The importance of balance and scale calibrations – A&D Weighing

A&D Weighing, is one of the industry leaders in the supply and servicing of electronic weighing scales, laboratory balances, and measurement systems. We provide calibration services across a wide range of weighing equipment and instruments. Calibration is a ‘quantitative’ test that is carried out to check the accurate reading of a reference weight, balance or scale. Calibration involves checking the reading given on the balance against a standard known-mass calibration weight. Regular calibration of your scales or balances is the best way to ensure measurements taken are accurate.

Why is routine calibration important for your scales and balances?

Routine calibration of your digital scales is the most effective way to prolong your scale’s quality and ensures you are taking accurate measurements each and every time. Calibrating an electronic scale or balance ensures the reliability and repeatability of weighing results and maintains its accuracy.

Balance and scale calibration is important to ensure measurement accuracy, which is critical in various applications as it can affect not only the cost, but also the quality of the product. Regular calibration can also extend the life of the machine, which is why we recommend periodic testing of your product.

Another important factor is that this process is critical for compliance with internal and external auditing. There are several legislative requirements for measurement calibration. As leaders in the weighing industry, A&D provides sound calibration services to prolong the life of balances, scales, and instruments.

What happens if I don’t calibrate my scale?

Balances and scales can lose their accuracy and malfunction over time, and without frequent calibration, it can lead to considerable limitations in performance and inaccurate readings. Through exposure to extreme temperatures and other external factors, over time, critical equipment components are prone to mechanical stress, drifting, and wear and tear. Through periodic recalibration, weight accuracy is established, which further ensures the quality of measurement results. Although drift cannot always be eliminated, it can be detected through frequent calibration. This is why it is essential to have frequent routine testing. Not only does routine testing cut out measuring guesswork, but it also improves the life span of your scale and weighing accuracy.

Working in high-risk environments

A&D recommends recalibrations to be conducted on a regular basis, to ensure optimal weighing measurements. Undetected drift and unplanned errors due to environmental changes, can become problematic. Equipment should be calibrated routinely to avoid product recalls, audit issues, unscheduled downtime and inferior product quality. Uncalibrated equipment can also lead to hidden costs due to the balance or scale being more costly than the calibration itself.

Tolerances applicable to balance calibration

Through the process of calibration, tolerances are used to determine whether process requirements are acceptable. Set criteria will determine a pass or fail of the balance equipment. These tolerances originate from specific legislation and sources including legal tolerances, manufacture tolerances, and process tolerances. Therefore, it is important to understand the legal obligations and implications for scales and balances that require calibration.

Differences between tolerances and adjustment

Knowing the differences between tolerances and adjustment is important. Tolerances in the manufacturing process determines the reliability of the product. Tolerances identify the relationship between quantity values and measurement uncertainty to identify how much room for error is available. Adjustment of equipment and devices is the setting or the alignment of the scale, measuring tool or instrument.
