Error Code E--05 =link=: Mitutoyo Caliper

from a drop that permanently altered the gap between the sensor and the scale.

: If the reading unit is physically damaged, the entire display assembly can be replaced using a small Phillips screwdriver, though this is often costly. E--05 error on a Digimatic caliper? - Practical Machinist

: Press the ON/ZERO or ORIGIN button once the scale is clean to see if the error clears. mitutoyo caliper error code e--05

At this stage, you will need to send the tool to an authorized Mitutoyo repair and calibration facility. Depending on the age and model of your caliper, they can replace the internal sensor block. However, if the tool is an older model, purchasing a new Mitutoyo absolute digital caliper may prove more cost-effective than professional factory repair.

Move the slider back and forth over the paper gently. The dry, slightly abrasive texture of the paper will grab trapped lint, dust, and oils out from under the sensor head. How to Prevent the E--05 Error from a drop that permanently altered the gap

By locking up and showing , Mitutoyo forces you to reset the tool, ensuring you never trust a reading that the electronics know might be wrong.

A: No. Calibration verifies accuracy. E--05 means the caliper cannot find its position. You must clear the error before you can calibrate or use the tool. - Practical Machinist : Press the ON/ZERO or

Unlike common errors like "E--01" (scale contamination) or "E--02" (excessive speed), . 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 .

This is a classic symptom of a damaged or contaminated scale beam, or a worn read head. If the caliper works well at one end of its range but consistently errors in the same specific zone (e.g., always between 20mm and 40mm), it indicates a localized problem. Visually inspect the scale beam in the affected area for:

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.

Before inserting the new battery, wipe it clean with a dry cloth to remove oils from your fingers. 4. Adjust the Slider Gibs (Advanced)
