I have a Pentax digital 1 deg., Zone VI spot meter that needs calibrations. Is there any reason why a local camera repairman couldn't do this calibration? Or, does the calibration need to be completed by someone knowedgeable about the internal modifications?

I purchased this meter a while ago in the FS section, and it reads about a stop too low.

(I know, I know . . . I should have checked it right when it arrived. )
