CALIBRATE MODE
The Calibrate Mode of Operation provides the ability
to calibrate the sensor and temperature inputs.
These functions include process variable,
temperature, edit, and reset calibration. Figure 10
shows the Calibrate States and key assignments for
each state.
Process Variable Calibrate State
The Process Variable Calibrate State contains one
calibration procedure. This calibration procedure is a
smart one-point calibration routine that allows for
single point and dual-point calibration. By initiating
calibrations at two different conductivity values having
ample separation, the transmitter automatically
adjusts the offset and slope in order to obtain the best
sensor performance. Since this routine only uses the
most recent calibration data, calibration can be
conducted throughout the sensor’s life thus ensuring
consistent sensor performance. If an incorrect
calibration has been entered, the Reset Calibrate
State provides the ability to return the transmitter
calibration to factory settings.

Mode of Operation.
Since the transmitter can be configured as a
Conductivity or Concentration analyzer, the smart
one-point calibration routines will automatically set the
units of calibration to be the same as those for the
measured process value. Thus, a Conductivity
Analyzer type uses conductivity units and a
Concentration Analyzer type uses the user-defined
units set in the Configure Mode.

Invalid calibration values will generate the text string
BAD.CAL (i.e., Bad Calibration), and the calibration
value will not be accepted. If the values are valid, the
Efficiency (shown as a dimensionless value) will be
shown. Pressing the NEXT key displays the Offset
value. At this point, the user can return to the
Process Variable Calibrate State by pressing the
NEXT key or to the Measure Mode by pressing the
Exit to MEASURE key.
Temperature Calibrate State
The Temperature Calibrate State is a smart
calibration routine that allows for both single- and
dual-point calibration. By calibrating the temperature
at two points that are at least 20
o
C apart, the
transmitter adjusts the offset and slope. Since this
routine only uses the most recent calibration data,
calibrations can be conducted throughout the sensor’s
life to ensure accurate measurement of the
temperature. If an incorrect calibration has been
entered, the Reset Calibrate State can restore the
calibration to factory settings.
