Nøglekomponenter:
- Opkaldsindikator: Displays the measurement with fine graduations in inches.
- Grebhåndtag: Ergonomically designed for comfortable and stable handling.
- Thumb Trigger: Used to lift the contact point for inserting the workpiece.
- Kontakt punkt: The movable measuring surface, ceramic for corrosion resistance.
- Ambolt: The fixed measuring surface, flat and ceramic for corrosion resistance.
- Ramme: The main body of the gauge, providing structural integrity.
3. Opsætning
Before taking measurements, ensure the gauge is properly prepared and calibrated.
- Udpakning: Carefully remove the gauge from its packaging. Inspect for any visible damage.
- Rensning: Gently wipe the contact point and anvil with a clean, lint-free cloth to remove any dust or debris. Avoid using harsh chemicals.
- Nul indstilling:
- Ensure the contact point and anvil are clean and free of obstructions.
- Release the thumb trigger, allowing the contact point to rest gently on the anvil.
- Rotate the outer bezel of the dial indicator until the large needle points exactly to '0'.
- If the needle does not return precisely to zero after several attempts, the gauge may require professional calibration.
4. Betjeningsvejledning
Follow these steps to take accurate thickness measurements:
- Forbered emnet: Ensure the material to be measured is clean, flat, and free of wrinkles or deformities.
- Lift the Contact Point: Press the thumb trigger to raise the movable contact point, creating a gap between the contact point and the anvil.
- Insert the Workpiece: Carefully slide the material to be measured into the gap, ensuring it lies flat on the anvil.
- Slip aftrækkeren: Gently release the thumb trigger, allowing the contact point to rest on the material. The spring-loaded spindle ensures consistent measuring force (less than 1.4N).
- Læs målingen: Observe the position of the large needle on the dial indicator. The reading directly indicates the thickness of the material in inches. The small sub-dial indicates revolutions of the main needle, useful for ranges exceeding one full rotation (though this model has a limited range, it's good practice to note).
- Gentag målinger: For critical applications, take several measurements at different points on the material to account for variations.
Note: Always handle the gauge with care to avoid dropping or impacting it, which can affect its accuracy.
5. Vedligeholdelse
Proper maintenance ensures the longevity and accuracy of your Mitutoyo 7326S Dial Thickness Gauge.
- Rensning: After each use, wipe the gauge, especially the measuring surfaces (contact point and anvil), with a clean, soft, lint-free cloth. If necessary, use a small amount of instrument cleaning fluid on the cloth, but avoid direct application to the gauge.
- Opbevaring: Store the gauge in its original protective case in a dry, clean environment, away from direct sunlight, extreme temperatures, and corrosive substances.
- Håndtering: Avoid dropping or subjecting the gauge to shock. Do not force the spindle or apply excessive pressure during measurement.
- Kalibrering: Regular calibration by a qualified technician is recommended to maintain accuracy, especially if the gauge is used frequently or for critical measurements.
- Smøring: The internal mechanisms are factory-lubricated. Do not attempt to lubricate the gauge yourself unless specifically instructed by Mitutoyo service personnel.
6. Fejlfinding
This section addresses common issues you might encounter with your dial thickness gauge.
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Needle does not return to zero. | Dust or debris on measuring surfaces; gauge out of calibration; bent spindle. | Clean contact point and anvil. Re-zero the gauge. If problem persists, seek professional calibration or repair. |
| Inkonsekvente aflæsninger. | Workpiece not flat; improper handling; gauge not stable; worn measuring surfaces. | Ensure workpiece is flat. Hold gauge steadily. Clean surfaces. If wear is suspected, professional inspection is needed. |
| Gauge feels stiff or sticky. | Accumulated dirt; lack of lubrication (rare for sealed units). | Clean thoroughly. Do not attempt to lubricate. Contact service if problem persists. |
