1) Calibration of gas transmitter at 50 % of the full-scale deflection.
2) Relative change of signal at 50 %LEL (Dräger PIR 7000) or at 5 vol. % (Dräger PIR 7200).
3) The measured value response times may vary with other approved substances. Depending on the accessories used longer response times are possible.
