4.10 Activating thermal conduction calibration (without
measured values)
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, there is 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.
Prerequisites
– The %LEL (heat tone) and Vol% (heat transfer) measuring ranges are
calibrated.
The automatic measuring range switchover is not part of the certified
measuring function.
If the function is activated, there is no blocking alarm.
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
