The main object of such regulation is to ensure standardized procedures for calibration acceptable to all stakeholders, transparency in the whole procedure, a...

  We calibrate a weighing device to understand how it behaves but we adjust the device to change its behavior. So to change the behavior of something firstly, we need to find how it is behaving by calibration and then we can adjust the same. It is important to find the device’s behavior before making any changes to its behavior. Therefore, it is reasonable and common to calibrate a weighing device without adjusting it. A relationship is developed between a known value (standard) and a measured value with the help of calibration.  Adjusting a balance means that you are intervening in the weighing system, to make sure that the display is set to show the correct nominal value. And Calibration, on the other hand, you are testing whether the display is correct and documenting any deviation.  For all units of measurement, there are some standards established as the basis for a particular unit.  In the context of weighing devices, standards come in the form of Test Weights....
