Rotate the gauge with your thumb and forefinger. The engagement should be free along the entire length of the thread for a correct measurement. 2. For formal use, the gauge must first be calibrated and certified by an accredited metrology body. During inspection, the gauge must be able to be manually engaged (thumb and forefinger) on at least two thread pitches for the part to be considered compliant. **Package Contents:** You will receive **1 internal thread gauge (buffer gauge)**. **Important Usage Notes:** - **Before Use:** It is recommended to have the gauge checked and certified by a metrology service before putting it into production. - **During Use:** Ensure that the tolerance class and deviation code of the thread being checked correspond to those marked on the gauge. - **After Use:** Clean the gauge, remove any residue, and store it in its dedicated case. On the workstation, carefully place it in its designated location. Avoid any impact that could damage the measuring surfaces. - **Warning:** Never force the screw or use the gauge as a cutting tool to prevent premature wear and ensure long-term accuracy. **Shipping Note:** Please note that the models shipped may be the old or new version of the product.
