How to use Snap Caliper ( EG-1, EG-2 )

Name of parts

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 thickness and diameter of balls
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 groove width and inner diameter
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
 To measure depth and step depth (EG-2 only is available.)
