Wiha Torque Screwdriver Calibration: Frequently Asked Questions
Here are some frequently asked questions about calibrating your Wiha torque screwdriver to maintain accuracy and extend its lifespan.
How often should I calibrate my Wiha torque screwdriver?
Wiha recommends calibrating your torque screwdriver at least once a year, or more frequently depending on usage. Heavy or constant use necessitates more frequent wiha torque screwdriver calibration to ensure continued precision.
What tools do I need to perform Wiha torque screwdriver calibration?
You’ll need a torque analyzer or calibrated torque sensor, the appropriate adapter for your screwdriver, and the manufacturer’s calibration specifications for your specific Wiha torque screwdriver model. Check your screwdriver’s documentation.
Can I calibrate my Wiha torque screwdriver myself, or should I send it in?
While you can perform wiha torque screwdriver calibration yourself with the proper equipment and understanding of the process, many users prefer to send it to a certified calibration lab. This ensures traceable and accurate results.
What happens if I don’t calibrate my Wiha torque screwdriver?
Over time, the internal components of your torque screwdriver can drift, leading to inaccurate torque readings. This can result in under-tightening or over-tightening fasteners, potentially causing damage or failure. Regular wiha torque screwdriver calibration prevents these issues.
Alright, now you’re equipped to keep your wiha torque screwdriver calibration in tip-top shape! Go forth and tighten those screws with confidence. Happy calibrating!
