Measurement with drift control
The measurement is carried out drift-controlled if this option is
enabled. The measurement is stopped as soon as the defined Signal
drift or the Stop measured value is reached or a waiting time has
elapsed. The corresponding parameters are not visible if this option is
disabled. This option is not available for the 712 Conductometer.
Measurement without drift control
The measurement is carried out without drift control if this option is
enabled. The measurement continues until one of the stop criterions
Measuring time or Stop measured value is met. The correspond-
ing parameters are not visible if this option is disabled.
NOTE
A constant measured value is often only achieved after a certain time,
as mixing and possibly 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
measurement is particularly advisable in such cases, as the measured
values are not applied until equilibrium has almost been achieved.
Measurement with drift control
If the option Measurement with drift control has been selected, then
the following parameters will be displayed:
Measured value drift
The measured value is only accepted if the signal drift defined here has
been fallen short of.
