Start volume
Volume that is dosed prior to the start of the titration.
Input range 0.00000 to 9999.99 mL
Default value 0.00000 mL
Dosing rate
Rate at which the start volume is dosed.
Input range 0.01 to 166.00 mL/min
Selection maximum
Default value maximum
maximum
The maximum dosing rate depends on the cylinder volume (see chap-
ter 32, page 492).
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 to 999999 s
Default value 0 s
Initial measured value
The [Initial meas. value] is measured before carrying out the start con-
ditions. This value is used for the titration direction determination
when the titration direction is set to auto.
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.
Measuring mode Ipol:
Input range 0.1 to 999.0 mV/min
Selection off
Default value off
off
Measured value acceptance will take place after the maximum waiting
time has elapsed.
Measuring mode Upol:
Input range
0.01 to 99.90 µA/min
Selection off
Default value off
