: Use a clean, soft cloth to wipe the entire length of the scale surface. If it is heavily soiled with coolant or oil, a small amount of isopropyl alcohol or a very light application of low-viscosity oil (like CRC 3-36) can help maintain the surface.
On the slider’s back, locate the thin flexible circuit entering the housing. Look for creases, cuts, or corrosion at the solder points. mitutoyo caliper error code e--05
Replace the old battery with a high-quality (such as Energizer, Duracell, or Maxell).
Even if you own an IP67-rated coolant-proof Mitutoyo caliper, extreme exposure to pressurized coolant, deep submersion, or sudden temperature drops can cause internal condensation. Moisture directly on the internal circuit board will short out the sensor lines, leading to an immediate E--05 shutdown. Step-by-Step Troubleshooting and Solutions Disclaimer: This document is for informational purposes
If you have replaced the battery with a premium SR44 cell, thoroughly cleaned the beam, and held down the ORIGIN button, but the "E--05" code still will not clear, your caliper likely has internal damage. This usually points to:
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. If it is heavily soiled with coolant or

Occasionally, slide a clean piece of paper between the measuring jaws and close them lightly to pull away any hidden debris.
Insert a . Avoid using LR44 alkaline batteries; LR44 batteries suffer from rapid voltage drops that frequently trigger E--05 and erratic readings in Mitutoyo tools. Step 3: Deep Clean the Scale and Beam
