Touch triggering a probe with a SP25M Probe

I have a Browne and Sharpe "ONE" Machine with a TP20 Module on it,
I just recently purchased a used B&S "Global" with a SP25 body w/SM25-1 Scanning module on it.
I'm going to purchase a TM25-20 (SP25 to TP20 adapter)
In the mean time does anybody know If there is a way to force my scanning head to touch trigger probe the Calibration Ball instead of scanning it?
For example I want to calibrate a disk, that isn't going to work if it tries to scan the sphere.
Thanks
Jon
