For the conversion of the test gas concentration between %LEL and Vol.% see Information system on hazardous substances (GESTIS) of the German Social Accident Insurance (IFA)
https://www.dguv.de/ifa/gestis/gestis-stoffdatenbank/index-2.jsp or LEL values in accordance with EN 60079-20-1.
Note:
The requirements of the standards regarding error limits are valid for the whole operating range of the device, deviations are:
XXS H2 HC sensor, increased indication at -20 °C; ≤ 4.5 %LEL between -10 °C and +50 °C
XXS CO-LC sensor, increased indication at >40 °C; at zero-point <=7 ppm, test gas concentration ≤ 27 %
Dual IR Ex Sensor at measuring range 0-5 vol.% methane (CH4), the deviation from the volume fraction at 1.46 vol.% CH4 caused by added 0.075 vol.% ethane (C2H6) in air, is about + 25 % rel.
In sub-zero temperatures, the response times of the XXS CO-LC and XXS O2 sensor may be increased compared to room temperature. If necessary, check response times (see instructions for use).

Capture range
3)
3) This range of measured values is known as capture range where minor measured value fluctuations (e.g. signal noise, concentration fluctuations) does not result in a changing display. Measured values
outside the capture range are displayed using their actual measured values. By using Dräger CC-Vision the set capture range can be read out and activated/deactivated. By default, the capture range
is continuously activated in measuring mode and is disabled in calibration mode.

Cross-sensitivities exist
4)
4) The instrument responds to most combustible gases and vapours. The sensitivities differ depending on the type of gas. Dräger recommends a calibration using the target gas to be measured. Regarding
catalytic combustion sensors in the range of alkanes, the sensitivity decreases from methane to nonane. The sensitivity ratios between different gases can change as a result of sensor aging or poiso-
ning.
