Mine are close enough now that I am judging "equal" mostly based on friction on a leveling paper. One approach that might work is to loosen both completely so there is no stiction then turn the table lead screw to run the table up so they both rest on it... then tighten the set screws. Or you might be lucky and get a unit that was properly calibrated.
And hope the table is properly leveled...
