Obrázek 1: INSIZE 3281-6 Screw Thread Micrometer. This image displays the complete micrometer, highlighting its U-shaped frame, the anvil on the left, the spindle on the right with its measuring tip, the thimble with graduations, and the ratchet stop at the far right. The INSIZE logo and measurement range are visible on the frame.

Klíčové vlastnosti:

• Measures pitch diameter of screw threads.
• Graduation: 0.001 inch.
• Equipped with a ratchet stop for consistent measuring force.
• Supplied with 60° setting standards (for ranges greater than 1 inch).
• Optional accessory: 55° setting standards (part no. 3281-Sp).
• Measuring tips (part no. 7381) are interchangeable.

3. Nastavení

Before initial use, ensure the micrometer is clean and free from any debris.

3.1 Nastavení nuly

1. Clean the measuring faces of the anvil and spindle with a lint-free cloth.
2. For micrometers with a range greater than 0-1 inch (like this 5-6 inch model), use the appropriate setting standard (60° standard supplied).
3. Place the setting standard between the measuring faces.
4. Turn the thimble until the measuring faces gently contact the setting standard. Use the ratchet stop to apply consistent, light pressure until it clicks 2-3 times.
5. Check if the zero line on the thimble aligns perfectly with the datum line on the sleeve.
6. If misalignment occurs, use the supplied wrench to adjust the sleeve until the lines align. Refer to the specific instructions for your micrometer model for detailed adjustment procedures.

4. Návod k obsluze

Follow these steps for accurate measurement of screw thread pitch diameter.

1. Příprava: Ensure the micrometer and the workpiece are clean and at a stable temperature.
2. Umístění: Hold the micrometer firmly. Position the screw thread between the specialized measuring tips (anvil and spindle). Ensure the tips engage correctly with the thread flanks.
3. Měření: Slowly turn the thimble until the measuring tips make gentle contact with the thread. Continue turning the ratchet stop until it clicks 2-3 times. This ensures consistent measuring force.
4. Čtení: Lock the spindle if your micrometer has a locking mechanism. Read the measurement from the sleeve and thimble scales.
5. Výklad:
   • Each numbered line on the sleeve represents 0.100 inch.
   • Each unnumbered line between the numbered lines represents 0.025 inch.
   • Each graduation on the thimble represents 0.001 inch.
   • Add the readings from the sleeve and thimble to get the total measurement.
6. Opakovatelnost: For critical measurements, take multiple readings and average them to minimize errors.

5. Údržba

Proper maintenance ensures the accuracy and longevity of your micrometer.

• Čištění: After each use, wipe the micrometer clean with a soft, lint-free cloth. For stubborn grime, use a small amount of instrument cleaning fluid, then wipe dry.
• Mazání: Periodically apply a thin film of light machine oil to the spindle thread to ensure smooth operation and prevent corrosion. Avoid over-lubrication.
• Skladování: Store the micrometer in its protective case when not in use. Keep it in a dry, temperature-controlled environment, away from direct sunlight, dust, and corrosive substances.
• Inspekce: Regularly inspect the measuring faces for wear or damage. Ensure the ratchet stop functions correctly.
• Kalibrace: For professional applications, periodic calibration by a certified laboratory is recommended to maintain accuracy.
