28.3.1 Measuring parameters
Under [Measuring parameters], the parameters influencing the run of
the entire measurement 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.
NOTICE
A constant measured value is often only reached after a certain time, as
mixing and the reaction itself require a certain time. The response time
of an electrode can also increase with time, i.e., reaching a constant
measured value takes longer and longer. Drift-controlled measured
value acceptance is particularly advisable in such cases, as the measured
values are only accepted when equilibrium has almost been reached.
