3. セットアップ

Proper setup is essential for accurate measurements. Follow these steps to prepare your Mitutoyo 2416S-10 Dial Indicator for use:

1. 取り付け: Secure the dial indicator using its rear lug. The lug allows for mounting from the back of the indicator onto a suitable stand or fixture. Ensure the mounting is firm and stable to prevent any movement during measurement.
2. Stem Installation: The indicator features a 3/8 inch diameter stem. Insert the stem into a compatible clamping mechanism on your measurement stand. The stem's design provides a long clamping range, allowing for flexible positioning.
3. 連絡先: The contact point has a #4-48 UNF thread. Ensure it is clean and free from debris. If replacing, use only compatible Mitutoyo contact points.
4. ポジショニング: Position the indicator so that its spindle is perpendicular to the surface being measured. This ensures that the displacement is measured along the indicator's axis for accurate readings.

4. 操作手順

To obtain accurate measurements with your dial indicator, follow these operating guidelines:

1. ゼロ設定： Before taking a measurement, bring the contact point into gentle contact with a known reference surface or the lowest point of the feature to be measured. Rotate the bezel to align the '0' mark on the dial with the indicator hand.
2. 測定： Carefully move the indicator or the workpiece to measure the desired variation. The indicator hand will move clockwise or counter-clockwise, showing the displacement.
3. 文字盤の読み方: The 2416S-10 is a continuous dial with a 0-100 reading. Each major division typically represents 0.001 inches. The total range is 1 inch, meaning the hand will complete 10 revolutions for a 1-inch displacement.
4. Measuring Force: The indicator operates with a measuring force of 1.8 Newtons (N) or less. Apply consistent and minimal force to avoid deforming the workpiece or affecting measurement accuracy.
5. Limit Markers: Utilize the rotating limit markers on the bezel to set tolerance limits for quick visual inspection during repetitive measurements.

5. メンテナンス

Proper maintenance ensures the longevity and accuracy of your Mitutoyo dial indicator:

• クリーニング： After each use, wipe the indicator clean with a soft, lint-free cloth. For stubborn grime, use a mild cleaning solution specifically designed for precision instruments, applied sparingly to the cloth. Avoid harsh chemicals or solvents.
• ストレージ： Store the indicator in its protective case when not in use. Keep it in a dry, temperature-controlled environment, away from direct sunlight, dust, and excessive vibrations.
• 検査： Periodically inspect the contact point for wear or damage. A worn contact point can lead to inaccurate readings. Check the spindle for smooth movement and ensure the bezel rotates freely.
• 防塵・防水性能: The stem design offers resistance to dust and water. However, the instrument is not fully waterproof. Avoid submerging it in liquids or exposing it to excessive moisture.
• 較正： For critical applications, regular calibration by a qualified technician is recommended to maintain certified accuracy.

6。 トラブルシューティング

If you encounter issues with your Mitutoyo 2416S-10 Dial Indicator, consider the following:

• 不正確な読み取り:
  • Ensure the indicator is securely mounted and not vibrating.
  • Verify the contact point is clean and not worn.
  • Check that the spindle moves freely without sticking.
  • Confirm the indicator was properly zeroed against a stable reference.
• Sticking Spindle:
  • Clean the spindle thoroughly to remove any dust or debris.
  • Avoid applying excessive force that could bend or damage the spindle.
• Dial Hand Not Moving:
  • Check if the contact point is making proper contact with the surface.
  • Ensure the indicator is not locked or jammed.

For persistent issues or repairs, please contact Mitutoyo customer support or an authorized service center.
