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 help you troubleshoot and resolve the issue of flashing dashes on your Mitutoyo caliper, ensuring you can quickly get back to accurate measurements.
Understanding the Flashing Dash Error
The flashing dashes on your Mitutoyo caliper's display aren't a specific error code; rather, it's a general indicator that something is amiss. It often signifies a problem preventing the caliper from functioning correctly. Several factors could cause this, ranging from simple issues to more complex malfunctions.
Common Causes of Flashing Dashes and How to Fix Them
Let's explore the most frequent culprits behind this frustrating problem and the steps to rectify them:
1. Low Battery
This is the most common reason for flashing dashes. Mitutoyo calipers require sufficient power to operate correctly.
- Solution: Replace the batteries. Consult your caliper's manual for the correct battery type and installation procedure. Ensure you use fresh, high-quality batteries.
2. Battery Contact Issues
Even with fresh batteries, poor contact can prevent the caliper from powering up correctly.
- Solution: Carefully open the battery compartment and inspect the battery contacts for corrosion or dirt. Clean them gently with a soft cloth or cotton swab and reinsert the batteries, ensuring a secure connection.
3. Faulty Sensor
The caliper uses a sensor to detect the jaw position. A malfunctioning sensor can trigger the flashing dashes error.
- Solution: This issue requires more technical expertise. If cleaning the sensor (if accessible) doesn't resolve the problem, you'll likely need to contact Mitutoyo customer service or a qualified repair technician. Attempting repairs yourself could void your warranty.
4. Internal Circuit Problems
Internal circuit failures can be more complex and require professional attention.
- Solution: Contact Mitutoyo customer service or an authorized repair center for diagnosis and repair. Provide them with the model number of your caliper for accurate assistance.
5. Calibration Issues
While less frequent, severe calibration problems might manifest as flashing dashes. This usually indicates a more serious internal problem.
- Solution: Do not attempt to recalibrate the caliper yourself. This should only be done by trained professionals using specialized equipment. Contact Mitutoyo support or a qualified repair technician.
6. Overloading
Attempting to measure objects exceeding the caliper's capacity can also lead to error messages, sometimes appearing as flashing dashes.
- Solution: Ensure that the object you're measuring is within the specified range of your Mitutoyo caliper. Refer to your caliper's manual for its measurement capacity.
Preventative Measures
To minimize the chances of encountering flashing dashes, consider these preventative measures:
- Regular Battery Checks: Monitor your battery level frequently.
- Proper Handling: Avoid dropping or mishandling your caliper to prevent damage.
- Environmental Protection: Keep your caliper clean and dry to prevent corrosion.
- Regular Calibration (by a professional): Schedule professional calibration according to Mitutoyo's recommendations to ensure long-term accuracy.
When to Seek Professional Help
If you've tried the basic troubleshooting steps and the flashing dashes persist, it's best to contact Mitutoyo customer service or a qualified repair technician. Attempting more complex repairs yourself could cause further damage and potentially void any warranty. Remember to always consult your caliper's instruction manual for specific troubleshooting guidance.
