Mitutoyo calipers are precision instruments relied upon for accurate measurements across various industries. However, encountering blinking dashes on your Mitutoyo caliper's display can be frustrating and disruptive. This comprehensive guide will walk you through the common causes of this issue and provide effective troubleshooting steps to get your caliper back up and running.
Understanding the Blinking Dashes Error
The blinking dashes on a Mitutoyo caliper's display usually indicate a problem with the instrument's internal systems. It's a general error message, not a specific diagnostic code, meaning several factors could be at play. Ignoring the blinking dashes and continuing to use the caliper could lead to inaccurate measurements or further damage.
Common Causes of Blinking Dashes on Mitutoyo Calipers
Several factors can trigger the blinking dashes error. Let's explore the most frequent culprits:
1. Low Battery
The most common reason for blinking dashes is a low battery. Mitutoyo calipers rely on consistent power to function correctly. A weakening battery can cause intermittent errors, including the dreaded blinking dashes.
2. Battery Contact Issues
Even with fresh batteries, poor contact between the battery and the caliper's terminals can disrupt the power supply. Corrosion or misaligned battery compartments are frequent offenders.
3. Internal Electronic Malfunction
In some cases, the blinking dashes signal a more serious problem within the caliper's internal electronics. This could be due to:
- Overuse or mishandling: Dropping the caliper or subjecting it to excessive shock or vibration can damage internal components.
- Exposure to extreme temperatures or humidity: Operating the caliper outside its specified environmental range can lead to malfunctions.
- Internal component failure: Like any electronic device, components can fail over time due to wear and tear.
4. Software Glitch (Less Common)
While less frequent, a software glitch within the caliper's internal system could also cause the blinking dashes. This is often resolved by resetting the device.
Troubleshooting Steps: Getting Your Caliper Working Again
Follow these steps systematically to diagnose and resolve the blinking dashes issue:
1. Check and Replace Batteries
- Power Down: Turn off your Mitutoyo caliper.
- Battery Inspection: Open the battery compartment and carefully inspect the batteries. Look for corrosion on the terminals or any physical damage to the batteries themselves.
- Replace Batteries: Replace the batteries with fresh ones of the correct type and voltage, ensuring proper polarity (+ and -).
- Power Up: Turn the caliper back on and check if the blinking dashes have disappeared.
2. Clean Battery Contacts
- Clean Terminals: Use a clean, dry cloth or a cotton swab to gently clean the battery terminals and the contacts in the battery compartment. Remove any corrosion or debris.
- Reconnect Batteries: Reinsert the batteries, making sure they are securely seated and making good contact with the terminals.
- Power Up: Turn on your caliper and see if the blinking dashes are resolved.
3. Reset the Caliper (If Applicable)
Some Mitutoyo caliper models have a reset function. Consult your caliper's instruction manual for the specific procedure. This often involves holding down certain buttons for a few seconds.
4. Seek Professional Repair
If the blinking dashes persist after trying the above steps, it's best to seek professional repair from a qualified technician or send the caliper back to Mitutoyo for servicing. Attempting to repair the caliper yourself could void any warranty and potentially cause further damage.
Preventative Maintenance for Your Mitutoyo Caliper
Regular maintenance can significantly extend the life of your Mitutoyo caliper and reduce the likelihood of encountering issues like blinking dashes:
- Proper Storage: Store your caliper in a clean, dry, and protected environment to prevent damage and corrosion.
- Regular Cleaning: Periodically clean your caliper with a soft cloth and appropriate cleaning solution. Avoid harsh chemicals or abrasive materials.
- Calibration: Regularly calibrate your caliper according to the manufacturer's instructions to ensure accuracy.
- Avoid Dropping or Impact: Handle your caliper carefully to avoid damage from drops or impacts.
By following these troubleshooting steps and practicing preventative maintenance, you can keep your Mitutoyo caliper functioning accurately and efficiently for years to come. Remember, if you're unsure about any of the procedures, consulting your user manual or contacting Mitutoyo support is always the best course of action.
