Titration sequence of DET and MET
After the start, the activate pulse is outputted and the stir-
rer switched on.
The start delay time is waited off.
The sample identifications and the sample size are re-
quested.
The start volume is dispensed (no meas.value acquisition)
and the pause is waited off.
During the titration the volume increments are dispensed
and after each increment a measured value is acquired.
Meas.values are either acquired drift controlled
("equilibrium titration") or a after a fixed waiting time. If you
have not intentionally changed the equilibration time, it is
calculated according to the formula:
150
equilibr.time in s = —————— + 5
ûDrift + 0.01
The criterion (drift or equilibration time) which is first met
applies. This avoids "infinite" titrations. If the parameter
"signal drift" is set "OFF", the measured values are ac-
quired after a fixed equilibration time.
The titration is terminated according to the first criterion
which is met.
The stirrer is switched off.
Evaluations and calculations are carried out.
Data are outputted.
