Mitutoyo calipers are precision instruments renowned for their accuracy and reliability. However, encountering flashing dashes on your Mitutoyo caliper's display can be frustrating and disruptive to your workflow. This comprehensive guide will delve into the common causes of this issue and provide practical troubleshooting steps to get your calipers back in operation. We'll cover everything from simple battery checks to more complex calibration procedures.
Understanding the Flashing Dashes Error
The flashing dashes on a Mitutoyo caliper display usually indicate a problem with the instrument's internal systems. It's not a specific error code, but rather a general indicator that something requires attention. This could range from a low battery to a more serious internal malfunction. Ignoring the flashing dashes could lead to inaccurate measurements, potentially impacting the quality of your work.
Common Causes and Troubleshooting Steps
Let's explore the most frequent reasons behind the flashing dashes and the corresponding solutions:
1. Low Battery
- Problem: The most common reason for flashing dashes is a depleted battery. Mitutoyo calipers rely on batteries to power their internal electronics, and a low charge can trigger this error.
- Solution: Replace the battery with a fresh one of the correct type and voltage specified in your caliper's manual. Ensure the battery is correctly installed, observing proper polarity. After replacing the battery, power on the caliper to see if the issue is resolved.
2. Calibration Issues
- Problem: If the caliper is significantly out of calibration, it may display flashing dashes as a warning. This often happens after a drop or impact.
- Solution: Refer to your Mitutoyo caliper's manual for the specific calibration procedure. Many models require calibration using a gauge block or other precision measuring device. Improper calibration can lead to inaccurate measurements, so follow the instructions carefully. If you're uncomfortable performing calibration yourself, seek professional assistance from a qualified technician.
3. Internal Electronic Malfunction
- Problem: Flashing dashes could signal a more serious problem within the caliper's internal electronics, such as a faulty circuit board or sensor.
- Solution: If replacing the battery and recalibrating doesn't resolve the issue, the problem is likely internal. Contact Mitutoyo's customer service or an authorized repair center for assistance. They can diagnose the problem and provide necessary repairs or replacement.
4. Sensor Problems
- Problem: The caliper's internal sensor might be damaged or dirty, preventing accurate readings and triggering the flashing dashes.
- Solution: Carefully inspect the caliper's jaws and sensor for any debris or damage. Clean the sensor gently with a soft, lint-free cloth. Avoid using harsh chemicals or abrasive materials. If the problem persists, professional repair is likely required.
Preventing Flashing Dashes in the Future
Regular maintenance and proper handling are crucial for preventing this error from recurring.
- Battery Care: Regularly check the battery level and replace it promptly when needed. Avoid leaving the caliper powered on unnecessarily.
- Proper Handling: Handle your Mitutoyo calipers carefully. Avoid dropping or impacting them, as this can damage internal components.
- Regular Cleaning: Keep your calipers clean and free from debris. Regular cleaning prevents dirt and grime from interfering with the sensor and other components.
- Periodic Calibration: Calibrate your calipers regularly, according to the manufacturer's recommendations, to ensure accuracy.
Conclusion
Flashing dashes on your Mitutoyo calipers usually indicate a problem that needs attention. By following the troubleshooting steps outlined above, you can often identify and resolve the issue quickly. Remember, if the problem persists despite your efforts, seeking professional assistance from Mitutoyo or an authorized service center is recommended to avoid further complications or damage. Maintaining your calipers properly will ensure years of accurate and reliable measurement.
