Once the battery is back in, hold the "Origin" button for more than one second to reset the zero point. 2. Clean the Measuring Scale
Mitutoyo digital calipers are widely regarded as the gold standard in precision measurement, known for their accuracy and durability. However, even the most robust tools can encounter errors. When your digital display suddenly shows , it signifies a serious disruption in the measurement process.
Here is a quick guide to clearing the error and preventing it from returning: 1. Reset the Display
Ensure the caliper still slides smoothly without binding. If it feels too stiff, back the screws off slightly. How to Prevent the E--05 Error Code mitutoyo caliper error code e--05
If pins are bent, you can very gently realign them using a pair of precision tweezers.
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
Often, clearing the error simply requires refreshing the microprocessor. Stop moving the slider jaws. Press the or ORIGIN switch on your front panel. Once the battery is back in, hold the
Even on "Coolant-Proof" models, microscopic debris—oil mist, graphite dust, aluminum chips, or dried coolant residue—can bridge the gap between the scale and the sensor. This creates a false capacitance reading, confusing the processor into thinking the reference signal is missing.
Reinsert the battery (or a brand-new one) and check the display. Step 2: Clean the Scale and Slider Cleaning is the most effective fix for this specific error. Open the caliper jaws completely.
: Moving the slider faster than the sensor's maximum response speed can trigger this code as it "loses track" of its position. However, even the most robust tools can encounter errors
To minimize downtime and protect your metrology investment, implement these preventative habits:
: A weak battery (SR44) can cause the internal processor to glitch, leading to the E--05 code.
Understanding and Fixing the Mitutoyo Caliper "E--05" Error Code
Wipe the entire length of the scale with a clean, lint-free cloth dampened with denatured alcohol isopropyl alcohol Some users successfully use a light film of to displace moisture and improve sliding. Check the Battery
