Dial Indicator / Comparator
DIAL INDICATOR
Thank you for purchasing the Niigata Seiki Dial Indicator.
Used with a Magnetic Base or Indicator Stand, this gauge will show the difference in height or position
relative to a zero point set at a reference position.
■
APPLICATIONS
● Tight places where plunger type Dial Gauge can not be used.
Use on milling machines and laths for centering, measure runout, parallelism,
●
flatness, etc.
Mount on height gauge for various measurements.
●
●
For safe and proper use of this product, please read this
instruction manual before use and follow the procedures
described. Please keep manual where it is accessible to
user for future reference.
●
Keep this manual with the instrument if transferred or
leased to a third party.

HOW TO USE - Preparation
①Attach 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. )
②Confirm that the Probe and stem are secure
without any play.
If they are loose, tighten to secure.
③Attach the Indicator Gauge to the Holder.
Please attach by the Stem only.
④Confirm 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.
⑤Make 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 - Comparison Measurements
①Set 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.
②Set the Origin.
Adjust the gauge mount or rotate the Bezel to set the
Gauge to "0".
③Remove the Reference Part and Measure the
Workpiece.
Remove the master with care not to shock the gauge.
Replace with the workpiece and read the scale.
HOW TO USE - Parallelism, Flatness, Runout, etc.
①Position 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.
②Set the Origin.
Adjust the gauge mount or rotate the Bezel to set the Gauge to "0".
③Move the workpiece and read the scale.
Move the workpiece slowly while reading the position of the pointer on the scale.

SAFETY PRECAUTIONS
Always follow the procedures specified below in order to prevent harm to yourself or others, and to
prevent damage to property.
■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.
Handle With Care.
・Do not drop or subject to shock, do not place
under heavy objects. Damage may cause
failure or poor accuracy.
PREPARATION - Mounting
Dial Indicator must be securely mounted such as on a comparator stand or magnetic base.
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 Dovetail or Stem.
・Mounting of gauge by other than Stem or Dovetail will cause
inaccuracy and product damage.
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.
⑧ Dovetail
・Make sure the Stem is not loose, and tighten if necessary.
groove
■Measurement is not stable, or measurement accuracy is poor.
・Probe may be worn; a worn Probe 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.
・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.
・During storage, make sure there is no force on the Probe ( such
as pushed in, or lateral force. )
・Keep away from moisture and direct sunlight, and secure from
unauthorized personnel.
Use only factory approved Probe. Using alternate probe
may cause error.
・Always perform calibration after replacing Probe.
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.
