Computer Enhanced Response (CER) uses a dynamic moisture
calibration technique to extrapolate the moisture level to the end
point when making measurements in abrupt "dry down"
conditions. The system response time depends on the relative
change in dew point. For a change from ambient moisture levels
to trace levels, the unit can respond in 3 to 5 minutes.
The accuracy of enhanced response is
sensor would have read if it were allowed to reach equilibrium
with the gas. To ensure that CER is as accurate as possible, your
application should:
•
have a reasonably constant final dew point and flow rate.
•
have a minimum flow rate of one standard cubic foot per
hour (SCFH).
•
operate at atmospheric pressure (0 psig).
•
have an actual moisture content equal to or wetter than a
dew/frost point of
