29.3 Endpoint titrations (SET)
29.3.1 Start conditions
The parameters that are carried out before the start of titration are
defined under [Start conditions].
Pause 1
Waiting time, e.g. for the electrode to settle down before a start volume is
added.
Input range 0 - 999999 s
Default value 0 s
Start volume
Volume that is dosed prior to the start of the titration.
Input range 0.00000 - 9999.99 mL
Default value 0.00000 mL
Dosing rate
Rate at which the start volume is dosed.
Input range 0.01 - 166.00 mL/min
Selection maximum
Default value maximum
maximum
The maximum dosing rate depends on the cylinder volume (see Chap-
ter 32, page 488).
Pause 2
Waiting time, e.g. for the electrode to settle down after the start or a
reaction time after the dosing of a start volume.
Input range 0 - 999999 s
Default value 0 s
Initial measured value
The conditions for the entry of the first measured value in the measuring
point list are defined under [Initial meas. value].
Signal drift
Maximum permissible drift for the measured value acceptance, i.e. maxi-
mum change of the measured value per minute. For this value, a suitable
maximum waiting time is automatically calculated except you already have
modified this waiting time.
