Good Weighing Practice™ (GWP®) and Validation
Can digital weighing scales be wrong?
Yes, any scale can be wrong. If a scale is connected to a power source, it will register a weight. Most people trust that that weight is correct, when in fact it could be wrong. Regular calibration is the best way to ensure weighing accuracy.
How do I know if my weighing scale is accurate?
Regular calibration is the best way to ensure your scale is accurate. Additionally, systems such as GWP®, the Good Weighing Practice ™, help to ensure scales are fit-for-purpose. This means they offer the ideal weighing range and desired accuracy levels based on your intended use.
