I have a digital angle gauge for alt, so that should be straightforward, but was not clear on the azimuth.

As in, where on the base should the 0 deg be? Can be anywhere you like really.
The way I used to do it was to have a moveable pointer for this scale.
So I would setup the scope and zero the alt (electronic angle finder) on a level surface. Determine the az coord of my alignment star and centre it in an EP. Then clip the pointer onto the base to point at this az. Next check the alt was what it should be, and then check the overall alignment by "finding" another object.
