High humidity or direct exposure to liquids can create a moisture bridge on the main scale. While many modern Mitutoyo calipers feature IP67 coolant-proof protection, older or standard models are highly sensitive to moisture. 3. Low or Fluctuating Battery Voltage
In most cases, no. When caused by a weak battery, contamination, or a temporary overspeed event, the error disappears once the underlying cause is fixed, and the caliper returns to its original calibrated state. However, if the error is due to a mechanical issue like a lost gear spring, the alignment may be slightly affected, and a full recalibration against a gauge block might be advisable.
Use a clean, dry, lint-free microfiber cloth to wipe down the entire length of the stainless steel beam.

The E--05 error on a Mitutoyo digital caliper signifies a .
To avoid future E--05 errors, users should adopt disciplined practices. First, always slide the caliper at a moderate, steady speed—never "flicking" or rapidly accelerating the slider. Second, keep the caliper clean and dry, storing it in its protective case away from coolant mist and chips. Third, replace the battery promptly when the low-battery indicator appears, and use high-quality cells. Finally, perform a quick "origin reset" each time the caliper is powered on, especially after battery changes. These habits not only prevent E--05 but also extend the instrument's life and maintain its certified accuracy. Perform a Hard Reset : On older units,
Even a microscopic film of oil, coolant, or dust can cause an E--05. Use a soft, dry, lint-free cloth (microfiber is best).
. This occurs when the sensor loses its position tracking, often caused by electrical noise, a weak battery, or physical contamination on the scale. Common Causes Contamination
Follow these steps in order to resolve the E--05 error code on your Mitutoyo caliper: Step 1: Perform a Hard Reset Sometimes the microprocessor just needs a fresh start. Remove the battery entirely from the caliper. Leave the battery out for 30 to 60 seconds.
