Install a brand-new, high-quality (such as Energizer, Duracell, or Maxell). Avoid cheap LR44 alkaline batteries , as they drop voltage quickly and frequently trigger E--05 errors.
Note: Avoid LR44 alkaline batteries. While they physically fit, their voltage drops off rapidly as they discharge, which frequently triggers E--05 and flashing screen warnings.
: After reinserting the battery, fully close the jaws and press and hold the ORIGIN button for more than one second to re-establish the zero point. Advanced Solutions Mitutoyo E-05 error fixed!
Mitutoyo's documents indicate that "E--05" can appear when the slider is moved too quickly for the internal processor to keep up. This is a protective function and not an actual malfunction. The error should disappear once the slider is stopped. mitutoyo caliper error code e--05
Move the slider back and forth and wipe down the newly exposed areas of the scale. Let it air dry for a minute before turning it back on. Step 3: Check and Replace the Battery
Mitutoyo’s error code system distinguishes E--05 from E--01 (zero-set error) or E--02 (excessive speed error). E--05 strictly relates to between the capacitive absolute scale and the counter IC.
: Remove the battery and short the battery contacts with a small metal tool for roughly 30 seconds to drain residual capacitance and reset the internal processor. : Close the jaws completely and press and hold the button for more than one second to reset the zero point. 2. Scale Cleaning If the error occurs at specific points along the beam: Wipe the Scale While they physically fit, their voltage drops off
If you have thoroughly cleaned the scale, replaced the battery with a premium SR44, reset the origin, and the E--05 code still won't disappear, the internal electronics or the printed circuit board (PCB) may be permanently damaged.
On Mitutoyo Digimatic instruments, the code is often interpreted as an overspeed error or missing scan data .
At this stage, the caliper must be sent to an authorized Mitutoyo service center or a certified metrology lab for component repair or replacement. Best Practices to Prevent Future Errors Mitutoyo's documents indicate that "E--05" can appear when
While many E--05 errors can be resolved at home, certain situations warrant professional intervention:
When this code appears, the caliper will lock all functions (zero-setting, data output, mode switching). It is not a user-recoverable error in most cases.
If cleaning doesn't work, the battery is the next likely suspect. Slide open the battery compartment cap.
Low voltage can cause the processor to "trip" and throw error codes. Check for a flashing "B" or low battery indicator.
: On older units, the protective coating on the beam may wear down, exposing copper and causing intermittent electrical shorts. Troubleshooting and Solutions 1. Basic Reset and Battery Replacement
