Keep instrument away from direct sunlight and
high temperatures such as in a car, near a stove
or heat source.
After use, remove dust and cutting chips and
apply rust preventative oil to components
including Extension Rods, and Extension
Washers. When not in use store in original case.
This product is for measuring inside diameter; use
only as directed. Improper use may cause
accident or injury.
Avoid using in locations with high electric fields,
such as near fluorescent lights or switching power
supplies, as it may cause erroneous reading to
display on LCD.
①Remove the protective cover by
unscrewing the two screws which hold the
cover in place.
※To reattach the protective cover, please refer to
the section: “Attaching the Protective Cover”
②Loosen the Clamp Screw and insert the
Digital Indicator into the gauge body.
Tighten Clamp Screw to secure.
※After attaching to body, press the
[
ZERO/ON
]
Button to turn on power. Check
for proper operation by pressing on the
Probe Tip. If the LCD display reading does
not change, readjust the insertion depth of
the indicator.
③Choose combination of Rod and Washer (CDI-18D only) applicable
for desired measurement range.
When using the Protective Cover, please attach using
the following procedure.
①Loosen the Clamp Screw and remove Clamp and
Spacer from shaft. (Figure: 1
)
②Without removing the Rod or Washers, follow the

■MEASUREMENT
For accurate measurements, please follow the procedure below.
①In cross section perpendicular to the axis of the bore, position the gauge along diameter ⓐ. (Figure: 1
)
This is the maximum distance, and at this point the Indicator will read the maximum value.
The Guide will automatically position the Measurement Head along diameter ⓐ.
※ CDI-10D Does not have a guide, manually position the probe for maximum reading in this direction.
②In cross section parallel to the axis of the bore through diameter ⓐ, position the indicator to minimize the distance ⓑ. (Figure: 2
)
In this position the Indicator will read the minimum value. This position must be manually achieved by pivoting the gauge and noting
the point where the Indicator shows the minimum value. (Figure: 3
)
①Before use, please make sure the Measurement Head components are securely tightened. Tighten as necessary.
②Clean the gauge head and the ID of a Ring Gauge Standard using parts cleaner or cleaning solution.
③Press the [ZERO/ON] Button to turn on power.※Power is turned off with a long press to the [ZERO/ON] Button.
■OPERATION
(
Figure: 1
) (
Figure: 3
)(
Figure: 2
)
①Turn on power. If the “ ”, “ ” symbols are displayed on the LCD, press the [MIN] Button to turn off.
②Make the “SET” value of the Bore Gauge match the ID of the Ring Gauge Standard. Press and hold the [ABS/SET] Button until
“SET” blinks on the display.
③Continue holding the [ABS/SET] Button and the display character to the left will blink. Use a short press of the [ABS/SET] Button to
change the value, and a long press to change the character being modified.
Repeat this process to enter the dimension of the Ring Gauge Standard on the LCD display. (Figure: 4
)
④When the value is entered, the flashing position will return to “SET”.
A short press of the [ABS/SET] Button to turn off the flashing.
⑤Insert the Measurement Head into the Ring Gauge Standard and
press the [MIN] Button to put the Indicator into minimum-mode. Slowly
pivot the gauge (Figure: 3) to display the minimum value.
⑥Remove the gauge from the Ring Gauge and press the [CAL] Button
until “OK” is momentarily displayed.
Preparation for measurement is now complete.
⑦Put the gauge into the workpiece to be measured, and pivot the gauge
slowly. (Figure: 3) The LCD will display the measured value. (Figure: 5
)
※Press the [ON/ZERO] Button momentarily to reset display in
preparation to measure the next workpiece.
ABSOLUTE MODE (ABS
)
※Displays absolute measurement of workpiece.
①Turn on power. If “ ”, or “ ” symbols are displayed on the LCD,
press the [MIN] Button to turn off. If “ABS” is displayed press the [ABS]
Button to turn off.
②Insert the measuring head into the Ring Gauge Standard and press
[
MIN] Button to put the Indicator into minimum-mode. Slowly pivot the
gauge (Figure: 3) to display the minimum value.
③Remove the gauge from the Ring Gauge and press the [CAL] Button
until “OK” is momentarily displayed.
Preparation for measurement is now complete.
④Put the gauge into the workpiece to be measured, and pivot the gauge
slowly. (Figure: 3) The LCD will display the difference between the
measured workpiece and the reference standard. (Figure: 6)
※Press the [ON/ZERO] Button momentarily to reset display in
preparation to measure the next workpiece.
※Display dif ference between workpiece and
reference standard.
