The camera has not reached the proper temperature for operation. The SECTOR Imager 2400 and SECTOR Imager 6000 cameras must cool to -25°C and -35°C, respectively, before the instrument becomes operational.
Check the camera cooling status (Tools > Status). The temperature should be dropping toward the operating temperature. Wait up to 45 minutes for the camera to stabilize at the correct temperature. This is a normal function of turning on the instrument. Restart the software. Check the temperature again. Contact MSD instrument service at 1-301-947-2057 for assistance if the camera temperature is not dropping.
