INSERT
Shaft (Fig.1)(Fig.2)(Fig.3)(Fig.4)(Fig.5)(Fig.6)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 Guide will automatically position the Measurement
Head to diameter ⓐwhen inserted.
※WCDI-10D does not have a guide on the Measurement Head so please manually position at this maximum value.
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.
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.
