•
Protect the extensometer from
mechanical shocks. Do not allow it to
drop and do not allow tools and other
equipment to strike it. Be careful about
placing the extensometer on a flat
surface where the electrical connector,
which is significantly heavier than the
extensometer, can pull the extensometer
onto the floor. Always use the magnetic
cable cleat.
•
Protect the extensometer from bending
stresses. Do not try to exercise the
flexural element beyond its mechanical
stops when handling or installing. When
operating the extensometer attached to a
specimen, ensure the maximum expected
strain for the sample under test does not
exceed the full scale of the extensometer
in use. Always use the limit control
feature of the Strain Conditioners to
prevent damage to the extensometer in
the event of specimen fracture or
inadvertent errors in control settings.
•
Always return the extensometer and its
accessories to the protective box when
not in actual use. This will prevent
inadvertent damage to the extensometer
and the loss of tiny accessories.
