a) The probe assembly (1) revolves freely. Probes may be screwed on by holding the
probe assembly between the thumb and forefingers with one hand and the probe in
the other. Alternatively, a small key is provided which may be inserted in the hole in
the probe assembly to prevent it from turning whilst loading or unloading a probe.
a) The working surface of the straining frame has a T shaped slot, which is used to
attach fixtures.
b) The loadcell has an M6 connection, which is used for attaching the top part of
fixtures (where appropriate)
c) Probes have an M3 connection, and are attached to the loadcell using any of the
three adapters supplied with the instrument.
d) At the front of the straining frame there are six LED's (Light Emitting Diodes) which
