The sensitive, high-precision electronics cannot withstand severe shocks.
Close the jaws completely and ensure no light gaps are visible. Reinsert the battery.
Contaminants block the electrostatic field read by the slider sensor. Re Setting Mitutoyo Digimatic Calipers mitutoyo caliper error code e05 link
Open calipers slightly, use lint-free cloth with absolute ethanol (not acetone). Wipe the capacitive scale strip gently.
As the silver oxide battery (SR44 or LR44) approaches end-of-life, its output voltage drops. Insufficient voltage prevents the chip from reliably reading the capacitive encoder, leading to erratic errors—including E-05. Contaminants block the electrostatic field read by the
The error code on Mitutoyo Digimatic calipers typically indicates an overspeed error or a counter overrun , which can occur if the sensor loses track of its position or experiences an electrical glitch. This is often caused by physical interference, such as moisture, debris, or a sudden shock. Common Causes & Solutions
Clean the caliper jaws using a crisp piece of paper clenched tightly between them to remove debris. As the silver oxide battery (SR44 or LR44)
The on a Mitutoyo digital caliper typically indicates a communication or signal error , often caused by a poor connection or interference between the scale and the slider . Common Causes of E05
| E-05 Symptom | Likely Cause | Solution | | :--- | :--- | :--- | | Intermittent error; works when battery pressed | Weak battery contact | Replace battery; add shim or spring to contact | | Error appears when sliding quickly | Overspeed or weak battery | Move slower; replace battery | | Error present even when stationary | Scale contamination | Clean scale surface with alcohol; apply light oil | | Error after coolant exposure | Coolant ingress | Disassemble, clean with isopropyl alcohol, dry thoroughly | | Error on height gage when moved | Lost preload on encoder gear | Open unit, re-tension encoder gear against rack | | Error persists after cleaning and new battery | Failed PCB or scale | Contact Mitutoyo for repair |
Understanding the root causes helps target troubleshooting efforts.
