Overview of Analog
Range Key functions.
Define what type of information the analog output should track
(Select Function). Choices are % O
and thermocouple millivolts. If you have the combustibles option,
you can also track combustibles.
Once you select what type of process readings the analog output
should track using the Select Function menu option, decide what
range of these readings the analog output range will cover (Set
Current Range).
Decide whether to enable output filtering, and if enabled, how much
to smooth out abrupt changes in readings (Output Filtering). Analog
Range key menu options are presented in the order in which they
appear on your control unit screen, from top to bottom. Figure 4-6
provides an overview of the functions covered by each Analog Range
key menu option.
Range of readings that the analog output represents.
