■REPAIRS AND SERVICE
● 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.
(Figure1)
(Figure2) (Fig.3)
① Prepare a Ring Gauge to use as a reference standard
for setting the zero-point. Insert the Measurement Head
into the ring gauge.
②In the direction perpendicular to the Ring Gauge axis,
position the Bore Gauge to measure diameter ⓐ shown in
the cross section (Figure 1). This is the maximum distance,
and the Dial Gauge will show the minimum reading. The
The Guide moves to automatically position the Gauge
Head at this diameter when inserted.
③In the cross section shown in Figure 2, parallel the Ring
Gauge axis though diameter ⓐ, position the Bore Gauge to
minimize the distance ⓑ. In this position the Dial Gauge
will read the maximum value.
This position is determined by manually moving the gauge
and noting the position where the Pointer shows the
maximum value. (Figure 3)
④The reading obtained at step ③ is the zero-point. Rotate
the bezel of the gauge until the Pointer is at the zero point
of the Gauge Face. (Figure 4)
※Before use, please make sure the Measurement Head is
not loose on the Handle. Tighten as necessary.
Insert the Measurement Head of the Bore Gauge into the
object to be measured. As in step ③ of “Setting the 0-
Point” 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.
This measurement will be the difference in diameter
between the part, and the reference Ring Gauge.
