Evacuation and Charge


Screen Shot coming soon!
The computer at this station prompts the operator to scan the serial and model numbers of the unit. The program then fetches the appropriate test parameters from the database. The operator is then prompted to press the "Start" button to begin the charge cycle. After a series of checks, the system evacuates the unit and subsequently charges the unit to the weight specified in the database for that model. At the end of the charge cycle, another series of checks ensure that the unit is charged properly and that it is safe to disconnect the unit from the station. Once the unit is disconnected, the operator is prompted to press "Start" once more to reclaim the charge hose.


In addition to the software described above, software for this station includes the following:

   1. Test Definition software
   2. Program creation and editing software
   3. Results Lookup and Standard Reporting software
