Fill Cycle

Once the calorimeter is started and the cover is closed, the fill sequence begins.
1.
The calorimeter checks the bomb ignition circuitry for continuity.
2. The water fill solenoid opens and water is pumped from the internal tank into and through the bucket that
surrounds the bomb. Overflow from the bucket is returned to the closed water tank. Because the jacket and
bucket are both filled with water from the closed water tank, initial equilibrium will be reached quickly.
3. The oxygen fill solenoid is opened and oxygen is added slowly to the bomb to bring its pressure to
approximately 30 atm.
