Proc Temp Lo Alert Threshold— Process Temperature Low Alert Threshold is the process variable temperature, in
temperature units, which, when exceeded, will set the Temperature Low Alert.
D Proc Temp— Displays the process temperature stored in the instrument.
D Proc Temp Offset— Bias to improve the accuracy of the (RTD) temperature measurement used to provide
compensation for process­temperature­related density changes.
D Temperature Deadband— The Temperature Deadband is the amount the temperature, in temperature units, must
change to clear a temperature alert, once it has been set. The deadband applies to all the temperature alerts. See
figure 4‐8. In firmware revision 8, the Temp Alert Offset is displayed incorrectly when the units are DegF. (The
number displayed is 32 more than the actual deadband.)
