The CLD Analyzer Module is designed to continuously analyze the sample stream.

Normally, it is never powered off except for servicing or for a prolonged shutdown.

Maximum permissible interval between calibrations depends on the analytical accuracy required, and therefore cannot be specified. Initially, the instrument should be calibrated at least once every eight hours. This practice should continue until experience indicates that some other interval is more appropriate.

The Analyzer Module will not allow the user to increase the upper limit of a range beyond the maximum range software setting. To change the Maximum Range value, select the following from the Main Menu: Technical Configuration Menu, Service Menu, Manufacturing

Data, and Analyzer Module Data. Select Maximum Range, and use the arrow keys to scroll the indicated value. The same applies for the Minimum Range value.
