Measuring the

temperature

For the temperature compensation, it is required to measure the tem-
perature of the test sample.
You have the following possibilities of measuring the temperature:

z The temperature sensor integrated in the sensor measures the tem-

perature automatically (example: TetraCon 325).

z Automatic temperature measurement by the external temperature

sensor (accessory) NTC30 or Pt1000. This method is required
when using conductivity measuring cells without integrated temper-
ature sensor. Connection of the temperature sensor, see
section 1.3 S

OCKET

FIELD

z You measure and enter the temperature manually.

Note
The instrument automatically recognizes the type of the used tempera-
ture sensor (NTC30 or Pt1000). The temperature sensor is shown on
the display by TP.

If you use a conductivity measuring cell electrode without a tempera-
ture sensor, proceed as follows:

Note
When determining the cell constant without a temperature sensor, also
set the current temperature of the control standard manually using the
<

▲ > <▼> keys.

Measure the current temperature of the test sample using a
thermometer.

Enter the temperature on the instrument: Set the temperature
value of the test sample using <
