Method

Speed at which the start volume is added until the start slope is reached.
The maximum dosing rate depends on the cylinder volume of the used ex-

change unit or dosing unit.

Pause

Pause

[ 0 ] ... 999999 s

Waiting time, e.g. for the electrode to settle down after the start or a reac-
tion time after the addition of the start volume. The pause follows at the end
of all the start conditions.

Stop conditions

Conditions for stopping the titration. The stop conditions are checked at the same
time and the condition which is fulfilled first stops the titration.

Command name

25 characters, [ DET U # ]

Name of the command.

Stop volume

0.00000 ... [ 100.000 ] ... 9999.99 mL, off

(Titrando)

0.000 ... [ 100.000 ] ... 9999.99 mL, off

(Titrino)

Stops when the given volume (including start conditions) has been added
after the start of the titration. The stop volume should be adapted to suit the

sample weight or the titration vessel size.

Stop measured value

-2000.0 ... 2000.0 mV, [ off ]

(Titrando)

-2000 ... 2000 mV, [ off ]

(Titrino)

Stops when the preset value for a measuring point has been exceeded or
undercut since the start of the titration.

Stop EP

1 ... [ 9 ], off

Stops when the given number of EPs has been found.
Volume after EP.

Volume after EP

0.01000 ... 9999.99 mL, [ off ]

(only Titrando)

When the number of equivalence points defined under

Stop EP

has been

found this volume will be added. In this way the curve can be continued af-
ter the equivalence point has been reached.
