Automatic start [Autom. start]

Automatic start

on | off (Default value: off)

If this parameter is activated, the determination is automatically started
when the measured voltage suddenly changes. This setting will be ignored
as long as the working medium has not been conditioned.

Threshold value

If the change in voltage is higher than this value, the determination will
automatically be started.

Range

0 ... 999 mV

Default value

50 mV

Conditioning options [Cond. options]

Stabilizing time

Waiting time, during which the measured drift has to be smaller than the
start drift defined until Conditioning OK is displayed. The start drift is
defined in the dialog Edit command / Conditioning.

Range

0 ... 999999 s

Default value

0 s

Cond. stop time

Maximum permissible time over which conditioning may take place. Con-
ditioning is stopped when the specified time has elapsed.

Range

Delay reconditioning

on | off (Default value: off)

If this parameter is activated, the conditioning will not start before all the
method commands have been processed. Otherwise, the conditioning will
immediately start after the titration command.

Note

This parameter must be activated if commands follow which must not
run simultaneously with the conditioning.

Example: Emptying the titration cell followed by adding new working
medium.
