7. Maintenance
Measurement Section
It is very easy for spilled samples to accumulate
in the section where the sample dish is inserted,
so the supplied brushes should occasionally be
used to clean this section. It is particularly easy
for errors to arise if measurements are made when
there is sample material adhering to the electrode
plate (round metal plate).
Crushing Section
If a new sample is crushed when there are still traces
of old samples adhering to the crushing rollers,
the new sample will be contaminated with the old
sample material and accurate measurements will
be impossible. It is therefore necessary to clean the
rollers with the supplied brushes while turning them.
Sample Dish
When using the sample
dish continuously, use
the brush to remove any
sample material adhering
to the inside and back of
the dish.
<Storage>
After using the PB-3103, clean it well as described
above and then store it in a dry place where it will not
be exposed to direct sunlight. Be sure to remove the
batteries if storing the unit for an extended period of
time.
