Remove 'buffer' from Fluke 2640, used to measure temperature.

[Kossmann]

Hi guys, i have a big, but 'simple' problem here. I am using a Fluke 2640 to acquire temperature. The problem is following:
The start of modules are slow, because it, I initialize the modules before I really initialize the data acquisition. So, when a really initialize acquisition, my Vi read all the values include, the values before i really start acquisition, how this data were in a buffer, and I dont read the real value in that time.

Sorry my wrongs in english.

Post your code or a link to the drivers used.

Follow the drivers. I cant upload the VI because it is property of my boss.

Guess your boss should be posting to this thread, too.

Can't tell you why the car is sluggish if we can't see the car.

Maybe you can upload a dumbed down version?

Follow the VIs hehe.

Wow and this program actually works?  How can you maintain this?  I can't make heads or tails of it.  Partly because I only speak English.

I guess what if you took 2 readings, then did a compare.  If the values are exactly the same one would think that the readings have been updated, and the data is from the previous reading.

What about flushing the buffer between reads.  I don't have the DLL that the drivers call but there is a chance that there is an unexposed method for clearing the buffer.

The code is rife with places where I could see potential race conditions - this may be one of them.  I can't even begin to follow this thing around.  😞

I hate to say it, but this is what happens when someone decides to "wing it" and write a bunch of LabVIEW code without really understanding how LabVIEW works.  Eventually you wrap yourself up in spaghetti and can't find a way out.  😞

But the NI rep said it was so easy and anyone can do it.  They opened an example and it did 90% of what I wanted.

In any case here are some free training links I give out to those that want to learn more.

I understand what you said, but this VI is not made by me, because it, i need to your help to understand a fix the problem, hehehe.

Sorry.
