Tips
• Changing the contact point may cause changes in external dimensions and measurement
force, or restrictions on measurement directions.
• Errors due to the contact point (perpendicularity of at contact point, center runout of roller con
-
tact point, etc.) are added to the measurement accuracy.
• Various contact points are available as options. Refer to the Mitutoyo MEASURING INSTRU

Move the plunger to the point to be set as the reference point, and then press the [ORIGIN] key
for 1 second or more.
⇨
The indicated value becomes zero and the reference point (ORIGIN) is set.
Tips
• Place the contact point on the workpiece several times to verify that the measured value is stable.
• This product does not guarantee stable repeatability within 0.2 mm from the bottom dead
center (when the plunger is completely extended). When performing reference point setting, be
sure to lift the plunger at least 0.2 mm above the bottom dead center.
0.2 mm
• A rubber damper is attached to this product to soften the plunger impact. Although the indicated
value may not be stable at the bottom dead center due to the elasticity of the damper, this is
not a malfunction.
