What should be done with a micro-adjusting torque wrench after use?

• A. It should be stored with the battery removed.
• B. It should be stored in a damp area.
• C. It should be calibrated every day.
• D. It should be calibrated at regular intervals.

Answer: (D)

Precision torque tools can drift a bit with use, temperature changes, and normal wear. To keep the readings trustworthy, they should be calibrated at regular intervals according to the manufacturer’s guidance. This periodic calibration ensures the wrench still delivers the exact torque you set, which is crucial for fasteners that require tight but precise clamping. Daily recalibration is typically unnecessary unless the tool is used in high-stakes or harsh conditions, while storing conditions matter less than maintaining calibration.
