Never spray WD-40 directly into the caliper body. WD-40 can dissolve lubricants and leave a residue that attracts dirt, potentially triggering E-05 errors.

Ensure your workstation is grounded; static spikes through the output port can trigger E05.

: Standard alkaline batteries drop voltage linearly and trigger sensor errors.

Use a soft cloth lightly dampened with . Wipe the scale surface from end to end. After cleaning, apply a thin film of low-viscosity oil (CRC 3-36 or light machine oil) to repel moisture and contaminants.

Error code on a Mitutoyo digital caliper indicates a scale contamination or signal error . This happens when the sensor cannot read the physical scale due to debris or electrical interference. 🛠️ Immediate Fixes
