Sensitometric checks may be carried out to evaluate if the performance <strong>of</strong><br />
films in the automatic processors is being maximized. These checks involve<br />
measurement <strong>of</strong> basic fog level, speed and average gradient made at 1° C<br />
intervals <strong>of</strong> temperature. The range <strong>of</strong> temperature measurement depends on<br />
the type <strong>of</strong> chemistry in use, whether cold or hot developer. These three<br />
measurements: fog level, speed, and average gradient, should then be<br />
plotted against temperature and compared with the manufacturer's supplied<br />
figures.<br />
