 Type: Integer, Input
 Default Value: 1
 Description: Frozen measurement checking

FRZE_CHK is a checking mechanism to ensure that a measurement has variation and is not frozen at the same value for repeat cycles of the application. If the measurement does not change, it is marked as bad and not used in the application. FRZE_CHK is useful for certain types of measurements that are known to periodically fail and stay at a constant value, such as gas chromatographs. FRZE_CHK can also detect when the application is cycling at a faster rate than the measurement device can deliver a new measurement. FRZE_CHK may be undesirable if the sensor resolution gives a false indication of a frozen measurement when it is actually a steady signal and poor sensor resolution. When FRZE_CHK is OFF, there is no checking of the difference from the prior measurement. BNDS_CHK, FRZE_CHK, and MEAS_CHK are options regarding data cleansing before it enters the applications.
