Code E--05 - Mitutoyo Caliper Error

Slide the jaw smoothly. Avoid forcefully snapping the caliper open or closed.

If you've completed all the steps above and the error persists, the issue may be electronic or physical damage, including:

To maximize the lifespan of your precision tool and prevent the error from returning, implement these daily best practices:

In many cases, the caliper has simply "lost its place" electronically. You can force the caliper to re-find its origin manually. mitutoyo caliper error code e--05

Leave the caliper in a warm, dry environment (like an airing cupboard or under a desk lamp—never a microwave or oven) for 24 hours to let any internal condensation evaporate. How to Prevent the E--05 Error

What of Mitutoyo caliper do you have (e.g., CD-6"ASX, 500-196-30)?

Oil, coolant, dust, metal shavings, or moisture trapped between the main beam and the slider sensor.

Once the battery is back in, hold the "Origin" button for more than one second to reset the zero point. 2. Clean the Measuring Scale

Dealing with a can be frustrating, especially when you are in the middle of a precise job. This specific code generally points to a signal or communication failure within the measuring system, often triggered by environmental factors or internal hardware shifts. You can force the caliper to re-find its origin manually

Ensure the measuring faces and the main beam are completely dry and free of debris.

Reinsert the battery (ensure it is fresh) and replace the cover. Slide the slider across the beam to see if the code clears. Step 2: Inspect and Clean the Data Port

: If cleaning the exterior doesn't work, there may be debris inside the reader head.

If your Mitutoyo digital caliper suddenly stops showing measurements and instead flashes (or sometimes reads "Err 05" ), your tool has experienced a specific technical glitch.

Corrosion on the battery terminals or a poor connection between the batteries and the caliper can prevent the device from receiving the required power, triggering the E-05 error.
