Dangerous gases
Danger of poisoning!
> Observe safety regulations/accident prevention regulations
when handling test gas.
> Use test gases in well ventilated rooms only.
Application of test gas via service adapter (0554 1205) is
recommended, or apply test gas directly to the probe tip to
avoid possible absorptions in the gas path.
1.Select the parameter: [▲], [▼] → [OK]
2.[Change] → Enter the test gas concentration (nominal value).
3. Apply test gas to the sensor.
4.Start calibration: [Start]
5. Accept the nominal value once the actual value is stable
(adjustment): [Adjust]
-or-
Cancel (no adjustment): [esc]
6. Save changes: [Finished]
Perform calibration / adjustment of the CO
2
-(IR) sensor
Check the CO
2
-(IR)-sensor with the absorption filter to obtain
accurate readings. The displayed CO
2
-value should be <0.3%CO
2
.
If the value is higher, perform calibration and gradient adjustment.
