How long can the TSI be operated unattended?
As long as power is maintained to the instrument, and the mirror kept free of dirt, deposits, or bird debris, the TSI can be operated unattended indefinitely. The networking connection between a TSI-440 and the PC acquiring and processing the images is a key reliability issue. You also need to think about AC power quality from a system-level point of view. On the TSI-880 an integral UPS keeps the system running during brief outages and shuts the system down in an orderly fashion if power is lost for more than a few minutes. The TSI-880 image processing system is self-contained and up to 720 images are locally buffered until the connection is restored and data collection via YESDAQ resumes.
