terval between the end of conditioning and the end of the determi-
nation. If the drift is known for a longer period of time then this can
be calculated for the EP-volume by manual drift correction. The re-
sult always indicates whether it has been drift-corrected or not.
• Drift value (d): Volume drift for manual drift correction
• Measured value display: The volume drift can be shown continu-
ously during conditioning.
Editing the conditioning options:
• Cond. stop volume: If the entered volume has been added before
conditioning has been completed then the process will be stopped.
If conditioning is continued by pressing [Start] again then the ti-
trant volume that has already been added will not be taken into ac-
count; addition starts again from zero. The stop volume should be
adapted to the size of the titration cell in order to prevent any over-
flow.
• Cond. stop time: If conditioning takes longer than the time entered
here then the process will be stopped.
• Start reconditioning at end of method: If this option is
switched on then reconditioning will only start when all method
commands have been processed. Otherwise reconditioning would
start immediately after the titration command. This function must be
activated if other commands follow the SET command that must not
be allowed to take place at the same time as conditioning. Exam-
ple: emptying the titration cell and then adding new solution.
The parameters for Control device, Sensor, Dosing device and
Stirrer are described in Section 4.1.5.
