Dial spring scales consist of various mechanical components, including springs, gears, and levers, that work together to provide accurate readings. Over time, these components can experience wear and tear due to repeated use. When the internal mechanisms become worn, the scale's ability to accurately measure weight is compromised. This can result in readings that are consistently too high or too low.

Solution: Regular maintenance and calibration are key to preventing mechanical wear and tear. Lubricating moving parts, checking for loose screws or connections, and ensuring proper storage can help prolong the life and accuracy of the scale.

Dial spring scales have a limited weight capacity, which is usually indicated on the scale itself. Exceeding this weight limit can cause the internal components to deform or become permanently damaged. Overloading the scale not only leads to inaccurate readings but can also render the scale unusable.

Solution: Always check the weight capacity of the scale and make sure you're within its limits. If you consistently need to measure weights near the scale's maximum capacity, consider investing in a higher-capacity scale.
