Mitutoyo is the gold standard in precision measuring tools. Their digital calipers, from the Absolute Digimatic series to the Solar and Coolant-Proof models, are trusted by engineers, machinists, and quality control professionals worldwide. However, even the most reliable instruments can display cryptic error messages that bring work to a halt.
Moisten the cloth slightly with a small amount of isopropyl alcohol (rubbing alcohol). Do not use heavy degreasers or WD-40, as these leave a residue.
Battery Issues: A weak or low-voltage battery often causes erratic behavior or error codes. Corrosion on battery contacts can also mimic this error by providing inconsistent power. Step-by-Step Troubleshooting mitutoyo caliper error code e--05
: On older units, repeated use can wear down the protective finish on the circuit board, leading to shorts. Steps to Fix Error E--05 E--05 error on a Digimatic caliper? - Practical Machinist
The E--05 error frequently appears when batteries drop below 1.35V (for an SR44) or 2.8V (for a CR2032). The caliper has enough power to light the LCD but not enough to generate the stable high-frequency oscillator needed for capacitive sensing. This produces erratic reference signals. Decoding the Mitutoyo Caliper Error Code E--05: Causes,
The simplest way to clear the code is to reset the electronic unit: Wipe the scale
Wipe the entire length of the scale with a clean, lint-free cloth dampened with denatured alcohol isopropyl alcohol Some users successfully use a light film of to displace moisture and improve sliding. Check the Battery Replace the battery with a brand-new cell (SR44
Note: Do not force the slider during these steps.
