MEASUREMENT
①Prepare a ring gauge to use as a reference standard for
setting the zero-point. Insert the Measurement Head
into the ring gauge.
②In cross section perpendicular to the axis of the ring
gauge, position the gauge along diameter ⓐ(Figure: 1).
This is the maximum distance, and at this point the Dial
Indicator will read the minimum value. The Gauge Head
will automatically sit in this position when inserted.
③In cross section parallel to the axis of the ring gauge
through diameter ⓐ, position the indicator to minimize
the distance ⓑ(Figure: 2). In this position the Dial
Indicator will read the maximum value. This position
must be manually achieved by moving the indicator and
noting the position where the Pointer shows the
maximum value. (Figure: 3)
④The reading obtained at step ③is the zero-point.
Rotate the bezel of the gauge until the Pointer is at the
zero point of the Indicator Face. (Figure: 4)
ZERO POINT ADJUSTMENT
※Before use, please make sure the Measurement Head is
secure. Tighten as necessary.
To use the Protective Cover, please attach using the following procedure.
①Loosen the Clamp Screw and remove Clamp and Spacer from shaft. (Figure: 5)
②Follow the “Assembly”procedure to mount the Indicator and secure with the Clamp.
③Mount the Protective Cover to the Indicator and attach with the 2 mounting screws.
(Figure: 6)
●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.
Insert the Measurement Head of the Bore Gauge into the
object to be measured. As in step ③of “Zero-Point
Adjustment”above, pivot the gauge while checking the
pointer to determine the diameter ⓑwhere the indicator
will show the maximum value to determine the
measurement reading.
