The options for temperature compensation are
grouped into two sets: MANUAL and AUTO
(Automatic). MANUAL temperature compensation
contains no additional options and is locked to a
specific process temperature independent of the
selected temperature sensor. If a different fitted
temperature is desired, the new temperature can be
adjusted by completing a temperature calibration to
the desired temperature value.
The AUTO compensation options are sensor group
dependent and use the measured temperature value.
AUTO compensation algorithms include the following
Temperature Compensation States:
State Function
STD.KCL Standard Potassium Chloride (KCl). Compensation is 0.1N KCl based. Available for all sensor
groups.
TC.COEF Temperature Compensation Coefficient. Compensation is based on a percent change of the
conductivity at the reference temperature per degree Celsius. Available for all sensor groups.
NAOH Sodium Hydroxide. Compensation is 0 to 15% Sodium Hydroxide (NaOH) based. Only available for
Sensor Group A.
NACL Sodium Chloride. Compensation is 0 to 20% Sodium Chloride (NaCl) based. Only available for
Sensor Group A.
HCL Hydrochloric Acid. Compensation is 0 to 18% Hydrochloric Acid (HCl) based. Only available for
Sensor Group A.
H2SO4 Sulfuric Acid. Compensation is 0 to 15% Sulfuric Acid (H
2
SO
4
) based. Only available for Sensor
Group A.
NEUTRL Pure Water – Neutral Salt. Compensation accounts for the effect of pure water with a trace salt factor
applied. Only available for Sensor Group C.
ACID Pure Water – Neutral Salt. Compensation accounts for the effect of pure water with a trace acid factor
applied. Only available for Sensor Group C.
BASE Pure Water – Neutral Salt. Compensation accounts for the effect of pure water with a trace base
factor applied. Only available for Sensor Group C.
USR.DEF User-Defined. Compensation is defined as a ratio of uncompensated conductivity over compensated
conductivity for a specific set of temperatures. Available for all sensor groups.

Temperature Compensation States of Operation
The User-Defined temperature compensation option
requires uncompensated conductivity data from the
reference temperature (typically 25°C) to the
maximum process temperature on a representative
sample of process solution. With this data, the ratio
of uncompensated conductivity to conductivity at the
reference temperature is calculated. These ratios are
then plotted against the temperature.
To illustrate the use of the User-Defined Temperature
Compensation State, an example of a possible
conductivity data set is shown below. Once the data
is plotted, the non-linear plot is segmented into five
linear sections. The break points, which are listed as
the first and third column in the table, are used for the
data that is entered into the User-Defined
Temperature Compensation States.
