It's probably beyond the scope of this spreadsheet, but it would be nice in the PC column to differentiate DMM's with free software for logging vs those which will cost you another $200 (Fluke). If this is a feature you need, this can unexpectedly add a great deal to your total price.
Perhaps just a note in the PC column at the top of each manufacturer such as "Software is an additional $...".
Thanks!

It is there already, under 'Kit', next to the PC column, with a tick in green for free software and USB/RS232/BT DMM connection.
What I could do is insert the price of the software and cable in the 'Kit' column, when it has to be purchased separately.

Column headings are explained in the notes found on the first heading row.
In this case: Bar graph, Max/Min, 4-20 mA current loop and non-contact high voltage detection.

FWIW there seem to be a bunch of errors in the Fluke 87V specs that are shown in the spreadsheet and spreadsheet image (e.g. 6k rather than the actual 20counts etc, V DC resolution, uA DC resolution). Probably because the Fluke website lists a number of these incorrectly (I'm going by the values reported in the manual)

The Fluke 87V is a 6000 count multimeter, with a high res mode of 20,000 count.
The published accuracy figures are based on the core 6,000 mode, as they don't improve in high resolution mode. (Fluke manual May 2004).
Resolution does improve in the 20,000 count mode, but I'm not sure to what extent, as I don't own the meter.
What I will do, is list the published figures for the 6,000 mode, to avoid any confusion:
mVDC resolution 100uV Accuracy 0.05%+1 (0.1%+1 on mV range)
uA resolution 100uA
Thanks for your input.

The high res mode is noted in the spreadsheet already. Just hover with the mouse over the count cell.

I have compiled a list of the most popular bench multimeters. The meters should have a count of at least 5 1/2 and be able to measure currents. The most important DMM features are listed. Shout if you spot any mistakes or if you think additional features should be mentioned.
Codes: RJ (Rear Jacks) Pk (Peak) Cn (continuity) Clk (Clock) ExT (External trigger) D (Delay) S (Samples) Mc ( Measurement complete) Tr (Trend plot) Ma (Math) P/F (pass/Fail)

Nice work. Since you added the flukes Any plan on adding other older models such as the Agilent 3468, Keithley 196 or 199, etc.
Also, maybe dBm measurement column? Some people care, some don't. Still a GREAT reference.

Love the new bench section - great work. Looks like you're missing the 3458a (not exactly a common piece of equipment if course)

Updated version of the bench meter list.
Most of the math functions are listed now.
Math functions:Z Zero/Null
B dB, dBm
X mX+b
O Offset
R Ratio/Relative
Statistics:M Min/Max
A Average
D Standard Deviation

Very well done. Might want to include a channels option or something. The Keithley 199 is technically an 8 channel meter.

Very nice work!
A small corrrection; the Brymen 82X -series all have dual display (most, but not all modes are dual display on my 827).

Correct, I will modify the Brymen entries on the next update. Thanks for the input.

What a great spreadsheet!, thanks!
Just a couple of comments regarding the HP3478A bemch meter:
1. It has HP-IB (GPIB)
2. Regarding the accuracy - it seems you are quoting the"old" specs, the accuracy specs were improved (for any meter with a serial number greater than 2520A22585) you can see the new specs in the "new" brochure here: http://www.ko4bb.com/Manuals/HP_Agilent/HP_3478A_Multimeter/HP_3478A_3468A_B.pdf and the "new" operators manual : http://www.ko4bb.com/Manuals/HP_Agilent/HP_3478A_Multimeter/HP_3478A_SM_Rev2.pdf
The best accuracy, for this revision, is 0.006% of reading + 2 digits (for the 3V range)
I do not know how to show this in the spreadsheet, perhaps you can add a comment on the specs cell?
Thanks again!
Ran
Quite right, HP-IB is indeed GPIB. I will also add a note to quote your comments on accuracy of later meters.

Might do that later. It seems that most of those channel scanners were optional though, and thus possibly quite rare. Thanks for the info.

That is quite possible. Both of the meters I have came with the scanner card. They were purchased as is stock from a company. So I'm not sure how rare or not they are.

it's very sexy now.
you've got the 3478 and the 3468, but why not 3457 or 3456, they're fairly common as well.

I thought the half-rack size meters were more versatile, but I'll list those two anyway, as there is still a demand for them.
The 3456 looks mean, but doesn't measure currents.

Hi Everyone, I bought a PCE-PDM 1 Multimeter for a few weeks and found it was a good instrument, all the offers they have there are pretty good, just thought I´d say because I never found it in the spreadshhet?

4000 count pen type, not TRMS, made by CEM in China (DT-3219).

Didn't notice input impedance in the spreadsheet. Probably not necessary since all mm are 10Mohms? Just guessing.
