How Does the Scale Calibration Procedure Work?
A known standard or certified mass is placed on your scale. That weight reading is recorded. If the weight readings match the standards applied or fall within the calibration tolerance (more about that below), the scale does not need any adjustment. If the weight readings do not match or fall within the tolerance, service will likely be needed to restore the scale to the acceptable state of accuracy.
What Is Calibration Tolerance and How Do I Calculate It?
Calibration tolerance is defined by the International Society of Automation (ISA) as “permissible deviation from a specified value; may be expressed in measurement units, percent of span, or percent of reading.“ When it comes to scale calibration, tolerance is the amount the weight reading on your scale can differ from the nominal value of the mass standard that has optimal accuracy. Of course, ideally, everything would match up perfectly. Since that’s not the case, tolerance guides ensure that your scale is measuring weights within a range that will not negatively affect your business.
What Is Legal-for-Trade Calibration?
Commercial scales require legal-for-trade calibration. That means the scale needs to be calibrated according to the standards found in “Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices” — also known as “Handbook 44.” This comprehensive list of requirements is mandatory for all scales used for commercial purposes. A new version is published every year by the National Institute of Standards and Technology (NIST).
