in theory, drop weight machine works on a piece of mass and gravity, so there should not be a need for calibration.
however, there is also a single point (or multiple depending on the design) of friction which is the rotating joint of the weight bar. after long use (or disuse) mechanical friction might develop. I'd suggest applying some lubrication as appropriate.
checking the actual value with a digital scale doesn't hurt either.
