| 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 |

| Major Specifications | | (1) | A division of scale | 0.1mm | | (2) | Measuring Range | for measurement of thickness | 0 ～ 20mm |
|
| for measurement of inner diameter | 3 ～ 23mm |
|
| for measurement of depth | 0 ～ 20mm | | (3) | Weight | EG-1 ; 97g | EG-2 ; 100g |
|
| Remarks |
| After your finising measurements of internal diameter and step depth, adjust a pointer so |
| as to meet 0 on a dial plate for thickness measurement. |
