labview & testo toolbox

[andrea11hr]

Hello If anyone of the previous colleagues remembers

I got the 80MB toolbox from testo and my dll still doesnt work.

In my case its usb, instead of serial cable, but not even the initialization vi works.

Could you give me more detail, you just ran the vi in labview and everything worked?

I still got the "class not registered" message

thanks!

It was same case for me but with Serial cable. Testo could not resolve this issue. I got new DLLs from Germany but those files did not make any difference.

So you could never measure using the Testo in Labview?

Or do you have any suggestion please?

Thanks!

I do not know about other instruments but you can not control any Testo 350 analyzer with their VIs in toolbox. We started working on writing new drivers and we requested basic commands for it from Testo. But as expected they could not help in that area as well. Very frustrating. We ended up buying different company's analyzer for which they gave all info for Labview.

You can try requesting serial or USB commands and attempt to write your own instrument driver (NI VISA functions). I am afraird it will be very time consuming and frustrating if you are not familiar with wiritng drivers. I did not attempt it.

Yes, we never got any reading from their toolbox VI's.

I have managed to get my analyzer working with labview. My advice is to get someone from testo who really knows how to program the dll's for the analyzers. I only got my project going when I finally got in contact with someone (an engineer from testo germany) who tried to do what I was doing. When he realized that the toolbox wouldn't work "out of the box" he made me some dll's to get my analyzer working!
So you must insist with testo to get your device working, because they say it will work with Labview. They have to get you someone from support to look at your problem.

Okay thank you very much for the support, at least I am in Germany so I will contact them as soon as possible.

Hello,

I got to make the program work and I got the measurements using Labview.!!! It works without problem and without receiving any help from testo.

My suggestion is to try it out in another computer. I was working in 64 bit computer and I do not know much about computer architecture, but I got to make it work in an Windows XP 32 bit, maybe I´m wrong but I was tired of going around reading "registers" and about DLL.

In my case I changed to InitSerial, added my device to the "select device" cases as 435-635-735

My new task is to make it work in the modern computer. Any ideas are more than welcome 🙂
