 How to use Snap Caliper ( EG-1, EG-2 ) |
 |
| To measure thickness and diameter of balls : |
| (1) |
First, press down a knob to check whether a pointer shows 0. |
| (2) |
As shown in the drawing II , put an object for measurement between a contact point |
|
and anvil, and read a position of pointer on a dial plate. A division of scale is 0.1 mm, |
|
so read the values on the dial 1, 2, 3... as 1, 2, 3 mm... ( After one rotation, it shows 11, |
|
12, 13 mm... ) |
| (3) |
One rotation of a pointer shows 10 mm. Check whether it is first or second rotation by |
|
reading a spindle scale indication. |
|
( Example ):A pointer shows 6 at your measurement: |
|
1st rotation --> 6 mm, 2nd rotation --> 16mm |
|
 |
| To measure groove width and inner diameter : |
| (1) |
Press down a knob and have a contact point and anvil contacted fast, then rotate an |
|
outer frame of gauge so that a division of 3 on a dial plate meets a position of pointer. |
| (2) |
Pressing down a knob by your fingers, insert the tips of contact point and anvil into the |
|
inside of an object for measurement, and slowly release a knob, as shown in the |
|
drawing III |
|
( Notice ) :Measure an object at right angles to a groove. If you measure it diagonally, |
|
a value larger than the actual one will be indicated. |
|
 |
| To measure depth and step depth -( EG-2 only is available. ) |
| (1) |
Rotate an outer frame of gauge so that a pointer meets 0 on a dial plate, by putting |
|
a flat plate on the reference level of gauge. ( If there is no adequate plate, put your |
|
gauge upside down, and press the reference level of gauge on a flat table ). |
| (2) |
Press your gauge down to the measuring part of an object for measurement, as |
|
shown in the drawing IV |
|
