c. A digital thermometer is recommended although a metal stem is an
acceptable alternative. Do not use a mercury and iodine glass thermometer because of

Figure 7-3. Digital thermometer with metal stem.
d. A secure 3-month supply (100 in a box) of control film that was produced with
emulsion from the same batch. Store it carefully to prevent deterioration so that the last
piece of film will have the same properties as the first.
e. You will need the recording forms and charts.
a. Clean the entire processor very thoroughly, but do not use system cleaner at
this time. Minute traces of system cleaner can contaminate the chemistry and invalidate
the initial setup controls.
Replace the developer and recirculation filter.
Ensure that the processor is functioning correctly.
