900 Touch Control
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.
Measuring mode pH, U and Ipol:
Input range 0.1 to 999.0 mV/min
Selection off
Default value off
off
Measured value acceptance will take place after the maximum waiting
time has elapsed.
Measuring mode Upol:
Input range
0.01 to 99.90 µA/min
Selection off
Default value 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 to 999999 s
Default value 0 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 to 999999 s
Default value 1 s
