5.6.4.6.3 MEAS Upol - Measuring parameters
Tab: Method ▶ MEAS Upol ▶ Properties... ▶ Measuring parameters
Command name
Name of the command.
Input 25 characters
The parameters for the measuring procedure can be defined on this tab.
Measurement
The two measuring modes Measurement with drift control or Meas-
urement without drift control can be selected.
Selection Measurement with drift control | Measure-
ment without drift control
Default value Measurement with drift control
Measurement with drift control
The measurement is carried out drift-controlled if this option is ena-
bled. 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.
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 reached 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 reached.
Measurement with drift control
If the option Measurement with drift control has been selected, then
the following parameters will be displayed:
Signal drift
The measured value is only accepted if the signal drift defined here has
been fallen short of.
