Measuring weight is a crucial element in many industries. Shipping companies, grocery stores, airlines, and more depend on having accurate weight readings to determine the right price for their customers. Weight has especially come to the forefront in recent months, with one airline charging customers by the pound (or kilogram, in this case), rather than by the seat.
With such a strong emphasis on the numbers of a scale, it is more important than ever to have an accurate reading to go by. But how do you guarantee a correct result?
Test weights are a great way to make sure a scale is properly calibrated. For a visual of how they work, consider the image below. In this simple scale, the object you are weighing would be in one tray, while the test weight would be in the other. Since you already know the value of your test weight, you can judge the weight of the object in question.
For more high-tech scales, a test weight serves as a base for external recalibration when internal recalibration options are not provided. It’s important to regularly recalibrate scales to ensure an exact reading. Just make sure the test weight is not heavier than the capacity of the scale. If the scale is only capable of weighing 50lbs., don’t use a 100lb. test weight.
By keeping your scales in check, you’ll be able to accurately measure whatever you need at your next weigh-in. Whether it’s for airline passenger luggage, freight cargo, or customer groceries, test weights help ensure you have a precise number to work with.
