Just look at an accredited lab that does 3rd party calibrations or inspections. They will inspect and certify the bar. Honestly though $300 isnt that out of line considering it is alot cheaper then the $1500-$2500 it costs to calibrate the arm along with the downtime in not having the arm available.
I also know that some people will buy additional bars and just have them due at opposite years so that they always have a standard.
