Calibration date
Date and time of the calibration.
Calibration method
Name of the method with which the calibration was carried out. If the cal-
ibration data has been entered manually, then manual will appear here.
User
Short name of the user logged in during calibration or when the calibra-
tion data was entered manually. If work is not carried out using login then
the user logged in under Windows will be entered automatically.
History graph
The 10 last values for the selected colorimetric sensor are displayed in
each case on the tab Coefficient of determination. The values are pre-
sented in different colors, the same as with the History table:
￭ blue, if the value has been assigned automatically by a method.
￭ black, if the values have been entered manually.
If a limit value is defined, then the warning limits are shown in orange
and intervention limits in red. 1 is always displayed thereby as the upper
warning and intervention limit.
[Limit values]
Opening the dialog window Limits for colorimetric sensor - 'Sensor
name' for the quantity selected in the graph in which the warning and
intervention limits for the coefficient of determination can be defined (see
Chapter 6.8.3.6, page 1457). These limits apply only for the graph. No
monitoring takes placed during the calibration. The limits set on the tab
Limit values apply for the monitoring during the calibration (see Chapter
6.8.3.4, page 1455).
[Delete history]
Delete the history for the colorimetric sensors.
6.8.3.6 Colorimetric sensor history - Limits
Dialog window: Configuration ▶ Colorimetric sensors ▶ Edit ▶ Properties... ▶ His-
tory ▶ [Limit values] ▶ Limits for colorimetric sensor - 'Sensor name'
In the dialog window Limits for colorimetric sensor - 'Sensor name'
you can define warning and intervention limits for the coefficient of deter-
mination. If you have defined limits then these will be shown in the graph
in orange for warning limits and red for intervention limits. However,
whether these limits are observed is not monitored, i.e. exceeding these
limits does not trigger any action. For monitoring during calibration, the
limits set on the Limit values tab apply.
