1
●
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
7
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.
9 APPLICATIONS & FEATURES

MEASUREMENT
SCG- ***
①
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)
②
The Dial Gauge will indicate the maximum
diameter of the chamfer. (Fig. 2)
ZERO ADJUSTMENT
PLEASE OBSERVE
Setting Zero Point on Flat Reference Surface
①
A smooth, hard surface is required as Reference
Surface.
or

②
Place the Measurement Head perpendicular to
if not followed.
the Flat Reference Surface and slowly push in
until there is no gap. (Fig 3)
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.
Setting Zero Point Using a Reference Standard
① Prepare an ID Chamfer Reference Standard for use.
② 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.
③ 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.
AFTER USE CARE, STORAGE
●
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.
