TROUBLESHOOTING
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.
■
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
※
To Use the Rear Plate with Lug,
unscrew the standard Flat Rear
Plate screws, replace, and use
screws to secure.

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.
HOW TO USE - Preparation
Dial gauge 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:
●
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.
Handle With Care.
・
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
Indicates risk of personal injury or property damage if not followed.
WARNING
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
Do not shock Spindle.
・
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.
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.
No Rapid
Motion
No Lateral
Force
CALIBRATION
1. Confirm that the Contact Point and Rear Cover are tightly fastened.
If loose, tighten Contact Point and Rear Plate Screws.
2. Attach to the Gauge Holder using the Stem or Rear Lug.
Mounting Gauge by other than Stem or Lug will cause inaccuracy and product damage.
3. Confirm 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.
4. Make 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
1. Set 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.
2. Set the Origin.
Adjust the gauge mount or rotate the Bezel to set the
Gauge to "0"
3. Remove 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.
1. Position 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.
2. Set the Origin.
Adjust the gauge mount, or rotate the Bezel to set the Gauge to "0"
3. Read the scale as the measured part is moved.
Slowly move the part while monitoring the Pointer and reading the measurement.

In order to maintain instrument accuracy, it is recommended
that accuracy is confirmed through calibration on a periodic
basis.
Wear of measuring surfaces from repeated use may affect
accuracy and periodic accuracy checks should be performed.
We provide calibration services. Please contact
agent in country of purchase to make arrangements.
