High Load Mechanism - Agilent Technologies Nano Indenter G200 User Manual

Instrument Reference 3
The indenter head is the heart of the Nano Indenter G200. All of the
other subsystems can be considered support systems for the indenter
head. While the body of the indenter head is enclosed within the gantry,
the indenter tip is exposed during operation of the instrument or when
no power is supplied to the indenter's loading system (but only if the
locking pins are inserted).
While operation of the indenter is achieved entirely through the
NanoSuite software interface, there are some occasions when you will
work directly with the indenter head itself, most notably when you
change the tip.
When working directly with the indenter head, you should exercise
caution. Any time that you are working near or with the diamond tip,
you should be careful not to accidentally strike or move the indenter
because it is possible to damage the indentation system. Also, you
should avoid applying lateral forces to the indenter shaft because this is
the most likely way to damage the displacement-sensing system.
If you suspect that the indenter head has been damaged or is not
functioning correctly, contact your Agilent service representative.

High Load Mechanism

The High Load Mechanism is an option to allow application of
additional force, up to 10 N or 1 kg, to the test sample.
The high load mechanism is shown in Figure 3- 9 (Gantry Assembly lid
removed). As the stepper motor turns, it creates a torque around the
torsion bar. This force is transferred to the cantilever, which applies the
additional force to the indenter column needed to carry out high load
tests.
