After selection of the UV measuring range calibration, the com‐
ponent to be calibrated must be selected first:
2
Select the desired component with the arrow keys and confirm
this with <ENTER>.
825
The subsequent calibration steps are performed for the SO
component by way of example.
After selection of the component to be calibrated, the adjacent
menu screen appears.
You can now use the cursor to select one of the lower lines and:
• Determine the calibration gas in line 2
8251
• Start the calibration in line 3.
You can now enter the calibration gas value. You can use the
arrow keys to change the displayed value and confirm the en‐
tered calibration gas value with the <ESC> key.

If the entered calibration gas value is okay, the analyzer waits for
1250.0mg/m3
the inflow of calibration gas.
0.0mg/m3
82512
When the analyzer detects the inflow of calibration gas, the dis‐
play changes as shown. When the measured value in the second
0.0mg/m3
line remains constant or no longer changes significantly for
more than approx. 10 s, press the <ENTER> key.

This function is used to display the drift values of the zero point
SO2 515 vpm
and sensitivity and to reset them if necessary. This function is
0
described in section Calibration: AUTOCAL/drift values
(Page 125).
82711a
In the first line of this menu display, you can re-enter the setpoint
of the pressure sensor.
999 mbar
To do this, measure a reference value, e.g. using an accurate
barometer, and change the setpoint in the first line if necessary.
