Scales and Dials: Is Constant Calibration Important?

Updated on September 29, 2015

Whether you are using digital scales or you are using dials that are old-fashioned ones, you should be aware that calibrating these from time to time is required. Calibration is the act of determining whether or not your measuring equipment are still accurate, and are adjusted when these need to be. The frequency of calibration is something that people find difficult to determine, and in order to do so, a few factors need to be considered.

For starters, you need to know how often these equipment will be used from the moment these are purchased and actually utilized. This will help those in charge of these equipment to schedule regular calibration and checking of such items for wear and tear. You also need to know what the manufacturer says when it comes to the calibration of such equipment, since they know better in terms of how frequently these need to be checked for accuracy and what factors can affect this.

Why Calibration is Important

Why is the calibration of equipment important and why should you not ignore the suggestion of regular checking and adjusting of these measuring tools? Apart from the fact that you need to get accurate readings from these things for the sake of getting the real measurements from these, there are also other problems that come with not getting the accurate readings from these. Let us enumerate some of them:

  • Requirements for customer, processing and industry accuracy – when measuring or weighing out product for sale, you need to ensure that what you measure out is accurate. If there is even a small discrepancy in the actual weight and what is being shown on your equipment, you will end up “cheating” your clientele, particularly if these clients regularly purchase from you. Your customers will want to ensure that they are getting what is due them, which is why calibration is required regularly.
  • Requirements for regulation or contract needs – this is similar to the aforementioned need for accuracy for customer and processing needs since this mandates that your scales or measuring equipment be accurate to fulfill contract or regulation requirements. If your scales or dials are not accurate and not calibrated regularly, discrepancies can go against what is being stated in contracts or regulations, which can cause problems. This can also bring about problems when it comes to ISO standards as well as when industry regulations mandate specific quality control guidelines to be followed.

Reasons Why Scales and Dials May Require Frequent Calibration

Frequent calibration is needed when measuring equipment, or any equipment that have scales and dials on them for that matter, are exposed to elements that may decrease their accuracy. One such element that can affect the accuracy of these measuring tools is the weather. If your equipment is exposed to various weather conditions, these will require calibration to return them to their original accurate states.

Another thing that may affect the way these measuring gauges read is where these are stored. Not all storage units are conveniently near where these things are to be used, hence any handling and transporting may affect accuracy as well, hence the need for calibration and checking. You should also make sure that when these are being moved from one place to another that the person or persons handling these know what they are doing. Mishandling and mishaps, like the dropping of the equipment that have these scales and dials, may also affect how these operate and the accuracy that these are supposed to have.

It is also a known fact that time plays a huge factor when it comes to the condition of anything anyone uses. No matter what item it may be, time will have an effect on it, and this is why care is required. For scales and dials, as well as the equipment that these are used on, checking and maintenance is required on a regular basis to ensure that these show you exactly what they need to show you.

Take for example vehicles and speedometers. If you don’t check on these periodically, and have these calibrated by certified technicians, you may be running at a faster speed and your speedometer may show you that your speed is below what you are actually running. This can cause accidents and may even get you in trouble with the law for speeding. Constant use will also bring about changes in how these things read, so the more you use a piece of equipment, the more frequently the calibration process should be enacted.
