Mitutoyo Caliper Error Code E--05 [Reliable →]

For Mitutoyo Digimatic instruments, the ) error code typically indicates an overspeed error

Wrap the caliper in a cloth.
Use a hair dryer on low heat to warm the back of the slider (where the PCB sits) for 30 seconds.
While warm, gently squeeze the front and back of the slider together.
Cool and test. If this works, the internal elastomeric connector (zebra strip) was loose. The caliper will likely fail again soon and needs professional reseating.

Here is a quick guide to clearing the error and preventing it from returning: 1. Reset the Display mitutoyo caliper error code e--05

What Does Error Code E--05 Actually Mean?

Unlike common errors like "E--01" (scale contamination) or "E--02" (excessive speed), E--05 is a system-level hardware fault. According to Mitutoyo’s internal service manuals and field reports from experienced metrologists, E--05 indicates a failure in the capacitive linear encoder’s reference signal detection. For Mitutoyo Digimatic instruments, the ) error code

Fix:

Clean the scale and head:

Step 4: Reinsert the Battery

Place a fresh CR2032 battery in. Low voltage is a frequent accomplice to E--05. Even if your old battery reads 3V, try a new one. Wrap the caliper in a cloth

: The E-05 is specifically designed to trip if the slider moves faster than the electronic encoder can process (typically around 1.5 meters per second). Check for interference

: Coolant, oil, or dust on the scale surface disrupts the capacitive sensor's ability to read the graduation. Low Battery
