    • The invention is directed to a method of operating a measuring arrangement for detecting combustible gases in a gas mixture with the measuring arrangement including a display unit, a measuring unit, a detector element and a drivable compensator element. The method is improved in that the power input is minimized. This is achieved in that the detector element is supplied with the detector operating current ID during a first operating phase in the operational-ready condition; whereas, the compensator element is driven with a compensator component operating current IK1 and a first measuring signal U1 for gas analysis is formed from the voltages on the detector element and compensator element and that, in a second operating phase, the compensator element is connected in a component heat-up phase to the compensator operating current IK from the switch-in time point t0 to the time point t1 and the steady-state terminal value of the compensator voltages UK(ts) is extrapolated at the end of the heat-up phase from the increase of the compensator voltage UK(t) in the time interval t0 to t1 with a processing function and a second measuring signal U 2 for gas analysis is formed with the extrapolated terminal voltage UK(ts) and the voltage UD on the detector element.
