Mitutoyo Caliper Error Code E05 Link Jun 2026

The internal micro-controller misses steps and flags a calculation mismatch.

: Close the jaws completely and hold the ORIGIN button for more than one second to re-establish the zero point. 2. Clean the Scale

Does your caliper show like a flashing "B" or a "P" alongside the error? E--05 error on a Digimatic caliper? - Practical Machinist

Remove the battery, short the terminals for 30 seconds, then—with the caliper fully closed—reinsert the battery. For height gages, you may need to open the unit and manually re-tension the encoder gear as described earlier.

Misconfigured baud rate, COM ports, or data bits in your Quality Control (QC) or SPC software.

An internal component has failed or broken, often due to a drop or physical shock.

Inspect the beam. If the caliper was dropped, the beam might be slightly bent. If the jaws drag or the carriage is misaligned, the sensor gap might be compromised. Unfortunately, this usually requires factory service.

A new battery doesn't eliminate other potential causes: scale contamination, a broken battery contact spring, moisture ingress, or a failed PCB. Follow the full troubleshooting sequence starting with scale cleaning. The internal micro-controller misses steps and flags a

If the E-05 error persists after thorough cleaning and battery replacement, the issue may be a failed component.

If you have replaced the battery, cleaned the unit, and the E05 error persists, it is possible that the internal PCB has been damaged or the encoder disk has cracked. At this point, it is recommended to , as amateur repairs on the encoder unit can ruin the calibration precision. Check out these resources for visualizing the fix: Mitutoyo E-05 error fixed! (Video)

Remove the back cover of the slider housing. Look for the small adjustment screws that control the spring-mounted collar (encoder preload). Tighten these slightly to ensure the sensor ring is properly against the scale. When to Seek Professional Repair

This article dives deep into the issue, providing a step-by-step diagnostic guide, repair solutions, and the technical explanation of why the "Link" (data output connection) is central to this problem.

Before taking anything apart, try a system reset.

Note: Mitutoyo does not maintain a single public page listing all error codes, but E05 is widely documented in their user manuals for ABS Digimatic calipers (e.g., Manual No. 99MBA041B).

A poor power connection is the most frequent cause of intermittent E-05 errors. Mitutoyo calipers rely on a stable voltage to maintain the Absolute encoder's position memory. When the electrical link is interrupted—even for milliseconds—the chip can lose its place, triggering E-05. Clean the Scale Does your caliper show like
