ABSTRACT:
A communications link is evaluated between a communications module connected to a meter and a remote reading terminal. The communications link is established between the meter's communications module and the remote reading terminal under given operating conditions. Then, under substantially the same operating conditions, at least one of the communications parameters of the remote reading terminal is controllable attenuated, and a detection operation is performed to determine whether the communications link between the meter's communications module and the remote reading terminal is still established. Communications parameters of the remote reading terminal that are controllably attenuated, either alone or in combination, include transmitter power and receiver sensitivity.
