Answer from Ningbo Changshi: The accuracy of a tension meter is critical for both safety and quality, so regular calibration is non-negotiable. While the exact frequency depends on the severity and frequency of use, industry standards generally recommend annual calibration. For meters used in extreme conditions or on highly critical projects, more frequent calibration—quarterly or even monthly—may be necessary.

Best practices for maintenance include:

• Keep it clean: Regularly wipe down the meter to remove dirt, mud, and debris that can affect its accuracy.

• Store it properly: Always store the meter in its protective case when not in use to prevent physical damage and protect it from moisture.

• Visual inspection: Before each use, visually inspect the meter for any signs of physical damage, such as bent rollers, a cracked display, or a faulty connection.

• Professional service: Only have your meter calibrated and serviced by qualified professionals who use standards traceable to national laboratories, ensuring the highest level of accuracy and compliance.

By adhering to these practices, you can significantly extend the lifespan of your tension meter and ensure it provides reliable readings on every job.
