Abstract: The suitability of a fixed or current mobile operating location for the receiver (19) in a data memory (13, 15) for picking up the consumption data (12) transmitted by a data radio channel in a wireless local data capture system (11) from consumption points (14) to a data memory (13, 15) can easily and reliably be qualitatively assessed in situ or for the purpose of remote diagnosis by virtue of a channel scan being initiated and the memory receiver (17) performing an RSSI measurement, which is preferably presented as a histogram (20) against current channel use. This renders permanent sources of interference and link budget problems in the data radio (particularly UHF) channel and also temporary sources of interference and collision problems in this channel identifiable and thereby avoids costly receiver location changes, without use of radio-specific specialist personnel, after a site has previously been selected for the receiver installation only empirically but inexpediently.
