1. A process for changing a behavior of at least one mobile gas measuring device, the process comprising the steps of:
generating data by the at least one mobile gas measuring device, which is located in the monitored area, based on a gas concentration measurement and transmitting the data to a central data processing unit;
comparing the data generated based on the gas concentration measurement with at least one limit value and outputting an information signal based on an undershooting or overshooting of the limit value by the at least one mobile gas measuring device or by the central data processing unit or by both the at least one mobile gas measuring device and the central data processing unit;
detecting a current position of the at least one mobile gas measuring device;
dividing the monitored area into a plurality of zones and setting zone-specific parameters for each of the plurality of zones; and
setting or changing or setting and changing an operating mode, which comprises a plurality of functions, to a changed-over operating mode, which comprises less than the plurality of functions, based on the current position of the gas measuring device and based on at least one of the zone-specific parameters.
