Figure 11 Pressure arm in operating position, over a powder press
CAUTION
The pressure arm must NOT be used without a volatiles cover or powder
press, as this will result in damage to the top plate.
When using a flat top plate and a solid sample, the surface of the
sample must be flat. You must not try to correct for uneven surfaces by
applying extra force as you may damage the crystal. Samples with
uneven surfaces should be ground to a powder and analyzed using a
trough top plate.

Screw down the pressure pin to apply force to the sample.
CAUTION
Excessive force can crack and permanently damage the crystal in the top
plate or damage the pressure arm. Be careful not to apply too much
force.
