(3) Detach the developer replenisher gooseneck from the left side of the
developer tank and place it in a graduated cylinder of sufficient capacity. Refer to
Lesson 1, figure 1-26.
(4) Run the standard size sheet of film through the processor and collect the
developer replenisher in the cylinder.
(5) If the amount of replenisher does not correspond with the sensitized
materials manufacturer's recommended rate, adjust the stroke of the pump.
(a) To adjust the rate of replenishment, turn the volume screw on the
replenisher pump clockwise to increase the rate. Turn counterclockwise to decrease
the rate. Do not touch the locknut.
(b) Continue to adjust the volume screw and measure the replenisher
delivered into the beaker until the amount delivered matches the recommended rate.
(6) Run the film through the processor again, collecting the entire quantity
pumped for the film. If necessary, readjust the pump stroke to obtain the desired
Calibrate the fix pump head in the same way.
CALIBRATE/VERIFY THE X-OMAT X-RAY FILM PROCESSOR
a. Calibrate the Developer Thermostat. As discussed in Lesson 2, the
developer thermostat has been set at the factory to 95F (35C). If adjustment is
necessary, turn the adjusting knob in the proper direction. Refer to Lesson 2, figure
2-14. To readjust the temperature range on the thermostat, do the following.
Loosen the setscrew of the knob.
Reposition the knob to increase or decrease the temperature.
Retighten the setscrew on the flat of the
b. Verify the Incoming Water Supply. To provide the proper temperature
regulation, 30 to 65 pounds of line pressure must be supplied to both sides of the mixing
valve. The hot-water temperature must be at least 15F (8.3C) above the temperature
set at the mixing valve. The cold-water temperature must be at 15F (8.3C) below the
temperature set. Check the flow of the incoming water supply as follows:
With the wash rack removed, drain the wash tank completely.
