Here is the content for a support or knowledge base article explaining the Mitutoyo Caliper Error Code E05, including its cause, solution, and a link to further resources.

Error Code E05 Meaning

E05 on a Mitutoyo Digimatic caliper indicates a "Reading Error" or "Counter Overflow" — typically meaning the display has reached a numerical limit, or there is a signal interference between the scale and the readhead.

Common causes:

• The slider moved too fast (exceeding the processor’s tracking speed)
• Low battery causing unstable signal
• Dirt or oil on the scale (stator/rotor interface)
• Electrostatic discharge or temporary logic lock-up
• Internal counter exceeded ±999.99 mm or ±39.999 inches (rare, but possible if zero is set then moved far)

When to Seek Professional Repair

If you have tried all the steps above and the error persists, you may have a hardware failure.

• Sensor Failure: The internal sensor head may be damaged (often caused by a drop or impact).
• Scale Damage: The scale strip itself may be scratched or dented. Once the physical scale is damaged, the caliper cannot hold accuracy and needs repair.
• Liquid Damage: If coolant entered the electronics, the main board may be shorted.

In this case, you cannot fix the caliper yourself. Contact Mitutoyo Technical Support or your local authorized service center for calibration and repair. mitutoyo caliper error code e05 link

When is the caliper truly faulty?

If E05 appears even when moving very slowly (e.g., 10 mm/sec or less), and cleaning + a new battery do not resolve it, the internal reader head or scale may be damaged. In this case, repair or replacement is needed.

Step 4: The Origin Reset (ABS System)

If the scale is clean and the battery is new, you may need to reset the origin.

1. Close the jaws gently.
2. Press and hold the ORIGIN (or Zero/Set) button for 3–5 seconds until the display flashes or resets to 0.00.
3. Open the jaws fully and close them again to check if the error persists.

2. The "Sleep" Wake-Up Glitch

Mitutoyo Absolute encoders remember position when off. However, static discharge during power-up can corrupt the initial link. Error Code E05 Meaning E05 on a Mitutoyo

• Fix: Remove the battery. Press the Origin button for 10 seconds to drain residual capacitance. Reinstall the battery. Set the Origin point (usually jaw closure + Origin button).
