1 Place the meter in a socket.
2 Apply power to the meter.
3 Remove the meter from the live socket.
4 Replace the meter in the socket.
The meter has incremented the removal tamper counter.
The CP1SR uses the power outage (the meter being removed from a live socket) in
conjunction with the meter being shaken simultaneously to increment the power removal
counter.
The inversion counter increments when the meter senses reverse current flow. The
metrology board senses reverse power flow and sends this status to the CP1SR personality
module. The CP1SR then increments the counter and transmits the count.
As part of the 96-bit Standard Consumption Message, 4 bits are allocated for tamper
indications, which include the power removal and meter inversion counters. The table below
shows the removal and inversion information based on the reported tamper count.
