The above spot on.
Test it in notepad. push button and should type. Then you know the link working.
In excel be aware that it is just a keyboard typing so be on the correct cell before pushing the button on the caliper.
Wrong spot and it will overwrite any formulas or whatever unless you have protected those cells.
It is just like you typing at a keyboard in most cases,
Some have the ability to query from the excel computer side with no touching the button on the caliper but that gets harder to do in excel and you will have to know VBA how to make this call.
This done if you want a real time display on the computer like say a DRO type deal.
Who'd of thought that you could make a DRO in excel?
Then one can do 3 and 10 points circles and arcs, angles, orients, extra coordinate systems, tool offsets.... oh my.
