The weighing instrument should be switched on at least 30 minutes before the calibration. Make sure you have enough weights for the calibration procedure available. Typically, the whole measurement range is calibrated and the calibration is performed in the location where the instrument is being used. You should find out the technical characteristics of the weighing instrument (max weight, d value), the accuracy requirement (max error allowed and uncertainty) and what to do if the calibration fails (adjustment). Preparations before calibrationīefore you can start the calibration of the weighing instrument, you should clarify a few things and get prepared. Let’s start by looking at some of the preparations you should make before the calibration and then look at the different tests you should be doing.īack to top ⇑ 1. Here is a video on how to calibrate weighing scales: To download this article in as pdf file, please click the picture below:

In this article, the main focus is to look at the practical considerations and the different tests you should perform when calibrating your weighing instruments. There are dedicated regulations for weighing instruments and their calibration (EURAMET Calibration Guide, NIST Handbook 44, OIML) more on those later in the article. Often the calibration of weighing instruments is based on a quality system (such as ISO9000), health care, traffic (air, marine) safety or forensic investigation. Many weighing instruments are used for legal measurements or measurements used as the basis for the monetary transfer and these are part of a legal or statutory verification program based on legislation. A proper metrologically traceable calibration is the only way to know how accurately weighing instruments are measuring. We all see weighing instruments in our everyday life around us, for instance, when we visit a grocery store and weigh vegetables.Īs with any measurement instruments, weighing instruments should also be calibrated regularly to assure that they are measuring correctly and accurately. While some industrial weighing instruments are very large ones that measure, for example, the mass of trucks. Some weighing instruments are small laboratory instruments measuring a few grams and are very accurate. Weighing instruments/scales/balances, are widely used in industry for various measurements. I will be mainly using the term “ weighing instrument” in this article. Weighing scales, weighing instruments, weighing balances…ĭifferent resources are using different terminology. Update February 2019: We made an educational video on weighing scale calibration, you can find that in this link:

In this article, I look at the practical considerations and the different tests you should perform when calibrating your weighing scales/instruments/balances.
