Calibration is the process of verifying a weighing scale’s accuracy by conducting extensive testing and comparing the data obtained with a known and accepted standard. Calibration helps in identifying an error the scale might have and rectify it. Calibration services include analyzing the scale and repairing them, if necessary, to bring the accuracy back within the acceptable error levels.
Why is Calibration Necessary?
When you use the scales on a regular basis, its accuracy may diminish and it might show erroneous readings. Regular calibration of industrial scales will help prevent the accuracy of the scale from degrading.
While regular wear and tear affects the accuracy, there are various other environmental factors which can affect the readings as well. For example, changes in climate, electrical overloads, accidents, the mishandling of the weighing scale, something falling on the scale, etc., can be detrimental to the performance of a weighing scale, eventually leading to inaccurate readings.
3 Important Reasons to Calibrate
- To Safeguard the Processes: When you weigh something, it is ideal to get accurate readings in order to maintain product safety. Inaccuracy can poses a safety hazard in the facility. For example, if you use an elevator or vehicle with a weight limit to transport goods, measuring those goods with an industrial scale that has not been recently calibrated may give an inaccurate weight. This may cause you to load more weight than the elevator or vehicle can handle, thus potentially resulting in damage or an accident.
- To Minimize Costs from Manufacturing Errors: An uncalibrated scale can cause issues by giving inaccurate readings. For example, delivering an accurate amount of goods is dependent on the scale weighing within tolerance. An uncalibrated scale that is not weighing out components correctly could also lead to defects in a production process.
- To Maintain Regulatory Compliance: Scales in any manufacturing business fall under regulatory compliance standards. If you use and operate scales outside of regulatory tolerances, you may be subjected to fines and penalties.
Signs That Your Scales Need Calibration
- Shows Incorrect Pre-defined Weight: When you apply a known weight on the scale and the indicator doesn’t show the exact measure of the applied weight, it is a good indicator it is time for calibrate your scale.
- Doesn’t Show Zero Reading: The scale should display ‘Zero’ on the indicator display when nothing is kept on it. If it doesn’t, the scale could be out of calibration.
- Loose Parts: If there are any noticeable loose fittings it could cause your scale to give inaccurate readings.
5 Benefits of Calibration
- Helps you maintain accurate weight measurements.
- Ensures that all the weighing equipment is fit for use and provides results that have a minimal deviation from the accepted standards.
- Helps you avoid penalties and legal action.
- Ensures that your business adheres to all relevant regulations with respect to the weight of products, vehicles and other objects weighed.
- Helps in maintaining a positive brand image when you provide the customers and business stakeholders with accurate product data.
If you calibrate your instruments regularly you can be more confident that your scale is weighing correctly. If having your scales maintained and calibrated is something you are interested in, please contact us at Quality Scales Unlimited.
