is very close to the first one (less than 100 digits on the 26S), you get two beeps . If the new measurement is different, only one beep.
The first measurement is used as the reference throughout.
The 32s is only rated CAT II 300V, which is fine for automotive or electronic work.

As this is my first Gossen after 10th of years this was new to me.
I like it!
My first was one of the first 3-1/2 DMM ever. Nothing more than displaying the Measurement :-)
Uni-T UT71 is rated at 5A continuous
Great work , thanks !
Although there are many others more, I think these extra specifications are interesting aspect as well, suggesting to add 2 more columns for "Operating" Temperature and Altitude if applicable or stated by the manufacturer.
These are for Fluke :
87 V, 287 and 289 :
Operating Temperature : -20 °C to 55 °C
Operating altitude :
87 V : 2000 m
287 & 289 : 3000 m
Again, just a suggestion.

Oops, quite right, forgot about that. The 61E too.
Corrected.
Also added Fluke 187 and 189 to the list.

Interesting aspects, but they will only affect a minority of users, so best left out I think, but thanks anyway.
Maybe a simple index of whether the meters generally meet their spec...
I think this would be great, if say, you don't recognize a Fluke from a whatever... Some indication of general "trustworthiness" would be helpful since I only recognize one to two brands.
I just spent some time doing my home style "calibration". I bought a DMM check and in short, my 30 year old Fluke 8050A's spec'd to be about 0.1% accurate, look to be more like 0.01% accurate after 30 years. Some cheap UEI meters are much newer, and at the edge or just outside their specs of 1%.
Some indication of general "trustworthiness" would be helpful since I only recognize one to two brands.
If it's new, the meter normally will be delivered together with a calibration certificate.
