The TEST push button as X-RAY button is a “dead man” button, which
means thus if it is released during the examination cycle, the latter is
interrupted stopping the movements in progress. To re-start the cycle
first reset the unit by means of the key 32 (Figure 7-13), than start again
the function which was interrupted.
The following intensifying screen - film combinations are recommended
in order to obtain good quality images:

The above listed intensifying screens are all of the Green Rare Earth
emitting type.
Use of screens and films different from those stated on the table above
requires system recalibration by an Authorized Technician.
The calibration of the above mentioned combination has only an
indicative value. The effective adjustment depends on different factors,
such as the real dose emitted by the unit, the film development system
and the user predilection for more or less devise images.
The good quality of the image does not exclusively depend on
ROTOGRAPH PLUS but a great importance is to be given to the film
developer; and dark room techniques.
Therefore, it is necessary:
• to perform developer maintenance as indicated by the manufacturer
instructions;
• to check regularly the level of the used chemical substances,
substituting them at time intervals as indicated by the manufacturer
instructions, usually a direct function of the number of radiographs
developed and chemicals concentration.
