test.
WARNING
Risk of explosion!
Only for CatEx sensors: The full-range modeonly applies for methane in the air. Any
other gas composition has an impact on the measured signal, may cause an
incorrect display of the results and may cause permanent damage to the sensor.
► Only use the full-range mode to measure methane in the air.
The automatic measuring range switchover can only be activated for the
DrägerSensor CatEx SR sensor (order no. 6851900) with methane as the
measured gas.
If automatic measuring range switchover is activated, only the X-am 5800 has an
automatic switch to volume percent range when 100 % LEL methane is exceeded.
If the “No measured values in Vol% range” feature has been selected, the over
range in %LEL will continue to be shown instead of the measured values in the
volume percent range.
When returning to the range of <100 % LEL methane, the measured value display
alternates with the indicator (circular arrow) during the transition.
Prerequisite:
– The %LEL (heat tone) and Vol% (heat transfer) measuring ranges are
calibrated.
1. Activate automatic measuring range switchover with the Dräger CC-Vision PC
software.
2. Where applicable, select the “No measured values in Vol% range” feature with
the Dräger CC-Vision PC software.
