HOW TO USE - Preparation
①Confirm that the Contact Point and Rear Plate are tightly fastened.
If loose, tighten Contact Point and Rear Plate Screws.
②Attach to the Gauge Holder using the Stem or Rear Lug.
Mounting Gauge by other than Stem or Lug will cause inaccuracy and product damage.
③Confirm that Pointer and Revolution Counter movement is smooth.
Using fingertip, gently press on Contact Point to move the Spindle up and down. Motion of
Pointers should be smooth. If it is not smooth make sure Stem is not clamped too tight, and adjust.
Also make sure Pointer is stable at set position.
④Make sure Spindle axis is perpendicular
to measured surface.
If Spindle ( Contact Point ) is not at a right
angle to surface, Gauge will not operate
properly and measurement will be inaccurate.
Always keep the Spindle axis perpendicular.
※When used to check parallelism of Milling
Machine vise, use a Magnetic Base to
mount the Gauge perpendicular to surface,
and move it out of the way during operation
to prevent interference.
HOW TO USE - Comparison Measurements
①Set Up Reference Part.
Carefully lift Spindle with fingertip, and, taking
care not to hit Spindle from the side, insert the
Reference Part or Master under Contact Point.
②Set the Origin.
Adjust the gauge mount or rotate the Bezel to
set the Gauge to "0".
③Remove Reference, and begin
measurements.
Remove Reference or Master, careful not to
shock Spindle. Insert part to be measured and
read the measurement off the Scale.
※Setting the Limit Markers
Limit Markers can be moved to show
acceptance range for measurements.
HOW TO USE - Parallelism, Flatness, Runout, etc.
①Position Contact Point on surface.
Carefully lifting Spindle with fingertip, and taking care not to hit Spindle from the side, position the
surface to be measured under the Contact Point.
②Set the Origin.
Adjust the gauge mount, or rotate the Bezel to set the Gauge to "0".
③Read the scale as the measured part is moved.
Slowly move the part while monitoring the Pointer and reading the measurement.

■Content marked as follows indicates risk of injury or damage if not followed．
WARNING
■These symbols mark content that must be observed.
Denotes a prohibition – You MUST NOT do．
Read the manual and follow all instructions.
・Use of product other than as described in
the manual may cause accident.
Use only as indicator Gauge.
・Use for any purpose other than measuring
may damage or wear the instrument.
Improper use may also cause accident.
Use in an environment which meets the
following conditions:
●Temperature within range of 0~40° C、
humidity 30~70% ( non-condensing. )
●Location with minimal dust, oil, oil mist,
and protected from direct sunlight.
●Location protected from use by
children and unauthorized people.
・Use in location contrary to the above may
cause poor accuracy, damage to the
product, or may result in accident or injury.

PREPARATION - Mounting
⑭Rear Plate
Dial gauge must be securely mounted such as on a comparator stand or magnetic base.
with Lug
Please follow these guidelines.
Make sure Gauge holder is rigid.
・Holder must be sufficiently secure to prevent
deflection from the weight of the Gauge.
・Holder must be rigid enough to hold Gauge and
not to lift from measurement force.
・Holder support arm should be as short as possible
to prevent deflection.
※Deflection or lifting will cause measurement error
such as origin position error and inaccuracies in
measured reading.
Dial Gauge must only be attached by Stem or Rear Lug.
・Mounting of gauge by other than Stem or Lug will
cause inaccuracy and product damage.
During installation, do not over-tighten the Stem.
・Excessive force on the Stem may cause Spindle to bind.
TROUBLESHOOTING
■Origin position shifts during measurement.
・Temperature changes during measurement can cause repeatability error. Please try the following
solutions:
●Use in location with constant temperature.
●When taking measurements, periodically adjust zero point using a Master reference to correct
for temperature induced drift.
■Measurement is not stable, or measurement accuracy is poor.
・Contact Point may be worn.
Worn Contact Point will affect accuracy. Periodically check for wear, and replace if wear is
affecting measurement accuracy.

AFTER USE CARE, STORAGE
Remove any dust or dirt after use. ※Do not lubricate.
・Wipe any contamination from Spindle sliding surface using a dry cloth, or cloth moistened
with alcohol.
・To clean other surfaces, wipe with a soft dry cloth, or a cloth moistened with a mild cleaner.
Check for wear of Contact Point.
・Measurement accuracy will be affected by worn Contact Point. Regularly check for wear
and replace Contact Point if worn.
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 lateral force.)
・Keep away from moisture and direct sunlight, and secure from unauthorized personnel.
To maintain measurement accuracy, periodic
calibration is recommended.
Calibration interval necessary to maintain accuracy will vary
depending on frequency and conditions of use. Please follow
your companies guidelines and calibrate regularly.
Outside Japan,
Please contact distributor or place of purchase to inquire
about calibration services.
