29.10 Calibration of sensors (CAL)
29.10.1 Calibration parameters (CAL pH)
Under [Calibration parameters], the parameters influencing the
sequence of the entire calibration are defined.
Signal drift
Maximum permissible drift for the measured value acceptance, i.e. maxi-
mum change of the measured value per minute. For this value, a suitable
maximum waiting time is automatically calculated except you already have
modified this waiting time.
Input range 0.1 - 999.0 mV/min
Default value 2.0 mV/min
Selection off
off
Measured value acceptance will take place after the maximum waiting
time has elapsed.
Min. waiting time
The measured value is not accepted until the minimum waiting time has
elapsed, even if the signal drift has already been reached. The minimum
waiting time is only important for drift-controlled measurements.
Input range 0 - 999999 s
Default value 10 s
Max. waiting time
If the signal drift has been switched off or has not yet been reached, then
the measured value will be accepted when the maximum waiting time has
elapsed. As default value, a suitable waiting time for the signal drift is
automatically calculated.
Input range 0 - 999999 s
Default value 110 s
Selection off
Temperature
Temperature entered manually. The temperature is being continuously
measured when a temperature sensor is connected and when Temp.
measurement = automatic or continuous is defined (see sensor dialog
of the command).
Input range –20.0 - 150.0 °C
Default value 25.0 °C
