Strain measurements using labview and DL750 scopecorder

[Tickle]

Hi

I want to use labview to do strain measurements using DL750 Yokogawa Scopecorder. I have installed the DL750 drivers and I  can access them from labview, but I am a bit lost as to getting to communicate with the scopecorder, setting up measurements and so on. I am all new to strain measurements and to labview, is there a link or a tutorial that anyone would recommend I refer to?

Regards, tickle

Hi Tickle

It looks like the driver you are using is supported by a third party. I took a look at the driver you are using and it has a couple of examples included with it. I would recommend taking a look at these examples as they are normally a good starting point for communicating with your device. Has anyone else used this device in LabVIEW?

Hi Adam G,

Thank you for your reply. I tried to run the examples but I am getting a number of error messages. For instance if I try to run application example 2, I get the following error code...

Error -1073807346 occurred at VISA Write in YKDL750 Wait Update.vi->YKDL750 Application Example2.vi

Possible reason(s):

VISA:  (Hex 0xBFFF000E) The given session or object reference is invalid.

I am not sure how to proceed...

Thanks in advance,

Tickle

Hello,

It sounds like the reference to your VISA session is getting lost somewhere in the example. You can try using highlight execution and probes to determine where this reference is getting lost at. You would want to put probes at the VISA reference wires to see where it changes. Have a great day!
