3. Setup
- Unpacking: Carefully remove the dial test indicator and all accessories from its packaging. Inspect for any visible damage.
- Mounting: Securely attach the indicator to a stable stand or fixture using the provided clamp ring and stem. Ensure the mounting is rigid to prevent measurement errors due to vibration or movement.
- Contact Point Installation: Ensure the contact point is firmly screwed into the lever arm. The effective length of the contact point is crucial for accurate readings and is typically indicated on the dial face.
- Positioning: Position the indicator so that the contact point is perpendicular to the surface being measured. Apply slight pre-load to the contact point to ensure consistent contact and allow for bidirectional measurement.
- Zeroing: Rotate the outer bezel to align the '0' mark on the dial with the indicator needle. This establishes the reference point for your measurements.
4. Operating Instructions
The Mitutoyo 513-401-10E is designed for precise comparative measurements. Follow these steps for accurate operation:
- Establish Reference: Place the contact point on a known reference surface or datum point. Adjust the indicator's position until the needle is within the measurement range and then zero the dial by rotating the bezel.
- Perform Measurement: Move the indicator's contact point across the surface or feature to be measured. The needle will deflect, indicating variations from the zero reference point.
- Read the Dial: The dial is graduated in 0.001 mm increments. Each major division (e.g., 10, 20) represents 0.01 mm. The total measurement range is 0.14 mm. Observe the needle's movement to determine the deviation.
- Bidirectional Measurement: This indicator supports bidirectional measurement, meaning it can measure deviations in both directions from the reference point. The inspection certificate confirms this capability.
- Repeatability: For critical measurements, perform multiple readings at the same point to ensure consistency and verify the instrument's repeatability.
Note: Always ensure the contact point is clean and free from debris before and during measurements to maintain accuracy.
5. Maintenance
Proper maintenance is crucial for preserving the accuracy and lifespan of your Mitutoyo Dial Test Indicator.
- Cleaning: After each use, gently wipe the indicator body and contact point with a clean, soft cloth. For stubborn dirt, a cloth lightly dampened with isopropyl alcohol can be used. Avoid harsh chemicals or abrasive materials.
- Storage: Store the indicator in its protective case when not in use. Keep it in a dry, dust-free environment, away from direct sunlight, extreme temperatures, and corrosive substances.
- Handling: Handle the instrument with care. Avoid dropping or subjecting it to strong impacts, as this can affect its precision and internal mechanisms.
- Inspection: Periodically inspect the contact point for wear or damage. A worn contact point can lead to inaccurate readings.
- Calibration: For professional applications, regular calibration by a qualified technician is recommended to ensure continued accuracy.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Needle movement is sticky or erratic. | Dust or debris in the mechanism; insufficient lubrication; impact damage. | Clean the contact point and surrounding area. If the issue persists, professional servicing may be required. Avoid disassembling the unit. |
| Inaccurate readings. | Improper mounting; worn contact point; incorrect zeroing; temperature fluctuations. | Ensure rigid mounting and correct contact point orientation. Check contact point for wear. Re-zero the dial. Allow the instrument to acclimate to ambient temperature. |
| Dial crystal is scratched. | Abrasion during use or cleaning. | While the crystal is scratch-resistant, extreme care is still advised. If visibility is significantly impaired, consider professional replacement. |
