Tips
• The display of this product automatically turns off if not used for 20 minutes or more. To display again, either rotate
the thimble or press the [ZERO/ABS] key.
• If the [PRESET] key is accidentally pressed during measurement, press the [ZERO/ABS] key to return to the former
state. If this does not enable the product to recover, perform "5. PRESET Value (Reference Point) Setting" once
more.
• Do not handle gages (gauge blocks, setting standards for outside micrometers, etc.) with your bare hands. Use
precision work gloves such as cotton gloves.
6. Measurement Method
• Be sure to perform reference point setting before measurement.
• Bring the measurement surface of the spindle slowly into contact with the workpiece. Moving too quickly
could deform the workpiece and affect measurement results.
Gradually and lightly bring the measurement surfaces into contact with the workpiece in the same orientation and
conditions as for reference point setting, apply the appropriate measuring force, and then read the display value
(see "3. Precautions for Use
■
Measuring Force").
