Hello zhubajel,
I apologize, I may not fully understand your question. I will try my best to describe the purpose of the cal files.
The cal files contain the correction information needed for the device to make accurate measurements. The cal files are generated and are different for each device.
Any time you use the API to control the device, the files are stored and read from the ProgramData/ folder. The ProgramData folder is the place Windows expect us to use to store this kind of information.
I have recently emailed you about an issue on a different forum thread, if you would like me to send you the cal file we have for your unit we can so you can verify it is the same as the one pulled from your device. Let me know if you want this in your email reply.
Regards,
A.J.
