4.9 Activating automatic measuring range
switchover
The automatic measuring range switchover is not part of the technical
suitability 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.
