PROBLEM TO BE SOLVED: To provide a microwave excited ultraviolet lamp system with a data logging and acquiring circuit.SOLUTION: A microwave excited ultraviolet lamp system has a data logging and acquiring circuit. The circuit stores operational data in a cache memory using a FIFO data storage protocol. The contents of the cache memory are periodically copied to a larger removable memory so that the removable memory contains a relatively long historical record of system operational parameters. The circuit includes a data port configured to load the contents of the cache memory into an external device when the device is coupled to the data port. A second data port allows the external device to supply power to the circuit so that data can be acquired when an internal power supply is malfunctioning. The data stored in the removable memory can be protected so that it can only be accessed by authorized personnel. |
