●This is a precision instrument, handle with care.
●Do not disassemble or modify.
●Keep instrument away from water and oil.
●Use only with supplied Probe Tips and Probe Needle.
●Keep instrument away from direct sunlight and high temperatures such as
in a car, or near a stove or heat source.
●After use, remove any dirt or cutting chips and apply rust preventative oil
to Probe Tip and Probe Needle. When not in use store in supplied storage
case.
●This product is for measuring inside diameter; use only as directed.
Improper use may cause accident or injury.
●Avoid using in high electric fields, such as near fluorescent lights or
switching power supplies. Electrical interference may cause incorrect
readings.
Pull out the case
from the two side
edges to remove.

■MEASUREMENT
①Loosen the Clamp Screw and insert the Digital
Indicator into the gauge body. Tighten the
Clamp Screw to secure. (Figure A)
②Insert the Probe Needle into the Probe Tip and
screw onto the end of the Handle. Tighten as
shown using the Spanner to secure.
(Figure B,C)
※Select Probe Tip to match the desired
measurement range.
※After attaching, press the [ZERO/ON]Button on
the Digital Indicator to turn on power. Confirm
that the displayed reading changes by gently
squeezing the measurement head.
If necessary, adjust the depth that the Digital
Indicator is inserted into the gauge body.
For accurate measurements, follow the procedure described below.
①In cross section perpendicular to the axis of the bore, as shown in Figure 1, position the gauge along diameter ⓐ. This is the
maximum distance, and at this point the Indicator will read the maximum value. The Measurement Head will automatically move to
diameter ⓐwhen inserted.
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 determined by pivoting the Gauge as
shown in Figure 3 while watching the Indicator to find the minimum value.
(Fig. 1)(Fig. 2)(Fig. 3)(Fig. 4)(Fig. 5)(Fig. 6)Example
①Press and hold the [ZERO/ON]Button to turn
power OFF.
②Press and hold [ABS/SET]and [ZERO/ON]
Buttons at the same time.
③When「-----」is displayed, ❶release the [ZERO/ON]
Button, ❷then release the [ABS/SET]Button in
that sequence.
④The Auto Off Delay time will be displayed. Press
[ABS/SET]to change.
※Each press of the [ABS/SET]Button will change the
delay by 1/2 hr. (30 min.)from 0 to 6 hr.
⑤Press [ZERO/ON]when done and display will return
to the measurement screen.
※
Once set, the delay time is saved even when power is
OFF.
①Before use, please make sure the Measurement Head components are not loose and tighten if necessary.
②Clean the Measurement Head and the ID of a Ring Gauge Standard using parts cleaner or cleaning solution.
③Press the [ZERO/ON]Button to turn on power. ※A long press to the [ZERO/ON]Button will turn power off.
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/SET]Button to turn off.
②Insert the Measurement 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 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 calibration standard. (Figure 6)
※Press the [ON/ZERO]Button momentarily to reset display in preparation
to measure the next workpiece.
①Turn on power. If the “”or “”symbols are displayed on the LCD, press the [MIN]Button to turn off.
②Adjust the “SET”value of the Bore Gauge to 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 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.
