Mounting the Extensometer
2-7
Product Support:
The 25-way D type connector wired to the
extensometer cable incorporates the normal
retaining screws, and an additional
mechanical safety locking device. When
inserting the connector, push it firmly into
the mating plug receptacle and ensure that it
is positively retained by the screws or the
locking latch.
Procedure
1. Install the gauge length pin.
2. Orient the extensometer so that the
electrical cable exits from the upper side
of the extensometer.
3. While holding the extensometer in the
left hand, place it against the specimen
and hook a clamping spring or rubber
band to the far side of the upper knife
edge.
The fixed receptacle section of this locking
device is to be retrofitted on all machines
except table models. Special latching hooks
are included in all extensometer kits, to be
fitted under the mounting screws of the fixed
receptacle, for all servohydraulic and floor
mounted testing instruments.
