Verification of the Conductivity Sensor

The 0.01 mol KCl calibration solution can also be used for a verifi-
cation measurement.
Use the calibration solution at a temperature between 21 °C and
30 °C and allow it to reach room temperature before use.
NOTICE: The described verification procedure only works
within the specified temperature range in which the relationship
between conductivity and temperature is linear.
Make the following settings before performing the verification mea-
surement:
1 From <Menu>/<Settings>/<Sensors>/<Conductivity>/<Temp.
comp.>, select the setting "Coefficient".
2 Set the coefficient to 1.95%.
3 Create a separate ID for verification measurements and acti-
vate query of the ID. These settings can be made under the
menu items
<Menu>/<Settings>/<Identification>/<Attributes> and
<Menu>/<Settings>/<Identification>/<ID List>.
1 Carry out the measurement as described in
ductivity Measurement, p.
2 Assign the previously configured ID to the measurement.
3 After completing the verification measurement, reset the tem-
perature compensation to the previous setting.
