M2 and the standard water meter so that the returned field strength value is around -80dBm. At this time,fix the position of HAC-MLW-F-T2-M2 , and use the magnet to trigger the standard water meter to obtain10 packets of remote data. The average of the field strength value of 10 packets’ data is the standard field strength value. The standard field strength value is used in the supported software to judge qualified threshold value of the field strength. - Page 12 HAC-MLW Metering Module User Manual V1.0 The interface of parameters setting is below: Obtain the remote field strength value:...
