Before we describe how to calibrate precision scales and analytical balances we’ll tell you why you need to calibrate these precision weighing devices. In many instances it’s required by law but in all cases calibrating these instruments, especially those used in R&D labs and other demanding applications, should be conducted on a regular basis as a part of good laboratory practices (GLP).
Calibration exercises apply to other types of scales for many of the same reasons. Buyers and sellers of products want to get and give “fair measure.” For the purpose of this post we’ll focus on precision scales and analytical balances where deviations between actual weight and displayed weight can be unacceptable. Calibration exercises are aimed at making the scales as accurate as possible.
In addition to explaining how to calibrate these weighing instruments this post first goes into detail … Read the rest
