2.0 O PERATING P ROCEDURES
1. Before beginning a new measurement,
reset the Memory Pointer to the zero
position. (See section 2.1.)
To return the Memory Pointer to the
zero position, rotate the knurled knob
on the face of the instument counter-
clockwise until the pointer has been
reset. See figure at right.
2. Place the instrument on the material to
be tested. The durometer must be level,
and the sensing pin must be perpendicular
to the material to be tested.
Any angle other than perpendicular (90°)
mauy cause errors.
3. Holding the knurled, spring-loaded outer
shell between fingers, press downwards
until the lower edge of the shell meets
the red line marked on the housing. This
ensures that sufficient pressure is applied
as specified in the standard. It also
ensures that the same amount of
pressure is applied from measurment to
measurement, and when the durometer
is used by different operators.
4. Rock the unit back and forth. The peak
value shown by the Memory Pointer is
the measured value. Release pressure
on the outer shell and remove the
durometer from the test material.
