Any changes to the transmitter configuration must be

saved. Pressing the Exit to MEASURE key prompts

the user to “SAVE?” their changes. Pressing the YES

key saves the new configuration and returns the

transmitter to the Measure Mode. The NO key

discards the changes and returns the transmitter to

the Measure Mode. Upon exiting from the Modify

state, the TB mode is returned from Out-Of-Service to

its previously set state.

The Modify Configure State contains all the available

settings that establish the functionality of the

transmitter. Upon receipt of the transmitter, the

default configuration (unless otherwise specified by

the customer when ordering the transmitter) will be

active once the transmitter has been powered. See

the Configuration Data Sheet at the end of this

manual for default configuration settings. Before

installing the transmitter, the configuration should be

modified to reflect the final installed application. The

Table below describes each of the Modify Configure

States and their function.

State Function

ANALYZR Used to define the type of analyzer. Choices

include Conductivity and Concentration.

TMP.SNS Used to define the type of temperature

sensor. Choices include None, Pt100, 3k

Balco, and 4.75 kohm Standard Network.

TC.TYPE Used to define the type of temperature

compensation. Choices include Manual

(0.1N KCl based), and Automatic, which can

be set to one of the following: Standard KCl

(0.1N KCl based), Temperature Coefficient

(%/

C), 0 to 15% NaOH, 0 to 20% NaCl, 0 to

18% HCl, 0 to 20% H

, .Pure Water

Neutral, Pure Water Acid, Pure Water Base,

and User-Defined.

DIAGS Used to set the sensor diagnostics ON or

OFF.

Analyzer State

The Analyzer State sets the type of measurement

(i.e., Process Value) and sensor type. The

measurements are conductivity and concentration.

The Conductivity setting displays the Process Value

using the engineering units of either mS/cm or µS/cm.

The Concentration setting converts the measured

temperature compensated conductivity to a solute

weight percentage using either one of the canned

concentration algorithms or a user-defined curve fit.

Concentration units are set to percent or can be can

separately defined for a user-defined curve fit.

States of Operation

The Conductivity Analyzer State contains three

choices for four-electrode sensor groups: A, B, and C.

The Sensor Group must be entered and correspond

with the conductivity sensor being used with the

transmitter. The measurement range for each sensor

group is listed in the Specification Section. Since

ABB four-electrode Conductivity Sensors have unique

cell constants that are defined by the physical

orientation, surface area of the electrodes, and the

measured solution voltage set by the electronics of

the transmitter, only ABB TB4 sensors are

recommended for use with the TB82EC FF

Transmitter.

The Concentration State converts conductivity values

to concentration units. This state applies

temperature-compensated conductivity

measurements to a pre-defined or user-defined
