7.3.3 Startup of the Radio modem AMR
The actual start of the product is automatically 10 seconds after connecting wire fraud, and any subsequent changes on switches will not have
any effect. (Be careful though of malfunctions caused by improper positioning of switch1 on the type of sensor connected).
The green LED will flash for 30 seconds, turn ON 1 second and OFF 1 second to indicate the correct startup of the counting function.
The same scenario will happen again if you subsequently connect the 2nd counter.
When installing sensors on the meters, the value of the mechanical index is never zero (even with brand new meters because they are always
tested through a few dozen rotations on a test bench); this difference is not supported by the modem AMR and must therefore treat offset
through the receiving tool.
Note: For gas meters, it may be that the modem AMR starts with a non-zero value (related to the principle of magnetic detection). Be sure to
check the offset value after startup. if an offset correction must be applied, it must be done on the collector (receiever side). It's not possible to
and apply a coorection on the Radio Modem AMR.
