Maintaining calibration is crucial to ensure the accuracy and reliability of your semi-scales. It's recommended to calibrate your truck scale every 6 to 12 months, but this can vary based on the type of scale, the cargo being weighed, and any regulatory requirements in your industry. If you frequently transport heavy loads, you may need to calibrate your Certified weight scales more frequently to compensate for the extra strain placed on them. Keeping up with regular calibration checks can help prevent inaccurate readings and ensure optimal performance.
