PROGRAMMING

7.3 TEMP

7.3.1 Purpose

This section describes how to do the following:

1. Enable and disable automatic temperature compensation

2. Set a manual temperature compensation value for conductivity measurements

3. Tell the transmitter the type of temperature element in the sensor

7.3.2 Definitions

1. Au To MATiC TEMPERATu RE Co MPENSATio N. Conductivity measurements are directly affected by temperature. A

correction equation in the software automatically corrects for changes caused by temperature. in automatic tempera-

ture correction, the transmitter uses the temperature measured by the sensor for all calculations in which temperature

is used.

2. MANu AL TEMPERATu RE Co MPENSATio N. in manual temperature compensation, the transmitter uses the tem-

perature entered by the user as the reference temperature for corrections of conductivity readings. it does not use the

actual process temperature.

CAUTION

Changing the reference temperature from the default 25°C (77°F) can have large

effects on the conductivity readings and will require different temperature slopes.

7.3.3 Procedure

1. Press PRo G on the remote controller.

2. Press NEXT until the tEMP submenu appears. Press ENTER.

3. The screen displays the tAUtO (automatic temperature compensation) prompt.

Press  or



to toggle between On and OFF. Press ENTER to save.

4. if you disable tAuto, the tMAN prompt appears. u se the arrow keys to change the

temperature to the desired value. To enter a negative number, press

or 

until no

digit is flashing. Then press  or



to display the negative sign. The temperature

entered in this step will be used in all measurements, no matter what the

process temperature is. Press ENTER to save.

5. Press RESET to return to the process display.
