■ ASSEMBLY
①Loosen the Clamp Screw and insert the Digital
Indicator into the gauge body. Tighten the Clamp
Screw to secure.
※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.
② Select the combination of Sub Rod ( WCD-160
only ) Extension Rod and Washers for the
dimension you want to measure.
Remove the Rod Adj. Nut put on the desired Sub Rod, Rod, and Washers,
and secure with the Extension Rod Mounting Nut.
※Please select combination with fewest number of Washers.

■ MEASUREMENT
< > For accurate measurements, follow the procedure described below.
combined
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.

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 )
