Scale Calibration for Getting Accurate Measurements

A scale is a measuring tool to determine the weight or mass of an object. A spring scale measures the weight with a spring range shift under load. Comparing the torque balance on the arm because the weight of the sample to the torque on the arm as a standard reference weight using a horizontal lever. The balance is different from the scales, the balance measure the mass, while the scale measures the weight. Scales used in industrial and commercial applications, and products from feathers to loaded tractor-trailers that are sold by weight. Specialty medical scale and bathroom scales used for measuring human body weight.

Scale Calibration
Scale calibration is the process used to ensure that the weight scale is to provide accurate information. To scale commercial use, calibration may be needed every few weeks or months, to confirm that the scales are still hard to accurately, while the scale of the house may be left uncalibrated for quite a long time

Scales began to show an accurate weight for various reasons. Sometimes the scale components become worn, change to read, and environmental factors may play a role as well. For example, the scale of many who do not perform well in cold air, and the scale calibrated to work in an environment such as a bakery; warm and humid conditions may be turned off if brought to a cold store room. The more the scale used, the more likely it is that inaccuracies will arise.

The best way to calibrate the scale is to use a known weight to see if it returns the correct measurement scale. Some companies manufacture special weight to be used in the calibration scale, but it is also possible to use something like a sack of flour, a set of barbells, or other heavy objects that must be known. To calibrate the scale, the weight is set on a scale and read the note. Furthermore, the scale can be adjusted until it yields the correct weight measurement.

Some scales adjusted only with screws or levers that can be moved. Digital scales may have a special key used in the calibration scale. Owner's manual for the scale usually provides specific information on calibration.

Most people use different weights for a calibration scale to confirm that the scale is correct within some range. Some scales may be less accurate at low load, in terms of adjustments to the low weight on the scale can get rid of the scale at a higher weight.

  1. Hi friends,

    Very good site you have created. Calibration of a scale is a procedure in which a licensed scale technician uses a known cal test weight, to test and adjust the response of a mechanical or electronic weighing system. I like your site it is very informative. Thanks a lot for creating this type of valuable site...
