Semi-automatic
A0042195
During semi-automatic linearization, the device measures the concentration for every table
point. The associated linearized value is entered manually. The individual linearization
values are entered via the input screen. The linearization table consists of up to 32
"measured pulse rate : concentration" value pairs.
Linearization table conditions
• The table can consist of up to 32 "concentration - linearized value" pairs.
• The table must increase monotonically
• The first value in the table must correspond to the minimum concentration
• The last value in the table must correspond to the maximum concentration
The table values can be sorted as monotonically increasing using the "Table mode -> Sort
table" function.
Edit table: the index of the linearization point is entered in this field (1-32 points)
Customer input value: measured pulse rate for the linearization point
Customer value: concentration in %.
Activate table: the "Enable" option must first be selected before the linearization table is
used. The linearization table is not used as long as "Disable" is selected.
To record a new input value, press the "Start semi-automatic calibration" button. The
measurement then starts automatically and continues, at the very maximum, for as long
as has been configured for the calibration time. However, the process can also be stopped
manually by pressing the "Stop calibration" button.
The calibration stops automatically as soon as a million pulses have been totalized.
The remaining calibration time of the semi-automatic calibration is not displayed on
the user interface.
The linearization table must be activated by selecting "Activate table" -> "Enable"
Use of the linearization module with linearization values recorded semi-
