Sit your inclinometer (if it has a flat base) in the mount head saddle, where you'd normally secure your dovetail and rings.
Once you adjusted the latitude screws to bring the reading to your local latitude, you can put the scope on and fine tune from there during drift align.
You might be surprised how inaccurate your mount's lat scale is once you've got your actual "real" latitude set from drift aligning.
Mine was out by a full 6 degrees
