INSTRUCTION MANUAL
Thank you for purchasing the S-LINE BORE GAUGE.
This product is a two-point mechanical instrument for measuring the ID of bores and holes relative to a reference
standard. Instrument can be used with a Dial Gauge, Digital Indicator Gauge, Electronic Sensor, etc.
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.
PART ID SAFETY
Please Observe
Always follow the procedures specified below in order to prevent
harm to yourself or others, and to prevent damage to property.
Indicates risk of personal injury or
property damage if not followed.
PREPARATION
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.
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.
Before use, make sure the components on the Measurement Head are all securely attached and not loose.
Prepare a Ring Gauge to use as a reference standard for setting
the zero-point. Insert the Measurement Head into the ring gauge.
In 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.
In 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)
The reading obtained at step is the zero-point. Set the Gauge
to zero and the zero point is now set. (Fig. 4)
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.
REPAIRS AND SERVICE
Clean outside surfaces regularly using a cloth to remove any
dirt or contamination.
Use a cloth dampened with a cleaning solution if required for
excess dirt.
After use, place in a rust preventive bag or use a corrosion
inhibiting oil for protection.
Store in supplied case, protected from direct sunlight or
humid environments, and accessible only to authorized
personnel.
AFTER USE CARE, STORAGE
SETTING THE 0-POINT
Insert the Measurement Head of the Bore Gauge into the
object to be measured. As in step 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.
