Siemens ULTRAMAT 23 Series - Calibration: Ultraviolet Components; Calibration: Pressure Sensor

8.2.5 Calibration: Ultraviolet components
Choose component
: SO2 2
825
After selection of the UV measuring range calibration, the com‐
ponent to be calibrated must be selected 󹪝rst:
Select the desired component with the arrow keys and con󹪝rm
this with <ENTER>.
The subsequent calibration steps are performed for the SO
2
component by way of example.

8251
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
• Start the calibration in line 3.
Setpoint:1250.0mg/m3
82511
You can now enter the calibration gas value. You can use the
arrow keys to change the displayed value and con󹪝rm the en‐
tered calibration gas value with the <ESC> key.
82512
Span: 1250.0mg/m3
Reading: 0.0mg/m3
Connect span gas
If the entered calibration gas value is okay, the analyzer waits for
the in󹪞ow of calibration gas.
825121
Setpoint:1250.0mg/m3
Reading: 0.0mg/m3
If the reading is
stable, press ENTER
When the analyzer detects the in󹪞ow of calibration gas, the dis‐
play changes as shown. When the measured value in the second
line remains constant or no longer changes signi󹪝cantly for
more than approx. 10 s, press the <ENTER> key.
By pressing the <ESC> key you can exit the calibration procedure.
Calibration: AUTOCAL/drift values
82711a
Drift SO2 515 vpm
Zero: 0
Reset drift values
This function is used to display the drift values of the zero point
and sensitivity and to reset them if necessary. This function is
described in section Calibration: AUTOCAL/drift values
(Page 125).
8.2.6 Calibration: Pressure sensor
826
Setpoint: 1017 mbar
Reading : 999 mbar
In the 󹪝rst line of this menu display, you can re-enter the setpoint
of the pressure sensor.
To do this, measure a reference value, e.g. using an accurate
barometer, and change the setpoint in the 󹪝rst line if necessary.
