PREPARATION
SCDI- *** S
① Select a combination of Extension Rod and Washers as close as possible to the ID of the part to be measured.
※ Must be withing measuring range of attached Gauge.
※ For SCDI-8S、 12S、 20S the Extension Rod and Washer attach directly to the Measuring Head.
For SCDI-35S、 60S、 100S、 160S、 attach the Extension Rod and Washer using the Clamp Nut.
② Attach a measuring instrument such as a dial gauge ( sold separately ) to the Instrument Body.
OPERATION
※SSCDI Series Bore Gauge is a comparative gauge and requires a Reference Master such as a ring gauge to set
up for comparative measurements.
※Prepare a Reference Master appropriate for the dimensions of the part to be measured.
Please Observe
※Before use, make sure the components on the Measurement Head are all securely attached and not loose.
SETTING THE 0-POINT
①Prepare a Ring Gauge to use as a reference standard for setting
the zero-point. Insert the Measurement Head into the ring gauge.
②In the direction perpendicular to the Ring Gauge axis, position the
Bore Gauge to measure diameter ⓐ shown in the cross section
( Fig. 1 ) . This is the maximum distance, and the Gauge will show
the minimum reading. The Guide moves to automatically position
the Gauge Head at this diameter when inserted.
③In the cross section shown in Figure 2, parallel the Ring Gauge
axis though diameter ⓐ, position the Bore Gauge to minimize the
distance ⓑ. In this position the Gauge will read the maximum
value.
This position is determined by manually moving the gauge and
noting the position where the Pointer shows the maximum value.
( Fig. 3 )
④The reading obtained at step ③ is the zero-point. Set the Gauge
to zero and the zero point is now set. ( Fig. 4 )
MEASUREMENT
Insert the Measurement Head of the Bore Gauge into the
object to be measured. As in step ③ of "Setting the 0-
Point" above, pivot the gauge while checking the pointer to
determine the diameter ⓑ where the gauge will show the
maximum value to determine the measurement reading.
This measurement will be the difference in diameter between
the part and the reference Ring Gauge.
AFTER USE CARE, STORAGE
●
Clean outside surfaces regularly using a cloth to remove any
SCDI−160S dirt or contamination.
●
Use a cloth dampened with a cleaning solution if required for
100-160
excess dirt.
●

After use, place in a rust preventive bag or use a corrosion
inhibiting oil for protection.
●
7pcs.
Store in supplied case, protected from direct sunlight or
100・110・120
humid environments, and accessible only to authorized
130・140・150
personnel.
