Received back from Licor. This 7550 sn AIU-1866 went back to Licor for a power problem. Licor replaced the 7550 main power supply under warranty, subjected the units to environmental tests and verified the operation of the units. It was shipped with 7500A sn 75H-2669 (nothing wrong with the 7500A, it was just the sensor attached when the box died) |
