The factor to calculate the total dissolved solids is set to 1.00 in the
factory. You can adjust this factor to meet your requirements in the
range 0.40 ... 1.00. The factor is set in the Measurement menu for
the parameter, TDS.
The stability control function (AutoRead) continually checks the stability of the
measurement signal. The stability has a considerable impact on the reproduc-
ibility of measured values (see section 11.2.3 A
page 71).
The Stability control function checks whether the measured values are stable
within the monitored time interval.

The minimum duration until a measured value is assessed as stable is the mon-
itored time interval. The actual duration is mostly longer.
With the HOLD function, you can freeze the current measured value. The dis-
played measured value stops changing until you switch the HOLD function off.
1. Freeze the measured value with
The [HOLD] status indicator is displayed.
2. Release the frozen measured value again with
The HOLD function is switched off.
The [HOLD] status display disappears.

10.1.2 Measuring the temperature

For reproducible conductivity measurements, it is essential to measure the
temperature of the test sample.
The temperature is automatically measured by the temperature sensor
(NTC30 or Pt1000) integrated in the sensor.
The conductivity sensor CO 11 has an integrated temperature sen-
sor.
