1. ການ​ຫຸ້ມ​ຫໍ່​ແລະ​ການ​ກວດ​ກາ​: Carefully remove the micrometer from its packaging. Inspect for any visible damage that may have occurred during shipping.
2. ທໍາຄວາມສະອາດ: Before first use, gently wipe all surfaces, especially the measuring faces (anvil and spindle), with a clean, lint-free cloth to remove any protective oil or dust.
3. ເງື່ອນໄຂສິ່ງແວດລ້ອມ: Ensure the measurement environment is stable in temperature and humidity to prevent thermal expansion or contraction of the instrument or workpiece.
4. Zero-Point Adjustment: Close the measuring faces completely by rotating the ratchet stop until it clicks 2-3 times. Check if the zero line on the thimble aligns perfectly with the datum line on the sleeve. If not, use the provided wrench to adjust the sleeve or thimble until alignment is achieved. Refer to the specific adjustment procedure for your model if detailed instructions are available.

5. ຄໍາແນະນໍາການດໍາເນີນງານ

Follow these steps for accurate measurement using your micrometer:

1. Clean Measuring Surfaces: Before each measurement, gently wipe the measuring surfaces (anvil and spindle) with a clean, lint-free cloth to remove any dust or oil.
2. Hold the Micrometer: Hold the micrometer by the frame, ensuring your hand does not transfer excessive heat to the instrument, which could affect accuracy.
3. ວາງຕຳແໜ່ງຊິ້ນວຽກ: Place the workpiece securely between the anvil and the spindle.
4. Advance the Spindle: Rotate the thimble or ratchet stop to advance the spindle towards the workpiece. When the spindle makes contact, continue rotating the ratchet stop until it clicks 2-3 times. This ensures a constant and repeatable measuring force.
5. Lock the Spindle (Optional): If your micrometer has a locking clamp, gently tighten it to secure the spindle position before reading, especially for larger measurements or when removing the workpiece.
6. ອ່ານການວັດແທກ: Read the measurement from the sleeve and thimble scales. For precise readings, ensure your eye is directly in line with the scale to avoid parallax error.
7. Record Measurement: Note down the measurement immediately.

6. ບໍາລຸງຮັກສາ

Proper maintenance ensures the longevity and accuracy of your micrometer:

• ທໍາຄວາມສະອາດ: After each use, wipe the micrometer clean with a dry, soft cloth. For stubborn dirt or grime, use a cloth lightly dampened with instrument cleaning oil, then wipe dry immediately.
• ການເກັບຮັກສາ: Always store the micrometer in its protective case when not in use. Keep it in a dry, temperature-stable environment, away from direct sunlight, high humidity, corrosive substances, and extreme temperatures.
• ການລະບາຍສີ: Do not apply excessive oil to the spindle or other moving parts unless specifically instructed by Mitutoyo. Over-lubrication can attract dust and debris, affecting performance.
• ການຈັດການ: Avoid dropping or subjecting the micrometer to impact, as this can damage its precision components.
• ການປັບທຽບ: Regular calibration by a qualified technician is highly recommended to maintain the instrument's accuracy, especially for critical measurements or after prolonged use.

7. ການແກ້ໄຂບັນຫາ

If you encounter issues with your micrometer, consider the following common problems and solutions:

• ການອ່ານທີ່ບໍ່ຖືກຕ້ອງ:
  • Check the zero-point adjustment. Re-adjust if necessary.
  • Ensure measuring surfaces are clean and free from debris or burrs.
  • Verify that the constant measuring force (ratchet stop) is used correctly and consistently.
  • Check for wear or damage to the measuring surfaces or spindle.
  • Ensure the workpiece is properly seated and not tilted.
• Stiff Spindle Movement:
  • Clean the spindle and internal threads to remove any accumulated dust or dried lubricant.
  • Do not force movement. If cleaning does not resolve the issue, professional servicing may be required.
• Loose Spindle Movement:
  • If the spindle feels too loose, check the friction thimble or locking clamp (if applicable) for proper engagement.
  • Excessive looseness may indicate internal wear, requiring professional inspection.
• Difficulty Reading Scale:
  • ຮັບປະກັນໃຫ້ມີແສງສະຫວ່າງພຽງພໍ.
  • Read the scale directly to avoid parallax error.
  • Clean the sleeve and thimble surfaces if they are obscured by dirt.
