What "example" are you opening? Did you install the LabVIEW drivers for the device?

this is the link to the drivers i found https://decibel.ni.com/content/docs/DOC-4785

this is the text from thatpage:

PicoTech Picologger TC-08 Thermocouple USB interface

VERSION 1

Functional Description

These VI's provide a more uniform route to communicating with the TC-08.  They also allow modification of parameters such as temperature readback.

Caveats and Additional Notes

The USB device must be detected by the OS and the DLL (included) to be placed in the system32 directory.  If the unit is already in use by another program then the VI's will not work, likewise if the device is not closed it cannot be opened for additional reads.

That's not a driver from NI so it's unsupported. I would be suspect of the provided dll. My guess it's not the same as the one from Pico. The Pico website says it has example LabVIEW code for use with their api. Have you tried that?

Hi marc92040,

I dug into that community example a bit, and it looks like they are just making a DLL call in the OpenTC08 VI. Maybe you can comment on the community example and/or try to contact the poster of it, as I don't know why the DLL is not correctly opening the port requested. Also, it strikes me as odd that the DLL function does not require any input, such as a port identifier.

Have a nice day,

Andrew
