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%.
Most of these meters are from reputable companies. Some of them come standard with calibration certificates or as an extra option.
You can generally work on price. The few meters from less well known companies, selling for less than 150$, are the most likely to drift over long periods, as they tend to use cheaper components.
Among those, I can only vouch for the UT71 series, two of which I test regularly. My 61E, unfortunately, didn't fare so well.
Most companies still recommend an annual calibration for their meters.

New file: A few more Fluke meters added to the list.

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.


and to the fact that accuracy is not guaranteed outside of 18-28C

Wytnucls, this is a great list!
One remark: the Fluke 179 measures frequencies up to 100kHz in both the VAC and VDC, therefore I have the impression its bandwidth is not 1kHz (despite the manual says the bargraph can't be trusted above 1kHz). Maybe I am wrong?

Also, not much love for the BM857A... Possibly due to price/features?

And what about the DT-830?  :o

I'll do the CEM meters shortly.
Bandwidth is quoted for TRMS accuracy, usually until 1 dB of attenuation. It has nothing to do with the frequency counter.
For instance:




New file being loaded with older Fluke and Yokogawa meters.

Nice list, 2 things can be added:

* (configurable) auto off
* dial knob with only off-volt-ohm-amp or with 20+positions (there is some correlation with autorange)

Well one thing that you don't have is manufacturer specified battery running time - as this is handheld list some of the models have really awful running times that I weigh in when comparing models.

Great!!!

I started a little Fluke file.

Here's what I got so far using your spreadsheet. double check my entries. The accuracy, I am not sure how you entered that.

Fluke 115 does not have LowZ mode and it does not have proper jack detection. It only displays "Lead" warningn when you turn the switch to current measurement.

Good catch on LowZ. At least it gives you visual warning on the current leads. Maybe a separate column for that?

It has a LoZ feature for capacitance measurement. The feature may not work for ghost voltage detection though. Fluke still calls it LoZ mode.

Lead warning is just that, but it is an attempt at better safety on the current jacks.

I limit the file to meters with a resolution of at least 6000.

Just about all meters in the list have an auto-off feature, except for the 61E. Configurable is nice, but not a major deal breaker.
I have to limit the number of columns to the most relevant information for readability. It is not meant to list all the meter features.

I thought when people talking about DMM's LoZ input "mostly" is for voltage measurement ?

Putting it at LoZ column probably may misleads readers, maybe another extra column for "LoZ Cap" ?

This is a really impressive undertaking Wyt. I will find this extensively useful.

I can't add too many columns. I will add a note to mark the difference.

New list with the true RMS V&A multimeters.
http://www.mastech.com.cn/
The Shanghai company seems to have split up from Mastech.
They make a lot of advanced meters, but the quality of assembly was rather shaky in the past. Hopefully things have improved now. To be confirmed.

Great work! One tiny error I've noticed - Brymen BM867 does have 4-20mA measurement.

Great works !

A small precision : Metrahit 28S (and some others I think) can be connected to PT100, PT1000, K and J thermocouples.

Yes, 28S and 29S can handle K and J type probes.
18S, 25S and 26S Pt100/1000 only
The listed current Gossen meters can do Pt100/1000 and K type.
Only the 30M has the 4 wire temperature measurement capability.
Will update the file shortly.
