Measurement with drift control
The ISE calibration is carried out drift-controlled. The measurement is stop-
ped as soon as the Signal drift is reached or a defined waiting time has
elapsed.
Measured value drift
The measured value is only accepted if the signal drift defined here has
been fallen short of.
Input range 0.1 - 999.0 mV/min
Default value 2.0 mV/min
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 drift contin-
ues to be checked while the waiting time is elapsing.
Input range 0 - 999999 s
Default value 10 s
Max. waiting time
If the signal drift has not yet been reached, then the measured value will
be accepted when the maximum waiting time has elapsed. If the waiting
time has not been newly entered then a waiting time that is suitable for
the drift will be calculated automatically according to the following equa-
tion:
Input range 0 - 999999 s
Default value 110 s
Measuring interval
Time interval for entering a measuring point in the measuring point list.
Input range 0.1 - 999999 s
Default value 2.0 s
Temperature
Temperature
The temperature at which calibration is carried out can be entered man-
ually. If a temperature sensor is connected and the Temperature mea-
surement is set on the General/Hardware tab under Sensor to auto-
matic or continuous, then the temperature will be measured continu-
ously. The value is used for temperature compensation with the pH mea-
surement.
