It has been a while since my original training on calibration and we are looking to start updating our processes at the old tea company.
For years, I have been purchasing new scales in lieu of having an official 3rd party come in to check the calibration.
This year, my team asked me if this was necessary. Do we need to repurchase the scales? Do we need have someone come in to officially check the calibration on our scales?
I looked through my handbook and couldn't find an answer.
So, the question is: Is it neccessary to have an outside contractor come in to check my calibration?
