There are a number of things that can affect the accuracy. Not backing off the spring in storage, dropping it over the years. If it is a high limit wrench 250 lbs, using it at 19 lbs it will probably not be as accurate. There are a number of YouTube videos on how to test and correct a wrench yourself.
