SAFETY PRECAUTIONS
PREPARATION - Mounting
Please Observe
Always follow the procedures specified below in order to prevent harm to yourself or others, and to
prevent damage to property.
Dial Indicator must be securely mounted such as on a comparator stand or magnetic base.
Please follow these guidelines.
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:
•Use in location contrary to the above may
cause poor accuracy, damage to the
product, or may result in accident or injury.
Do not shock Probe.
Do not drop or subject to shock, do not
place under heavy objects. Damage may
cause failure or poor accuracy.
■Content marked as follows indicates risk of injury or damage if not followed.
■These symbols mark content that must be observed.
CAUTION
WARNING Indicates risk of personal injury or property damage if not followed.
Denotes a prohibition – You MUST NOT do. Denotes a requirement – You MUST do.
Do not disassemble or modify.
●
It may damage Gauge and cause poor accuracy.
I f screws are removed, internal components
may come loose and become misaligned
causing product failure.
Do not shock Probe.
•Rapid motion, or lateral force may damage
Gauge and cause poor accuracy.
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.
Gauge must only be attached by Dovetail or Stem

For Best accuracy, use a reference master the same
height as the workpiece.
Attach Mounting Stem.
Loosen the Stem mounting bracket and slide the groove
onto the Dovetail in the desired position. Tighten the
Stem to secure. (Choose a stem with diameter to match
the Gauge Holder you plan to use.)
Confirm that the Probe and stem are secure
without any play.
If they are loose, tighten to secure.
Attach the Indicator Gauge to the Holder.
Please attach by the Stem only.
Confirm that the pointer moves freely.
Bring the Probe into contact with the workpiece,
and gently raise and lower the gauge while
checking the movement. Confirm that the pointer
returns to initial position when raised.
Make sure the Probe is parallel to the measured
surface, and perpendicular to the direction of
the measurement.
If probe is not positioned properly, the measurement
will be inaccurate and operation may be faulty.
HOW TO USE - Preparation
HOW TO USE - Comparison Measurements
Set Up Reference Part
Position the reference Part with the measured surface
parallel to the probe and perpendicular to the direction of
the measurement. Bring into contact with the probe, but
use care that the part does not bump the probe from the
side.
Set the Origin.
Adjust the gauge mount or rotate the Bezel to set
the Gauge to “0”.
Remove the Reference Part and Measure the
Workpiece
Remove the master with care not to jostle the gauge.
Replace with the workpiece and read the scale.
How to Use - (Parallelism, Flatness, Runout, etc.)
Position the probe on the workpiece.
Position the Part with the measured surface parallel to the probe and perpendicular to the direction of the
measurement. Bring into contact with the probe, but use care that the part does not bump the probe from the side.
Set the Origin.
Adjust the gauge mount or rotate the Bezel to set the Gauge to “0”.
Move the workpiece and read the scale.
Move the work slowly while reading the position of the pointer on the scale.

●
If origin position shifts during measurement.
Temperature changes during measurement can
cause 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.
•Make sure the Stem is not loose, and tighten if
necessary.
■Measurement is not stable, or measurement
accuracy is poor.
CALIBRATION
To maintain measurement accuracy, periodic calibration is recommended.
(For reference, we recommend a calibration interval of 3~4 months
when used in a factory.)
Outside Japan,
Please contact distributor or place of purchase to inquire about
calibrations services.

Remove any dust or dirt after use.
※ Do not lubricate.
•Wipe any contamination from Probe and moving surfaces
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 Probe tip.
• Measurement accuracy will be affected by worn Probe.
Regularly check for wear and replace Probe if worn.
Store in provided case in a cool, dark, and dry location.
Use only factory approved Probe. Using alternate
probe may cause error.
•Always perform calibration after replacing Probe.
Probe may be worn; a worn Probe will affect accuracy.
Periodically check for wear, and replace if wear is
affecting measurement accuracy.
