Mitutoyo calipers are precision instruments, and seeing flashing dashes on the display can be alarming. This usually indicates a problem that needs addressing. This guide will troubleshoot common causes of flashing dashes on your Mitutoyo caliper and provide solutions to get your measurements back on track.
Understanding the Flashing Dash Error
The flashing dashes on a Mitutoyo caliper's digital display aren't a single, unified error message. The context—what the caliper is doing, what actions preceded the error, and the specific model—is crucial for accurate diagnosis. However, several underlying issues often lead to this symptom.
Common Causes of Flashing Dashes
-
Low Battery: This is the most frequent culprit. The flashing dashes often signal that the battery is depleted and needs replacing. Check your caliper's manual for the correct battery type and replacement procedure.
-
Sensor Issues: Mitutoyo calipers rely on sensitive sensors to detect jaw movement and translate that into measurements. Dirt, debris, or damage to these sensors can cause erratic readings or the flashing dash error. Cleaning the jaws and sensors is a critical first step.
-
Overload: Attempting to measure something exceeding the caliper's capacity can trigger this error. Ensure your measurement falls within the specified range for your model.
-
Internal Malfunction: In rarer cases, the flashing dashes might indicate a more serious internal problem with the caliper's electronics. This could be due to damage from drops, impacts, or internal component failure.
-
Calibration Issues: While less common, a miscalibration can lead to unusual behavior, including flashing dashes. Refer to your caliper's manual for calibration instructions.
Troubleshooting Steps
Follow these steps systematically to diagnose and resolve the flashing dash issue:
1. Check the Battery
- Replace the battery: This is the simplest and most likely solution. Use the correct battery type as specified in your caliper's instruction manual. Ensure proper polarity when installing the new battery.
2. Clean the Jaws and Sensors
- Inspect for debris: Carefully examine the caliper's jaws and the sensor areas for any dirt, dust, oil, or other debris. Use a soft brush or compressed air to gently clean these areas. Avoid using harsh chemicals or abrasive materials.
3. Verify Measurement Range
- Check the limits: Ensure the object you're measuring falls within the specified measurement range of your Mitutoyo caliper. Attempting to measure something outside this range can damage the instrument or lead to errors.
4. Inspect for Physical Damage
- Examine the caliper: Carefully inspect the caliper for any signs of physical damage such as cracks, bends, or loose parts. Even minor damage can affect its functionality.
5. Attempt to Recalibrate (If Applicable)
- Consult your manual: Some Mitutoyo caliper models allow for user calibration. Refer to your instruction manual for the specific procedure. Improper calibration can worsen the issue, so proceed with caution.
6. Contact Mitutoyo Support
If you've exhausted the above steps and the flashing dashes persist, contact Mitutoyo customer support or an authorized service center. They can diagnose more complex problems and provide appropriate repair or replacement options.
Preventing Future Issues
- Regular Cleaning: Clean your caliper regularly to prevent debris from interfering with the sensors.
- Proper Storage: Store your caliper in a safe, dry place to prevent damage.
- Avoid Overload: Always ensure the object being measured is within the caliper's capacity.
- Careful Handling: Handle your caliper with care to avoid drops or impacts.
By following these troubleshooting steps, you should be able to resolve the flashing dash error on your Mitutoyo caliper and restore its functionality. Remember to always refer to your caliper's specific instruction manual for detailed information and safety precautions.
