INSTRUCTION MANUAL
Thank you for purchasing the S-LINE CHAMFER GAUGE.
This precision instrument performs a simple yet highly accurate measurement of chamfer maximum diameter.
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.
For inquiries about this product, please contact dealer or Niigata Seiki at the address listed on the following page.
Model SCG-4090 shownAlways follow the procedures specified below in order to
prevent harm to yourself or others, and to prevent damage to
property.
If Gauge does not operate properly, or if you have any
questions, please contact distributor or place of purchase.
Please note, manufacturer is unable to respond to inquires or
provide service directly. Please contact distributor or place of
purchase.
Clean outside surfaces regularly using a cloth to remove any dirt or contamination.
After use, place in a rust preventive bag or use a corrosion inhibiting oil for protection.
If surfaces are dirty, wipe with a clean cloth moistened with a cleaner such as Niigata Seiki STC-500.
Store in location protected from direct sunlight and humidity, and accessible only to authorized personnel.
A smooth, hard surface is required as Reference
Surface.
Place the Measurement Head perpendicular to
the Flat Reference Surface and slowly push in
until there is no gap. (Fig 3)
The number printed on the side of the Dedicated
Gauge is the Reference Value used for zero
adjustment. (Fig. 4)
Adjust the reading to match the Reference Value
by rotating the Bezel of the Dedicated Gauge.
(Fig. 5)
When the Gauge Reading matches the Reference
Value, the zero adjustment is complete.
Repeat the measurement several times to
confirm that the value is stable.
Hold the Measurement Head perpendicular
to the workpiece and slowly push in until
there is no gap between the workpiece
and the Measurement Head Reference
Surface. (Fig. 1)
The Dial Gauge will indicate the maximum
diameter of the chamfer. (Fig. 2)
Zero point is set at factory, but we recommend
periodic adjustment as required.
Prepare an ID Chamfer Reference Standard for use.
Hold the Measurement Head perpendicular to the Reference Standard and slowly push in until
there is no gap between the Reference Standard and the Measurement Head Reference Surface.
Adjust the reading to match the Reference Standard by rotating the Bezel of the Dedicated Gauge.
(Fig. 5) When the Gauge Reading matches the Reference Standard, the Zero Adjustment is complete.
Repeat the measurement several times to confirm that the Value is stable.

Measurement Head and Measurement Taper are
hardened steel and sensitive to corrosion. Please
keep well protected with rust inhibitor when not in
use.
Only use with the dedicated Dial Gauge. Use of
any other gauge will cause reading error.
Do not remove Dial Gauge, or loosen the holding
screw. Loosening screw will cause reading
inaccuracy.
Use care when contacting Measuring Head to
workpiece and avoid impact; there is risk of
damage to Measurement Taper.
Instrument is designed for measuring the ID
chamfer max. diameter.
Use for any other purpose may cause accident or
injury.
The chamfer diameter (max diameter) for a
range of chamfer angles can be measured.
Dedicated Dial Gauge for direct reading of
measurement.
Meas. Taper
Indicates risk of or
