The setup wizard enables you to quickly configure the system by requiring you to
enter all of the basic parameters. Additional menu groups contain fields in which you
can enter specialized parameters and commands, allowing you to customize the
detector for a wide variety of applications.
Thermo Fisher's Dynamic Process Tracking (DPT) ensures there is no lag time in the
system's response to significant changes in level. When changes occur, the DPT feature
reduces the normal averaging time constant by a factor of eight, ensuring a rapid,
smooth output response. When the process stabilizes, a longer time constant is applied
to reduce the fluctuations inherent in radiation-based measurements. In this way,
process level changes are immediately reflected in the transmitter output, while the
effects of statistical variations in the radiation measurement are greatly reduced.
