Analog Input Terminals - Ametek 241CE II User Manual

Analog Input Terminals

An external water signal (a 4–20 mA input) can be brought in to the analyzer
and then displayed as water dewpoint temperature (WDP) or water content
(WCT) on the User Interface or designated V/I outputs.
To configure the analyzer to accept an external water signal and display it on
its User Interface, additional equipment must be installed on the Microcon-
troller and Termination boards (typically done at the factory). Certain analyz-
er parameters must also be calibrated to adjust input ranges. See Appendix A
for additional information.
The units of measurement (except the Remote Start option – fixed input) can
be changed from Metric to Imperial (Figure 2-4).
