Parm,
No measuring needed except for the diameter of a machined bar, or two.
First, check it is cutting a short, thick bar parallel (no tailstock support). If cutting a taper, that needs addressing first - by adjusting the bed at the tailstock end until it does cut parallel.
Then do the same test with a longer rigid bar, supported by the tailstock. Adjust the tailstock position with those screws until the lathe cuts parallel. This usually done by using a long bar, thinned in the middle to leave two bobbins so that thin cuts are easily done quite quickly.
Attempting the second part without completing the first part would be a waste of time and effort.
The Raglans likely cut parallel ‘out of the box’ - the tailstock end of the bed should not be tightly affixed to the stand. Mine is virtually free at the tailstock and cuts parallel. The bed should be held just securely/firmly with a Thackeray washer - not pulled down as tight as possible.
A small amount of error in the vertical, due to wear, is relatively unimportant. Turning between centres is the ideal, of course (the headstock end should be cut in the chuck, as that will be dead centre as long as it is not removed from the chuck).
