BEFORE USE

HOW TO USE

Make the following preparations before taking measurements.
● Check for smooth movement of Measurement Lever,Pointer, and Rev. Counter.
Move the Spindle up and down with Measurement Leverand verify Pointer movement.
● Wipe off instrument to remove rust inhibitor and dirt.
Make sure gauge is clean for accurate measurements.
⑦ Meas. Lever

Gently move up and down

Absolute Measurement① Set the Zero Point
With the Contact Points closed, rotate the Bezel to set
the Pointer to zero.

TROUBLESHOOTING■Origin position shifts during measurement.
・Temperature changes during measurement cancause repeatability error. Please try the following
solutions:● Use in location with stable temperature.
● When taking measurements, periodically adjust
zero point using a master reference to correct for
temperature induced drift.
■Poor accuracy may cause unstable measurements.
・Measuring Surfaces may be worn.
If worn, measurement accuracy may be affected.
Check for wear regularly and replace Contact Points
as required.

AFTER USE CARE, STORAGE
Remove any dust or dirt after use.
※ Do not lubricate.
・Exterior surfaces may be cleaned by wipingwith a soft cloth, moistened with mild detergent.
Check for wear of Contact Points.
・Worn measuring surfaces will affect accuracy.
Regularly check for wear and replace ifrequired.
Store in provided case in a cool, dark, and dry location.
・ During storage, make sure there is no force
on the Spindle (such as pushed in, or lateralforce.)
・ Keep away from moisture and direct sunlight,
and secure from unauthorized personnel.
