900 Touch Control
Reference temp. standard
Reference temperature at which the calibration standard has the conduc-
tivity entered above.
Input range –20.0 - 150.0 °C
Default value 25.0 °C
Temp. coefficient
Temperature coefficient belonging to the reference temperature entered
above. With this temperature coefficient, the conductivity is converted to
the reference temperature.
Input range 0.00 - 9.99 %/°C
Default value 1.90 %/°C
Stirrer control
The parameters for the stirrer control during the calibration are edited
under [Stirrer control]. Ensure that a stirrer has been selected in the Edit
command / Stirrer dialog.
Stir solution during measurement
on | off (Default value: on)
If this parameter is activated, the stirrer will be switched on and off auto-
matically at the start or end of the measurement.
Stir before meas.
This parameter can only be edited when the parameter Stir solution
during measurement is deactivated.
If the stirrer is switched off during the measurement, it will be stirred for
the time entered before measuring.
Input range 0 - 999999 s
Default value 0 s
Pause before meas.
This parameter can only be edited when the parameter Stir solution
during measurement is deactivated.
If it is stirred before the measurement, a waiting time can be defined here
before starting the measurement. No stirring or measuring occurs during
this time.
Input range 0 - 999999 s
Default value 0 s
