The choices depend on the measurement being made.
Stabilize and Stabilize time: For the controller to accept calibration
data, the concentration must remain within a specified range for a
specified period of time. The default values are 0.05 ppm and 10 sec-
onds. Using a small stabilize value and a long stabilize time is the
best protection against calibration while a reading is still changing.
Dual range cal: The Model 499ACL-02 total chlorine sensor from
Rosemount Analytical can become non-linear at high concentrations
of chlorine. Dual range calibration allows the analyzer to correct for
the non-linearity of the sensor. For more information see Section 9.4.
