6400 Operation Fill Cycle Once the calorimeter is started and the cover is closed, the fill sequence begins. Figure 3-3 Bucket Fill Flow Diagram 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.
Operation Pre-Period At the completion of the fill sequence, the pre-period begins. Figure 3-4 Pre-Period/Post-Period Flow Diagram 1. The water fill solenoid valve closes and isolates the water in the bucket from the rest of the system. Water within this bucket is circulated by the stirrer. Water continues to circulate from the closed water system through the jacket surrounding the bucket.

6400 Operation Drain At the completion of the bomb rinse sequence, the drain sequence begins. Figure 3-6 Drain Flow Diagram The water in the bucket is drained out of the bucket and routed to the drain connection. Once the bucket is drained, the calorimeter may be opened to remove the bomb head and load the next sample.
