Sequence for STAT
After the start, the activate pulse is output and the stirrer
switched on.
The start delay time is waited off.
The sample identifications and the sample size are re-
quested.
The start volume is dispensed (without controlling or
measured value acquisition and there is no monitoring
during this time) and the pause is waited off.
Then the other start conditions are worked off in the order
given below:
Start time
Start measured value
Start rate
During this time the controlling is active as well as the
monitoring. However, there is no acquisition of measured
values.
Once the start conditions have been met, measured val-
ues (time, volume) are acquired and stored in the measur-
ing point list. If monitoring of measured values and/or
temperature is active, these values will also be stored in
the measuring point list. If limits are violated it will be
marked in the measuring point list.
If a T sensor is connected, the temperature is measured
continuously (in intervals of 2 s). In pH titrations, the pH
will be corrected as a function of temperature.
Without T sensor the values are measured without inter-
rupt by T measurements. The manually set temperature is
then valid.
The titration is terminated according to the first stop crite-
rion which has been met.
Stirrer is switched off.
Evaluations and calculations are carried out.
The measuring point list is the base for evaluations (and
curves).
