(see Chapter 2.1.3, page 12). Entering an extraction time may e.g. be
advisable if a Karl Fischer oven is used.
Range 0 ... 999999 s
Default value 0 s
Temperature
Temperature entered manually. The temperature is being continuously
measured when a temperature sensor is connected and when Temp.
measurement = automatic or continuous is defined (see sensor dialog
of the command).
Range –20.0 ... 150.0 °C
Default value 25.0 °C
Time interval MP
Time interval for entering a measuring point in the measuring point list.
The measuring point list is limited to 1000 measuring points.
Range 0.1 ... 999999.0 s
Default value 2.0 s
2.1.3 Stop conditions
Under [Stop conditions], the conditions for stopping a titration are
defined, if this does not occur automatically. This could be the case when
the endpoint set is not reached or if the stop criterion (see "Stop crite-
rion", page 10) is not fulfilled.
Stop time
The titration is stopped when the specified time has elapsed since the start
of the titration.
Range 1 ... 999999 s
Selection off
Default value off
2.1.4 Conditioning
Under [Conditioning], the conditions required for conditioning are
defined.
Conditioning
on | off (Default value: on)
If this parameter is activated, then the first time the titration is started the
working medium will be titrated to the endpoint with the specified control
parameters. The status is kept stable. The actual method run does not
begin until [START] has been pressed once more.
