8.2.3.2
Calibration: O2 measuring range: Calibrating the O2 zero point
You can use this function to re-adjust the zero point of the H
2
S
sensor with nitrogen. Connect nitrogen to the sensor and
commence the calibration with <ENTER>.
Following calling of the correction function, the current oxygen
value is displayed in the second line. If the displayed value
does not deviate by more than 1% from the set value, it is used
as the new zero point.
If the deviation is greater than 1% (as is the case in the exam-
ple on the left, see third line), a fixed default value is used in-
stead.
Note
The gas exchange takes place very slowly with low oxygen concentrations. In such cases we
recommend flow periods of approx. 30 minutes before you use the current value.
8.2.3.3
Calibration: O2 measuring range: Calibrate measuring range
You can calibrate the sensitivity of the electrochemical O
2
sensor using this function.
The adjacent menu display appears when you select the func-
tion.
Start the calibration procedure by positioning the cursor to the
3rd line and pressing the <ENTER> key.
The analyzer interrupts the current measurement when the
calibration procedure is selected and expects a flow of calibra-
tion gas.
The entered setpoint is displayed in the first line and the actu-
ally measured value in the second line.
If the analyzer recognizes a flow of calibration gas, the display
changes as shown. If the measured value in the second line
remains constant for more than approx. 10 s or does not
change significantly, press the <ENTER> key.
