Energy Scan Failure, Instrument Error, Establish Scan Time Out, Fatal Scan Error

It's unlikely to be a source problem. The expected, average life of a laser is 4 years. If this energy you report is with an open beam, then you have a more complex issue. The energy I would expect with and open beam, with any accessories removed, would be >5500 counts. I depends on the type of accessory plugged in that will determine the energy otherwise. Scan errors can be caused by weak lasers. You can email me if you need further assistance. Iberridge@isocount.com
