I'm using the wireless tool setter on my Haas, and when I measure a tool it gives me the positive offset measurement.

I want to use a negative offset.

I am using the face of my mills table as my baseline for measuring tools, so that's why I want to use a negative offset.

So with that in mind I want to take any measurement that my tool setter comes up with and minus 20.9186" ( this will give me the same measurement as I would get if I used a dial and measured off the face of the table )

What would be the easiest way to have this automatically calculated whenever I use the wireless tool setter to measure a tool?

Thanks,

Kent
