Mitutoyo Absolute Digimatic Caliper Error Code: E--05 Severity: High (Device Non-Functional)
Loosen these screws slightly, then retighten them. This allows the spring to push the encoder disk back against the pickup sensor.
Error on a Mitutoyo digital caliper is overwhelmingly a power or contamination issue that can be resolved with a new battery, a full capacitor discharge, and a thorough cleaning. If these steps fail, consider mechanical issues like lost gear tension or electronic problems like a worn PCB. For persistent errors, professional repair is the safest and most reliable path. With proper maintenance and timely troubleshooting, a Mitutoyo caliper can provide a lifetime of accurate service.
Inspect the scale sticker on the beam. If a sharp metal chip got caught under the slider and scratched through the protective coating of the internal scale patterns, the caliper is permanently damaged and the beam must be replaced. mitutoyo caliper error code e--05
To help narrow down the exact issue with your tool, could you tell me: The of your Mitutoyo caliper?
Remove the screws on the back of the sliding unit.
For older gear-driven models, if the cleaning doesn't resolve the issue: If these steps fail, consider mechanical issues like
: Use a high-quality silver oxide SR44 cell. Avoid alkaline equivalents, as they may have insufficient voltage stability for precision electronics.
A dying battery may supply enough power to turn the LCD screen on, but not enough voltage to power the encoder sensor properly.
This is the second most common cause. The capacitive sensor in a digital caliper relies on a clean scale surface to function. Even a thin layer of oil, dirt, or grime can disrupt the sensor's ability to count accurately. The official Mitutoyo manual for some models states: "If E--05 is displayed, wipe the scale surface with a soft cloth". Inspect the scale sticker on the beam
The error code on Mitutoyo Digimatic instruments typically indicates an overspeed error or a signal failure where the electronic sensor cannot properly read the scale . This often happens when the slider is moved too fast, if there is physical interference (like moisture or dirt) on the scale, or if the internal encoder has shifted .

To resolve the E-05 error on your Mitutoyo caliper, follow these troubleshooting steps:
However, while rapid movement is the most common cause, it is not the only cause. In some contexts, E--05 can also appear due to:
