When you use a scale, you want it to be as accurate as possible whether you’ve never used it before or you’ve had it for years. Unfortunately, scales can lose accuracy for multiple reasons and need to be adjusted to regain the highest level of accuracy possible. This process is called calibration. Knowing when and why to calibrate your scale can help you keep your scale accurate no matter when you use it.
What is scale calibration?
Calibration is a way to find a relationship between two unknown quantities. The process uses one quantity that is known, which has been measured by a measurement device and compares that known quantity on a second device under similar circumstances. If the two devices have different calibrations, the measure of the known quantity will be different on those two devices. When that occurs, the device with the known correctness that assigned the measure to the known quantity is the standard for expectations. The other device is then compared to this standard and, if needed, the second device is adjusted to match the standard. The comparison and adjustment is scale calibration.
Why do scales need to be calibrated?
The main reason that scales need to be calibrated is to ensure the highest level of accuracy and reliability in measurements. Even if a device is calibrated at the start of its life, time and use can impact the accuracy of your scale. Calibration should be part of the regular maintenance of your scale to maintain accuracy. That accuracy helps ensure you can rely on your scale each time you use it.
In addition, calibration can help identify potential problems with your scale early so they can be repaired or replaced. That keeps you from having problems with your measurements as the indication that something is wrong with your scale. As a result, you save time and effort when you know that your scale is calibrated and you can rely on its measurements as accurate.
When do scales need to be calibrated?
Several instances that require scale calibration. The most crucial calibration occurs when your scale is new. Before you start to use it, calibration ensures you are starting with an accurate measurement. However, you should also calibrate your scale:
- After a modification or repair to the scale
- Before a crucial measurement is taken
- After a crucial measurement is taken
- After a shock, damage, or another event that could damage or impact the scale’s accuracy
- Periodically and regularly as part of routine scale maintenance
By calibrating scales at these times, you will know that all your measurements are as accurate as possible no matter when you use your scale.
Accuracy is always an essential aspect of a commercial scale no matter why you need it. Whether you have a new scale that needs to be calibrated before use, you have an important measurement to take, or it’s time for regular maintenance, calibration services can help ensure the accuracy of your scale.
