Sequence with DOC
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.
Once the start conditions have been met, measured val-
ues (time, volume) are acquired and stored in the meas-
uring 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 determination is terminated when the end of the
measured value ramp is reached, i.e. after the sweep
time. If measured value monitoring is active, the current
measured value also must have reached the end of the
ramp.
The stirrer is switched off.
Calculations are carried out.
Data are output. The measuring point list is the base for
curves.
