5.6.4.6.3 MEAS T - Measuring parameters
Tab: Method ▶ MEAS T ▶ 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 | Measurement
without drift control
Default value Measurement with drift control
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.
Measurement without drift control
The measurement is carried out without drift control if this option is ena-
bled. The measurement continues until one of the stop criterions
Measuring time or Stop measured value is met. The corresponding
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 measure-
ment 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:
Signal drift
The measured value is only accepted if the signal drift defined here has been
fallen short of.
