Mitutoyo Caliper Error Code E--05 [2021] Jun 2026

Unlike generic "low battery" warnings or simple zero-setting errors, E--05 on a Mitutoyo caliper specifically indicates a This code appears most frequently on models featuring Absolute (ABS) linear encoder technology, such as the popular Absolute Digimatic series (e.g., 500-196-30). The "synchronous" aspect refers to the communication between the sensor head (the moving slider) and the scale (the etched glass or metal strip within the beam). When the caliper displays E--05, it means the internal electronic system has detected a loss of synchronization between these two components. In practical terms, the caliper cannot reliably determine the absolute position of the jaw, making all subsequent measurements potentially incorrect.

For Mitutoyo Absolute calipers, after reinserting the battery, you may need to press the button to reset the zero point. If your model lacks an Origin button, simply close the jaws fully and press the "ZERO/ABS" button. mitutoyo caliper error code e--05

Error code on a Mitutoyo Digimatic caliper indicates a CPU/ROM (Read-Only Memory) malfunction . Unlike simple scale contamination errors (E--01 or E--02), E--05 signifies that the internal processing unit has failed a self-diagnostic check, typically due to a corrupted internal program, a severe voltage drop, or a hardware component failure. Unlike generic "low battery" warnings or simple zero-setting
