The figure shows that the evaluation also requires measured values from
the measuring point list after the equivalence point as well.
For the recognition of the EPs found the set EP criterion is compared with
the ERC (Equivalence point Recognition Criterion) found. The ERC is the
first derivative of the titration curve combined with a mathematical func-
tion which is more sensitive for flat jumps than for steeper ones. EPs
whose ERC is smaller than the defined EP criterion will not be recognized.
The ERC is displayed in the results dialog for each discovered and recog-
nized EP. If you adjust the EP criterion later in order to recognize more or
fewer EPs, then you can reevaluate the determination ([Recalculate]
function in the results dialog).
28.1.5 Control device
The control device the determination is carried out with is selected under
[Control device]. Control devices are defined under System
▶ Device
manager.
NOTE
This button will only be shown when, in addition to the Ti-Touch, a
Sample Processor has been configured as control device.
Control device
Selection of the control device from the list of devices. Only those devices
are displayed which are able to carry out the command.
Selection Selection of configured control devices
28.1.6 Sensor
The parameters for the sensor are edited under [Sensor].
Measuring input
Selection of the measuring input the sensor is connected to. The selection
is not dependent on whether the control device has one or two measur-
ing interfaces.
Selection 1 | 2
Default value 1
Sensor
Selection of the sensor from the sensor list. The selection depends on the
measuring mode. Sensors are defined under System
▶ Sensors. You can
also enter a sensor name which is not contained in the sensor list. When a
determination is started there is a check whether the sensor is contained
in the sensor list.
