MultiMeter

On an Email group I monitor one member was looking for a DC voltmeter with a USB interface and compatible with Linux. Hence does the UT71e have a true USB interface? Does the software work with Linux? If it is convenient please post your comments abut the UT71e's PC interface and the software,

I notice there are a lot of voltmeters with a USB interface but they only come with Windows software. The only possible exception I found was the UT61e. However, the information in the data sheets was so skimpy one couldn't be sure what he was buying. Hence it would be cool to get comments from a person who owns a similar instrument.

It does not specify A/C voltage ranges. Also, what on earth is "Input Impedance for DC Voltage Measurement DC 200mV : Around 2.5GW All Other Ranges : 10MW" supposed to mean? W means ohms?

I'd guess, yes. There are systems where [meta]+[roman character] is used to indicate the corresponding Greek symbol. Mathcad, for one, although it reverses the order to W + Ctrl-G to get a capital omega.

That's a heck of a lot of functionality for the money. A comparable fluke is 4x the cost.

And of course now that I am aware of it, I've seen it a couple of other places - mainly the Frys website.

Yep - I'm very happy. I used to have a Fluke 12 until I needed to measure some current - since then I've been using a variety of no name meters. This one is excellent!

It sets up as a USB com port / serial port thing - no sleep I can't remember the right term for it. The software is only Windows but considering how it sets up a cleaver guy with too much times on his hands could do a similar program in C++ for Linux.

It sets up as a CDC device.

BTW:

Microchip USB to serial converter $1.42 in 1000's looks similar in capability to FTDI

Yes it does, but you have to scroll way down to find it. AC Voltage 4V/40V/400V/1000V

IOW, C++ programmers are ax murderers?

Couldn't agree more ;-)

I especially like that ten mega-watt input impedance on most DC ranges; good enough to fry anything.. The 2.5 GigaWatt range is overkill..

Yes; unfortunately, it is WELL KNOWN that the Greek Omega symbol gets "converted" to "W" and the stupid spec writers refuse to use either the spelling "ohms" or an artwork nonfont glyph that cannot be "converted". This is so common that it is a miracle that this stupidity has not started a war..

I'm sure he meant THIS:

Mind you, that predates LCD readouts by a little bit.

TYPO! TYPO! ... I'm sure a clever guy ...

Where did you find plug adapters for use with the power adapter and power strip that comes with the UT71?
