temperature will be measured continuously. The value is used for
temperature compensation in pH measurements.
• Time interval MP: Time interval for entering a measuring point in
the list of measuring points. The list of measuring points can con-
tain max. 1000 measuring points.
• Pause: Waiting time, e. g. for electrode equilibration, after the start
of the method.
The conditions for terminating the dosing are defined under Stop con-
ditions
:
• Stop volume: Stops when the preset volume has been added since
the start of the dosing. You should adapt the stop volume to suit the
size of your vessel in order to prevent it from overflowing.
• Stop time: Stops when the preset time has elapsed after the start
of the dosing.
If several stop conditions have been set then the first criterion to be ful-
filled will stop the dosing.
• Filling rate: Rate at which the dosing cylinder is refilled after the
dosing. The maximum filling rate depends on the cylinder volume of
the exchange or dosing unit used (see Section 3.8.6).
The parameters for monitoring the measured value as well as the tem-
perature
are defined under Monitoring. Remote signals or RS com-
mands can be assigned to the monitored quantities. This can be used,
for example, to switch a thermostat on/off if necessary.
• Measured quantity: Select the measured quantity being moni-
tored.
The remaining parameters are described in the section about the STAT
titration (see Section 4.1.4).
The item Control device is mentioned in Section 4.10.1, the parame-
ters for the Sensor, Dosing device and Stirrer are described in Sec-
