  Lowest Detection Limit (LDL): The LDL is defined as 2 times the standard deviation  evaluated over a time period of a 2 min measurement
at stable reference conditions with set point 0 ppm. The LDL of the system can be improved by mean of averaging.

  Averaging time: An exponential moving average (EMA) is applied on measured concentration values. The averaging time expresses the
period of time of past measurements considered to compute the next averaged value. The averaging time can be set up to 600 s.
3
  Precision: The precision is defined as 2 times the standard deviation  of a 2 min measurement at stable reference conditions over the full
measuring range. The precision of the system can be improved by mean of averaging.
4
  Accuracy: The accuracy is defined as the difference between the mean response during a 2 min time interval and the reference value at
reference conditions. Variations of the operating temperature and pressure can affect the accuracy of the system.

   Lowest Detection Limit (LDL): The LDL is defined as 2 times the standard deviation  evaluated over a time period of a 2 min measurement
at stable reference conditions with set point 0 ppm. The LDL of the system can be improved by mean of averaging.
11
   Averaging time: An exponential moving average (EMA) is applied on measured concentration values. The averaging time expresses the
period of time of past measurements considered to compute the next averaged value. The averaging time can be set up to 600 s.
12
   Precision: The precision is defined as 2 times the standard deviation  of a 2 min measurement at stable reference conditions over the full
measuring range. The precision of the system can be improved by mean of averaging.
13
   Accuracy: The accuracy is defined as the difference between the mean response during a 2 min time interval and the reference value at
reference conditions. Variations of the operating temperature and pressure can affect the accuracy of the system.
