makes contact with the spindle.

3.5 Fitting a sample container
support
During a test, the sample container (glass
beaker or can) is held in position at the
correct height by the sample container
support. Two supports are supplied with the
instrument - a large one and a smaller one.
Which support you use depends upon the
size of the sample container.
The sample container support is held in
position on the base by the locating plug.

1. Place the locating plug into the recess
on the base of the instrument.
2. Place the large sample container
support onto the locating plug.
