*) The EE895 features an exponential moving average filter which to a certain degree suppresses the influence
of short-term CO
response time of the EE895. A higher filter coefficient leads to smoother output data and to longer response time,
see figure Fig. 12. Fig. 13 shows the number of samples required to reach 63% or 90% of a CO
of the filter coefficient.
