On Mitutoyo Digimatic instruments, this code typically triggers when the electronic circuit cannot process the displacement signal correctly. While most common on micrometers, it appears on calipers when the reading head encounters a "dead spot" or interference on the scale. Primary Causes Contamination
The is intimidating when it first appears, but it is almost always a temporary, user-correctable condition. In the vast majority of cases, pulling the battery for 60 seconds and cleaning the beam will bring your precision tool back to life.
: 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
If basic cleaning and a new battery don't work, you may need to perform a more thorough cleaning of the internal sensor. mitutoyo caliper error code e--05
Let’s break that down.
One forum post suggested that the error might be caused by a faulty sensor or a problem with the caliper's internal mechanism. Another post recommended trying to reset the caliper by pressing a combination of buttons, but John had already tried that without success.

Keep your caliper in its fitted plastic case when not in use to protect it from dust and airborne oil mist.
| | Avoid That | | --- | --- | | Move the slider smoothly, like a violin bow. | Snapping or flicking the jaws open/closed. | | Store the caliper in its foam-lined case. | Leaving it on a magnetic chuck or VMC table. | | Replace the battery annually, even if it works. | Waiting for the "B" (low battery) indicator. | | Clean the beam gently with a dry cloth daily. | Using compressed air or solvent sprays. | | Press "Origin" after each battery change. | Slamming the jaw shut to zero it out. |
Let’s face reality. If you have performed the hard reset, replaced the battery, cleaned the scale meticulously, and moved at a snail’s pace, yet persists or appears randomly every few minutes, your caliper is likely suffering from a failed encoder ASIC (application-specific integrated circuit) or a cracked substrate. - Practical Machinist If basic cleaning and a
Press and hold the or ZERO/ABS button for 10 seconds to drain residual power. Reinsert the battery and close the cover.
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.
