Abstract (en)
A technique for securely clearing the meter after it has been disabled by a security detection scheme without returning the meter to the factory. During this technique, the meter generates a security lock code which is transmitted to a data center computer. The data center computer compares the security lock code with an internally generated security lock code. If the codes agree, the data center computer then generates a security clear code which is transmitted to the meter. The meter then compares this code with an internally generated security clear code. If these codes agree, then the meter clears the security lock flag thereby enabling the meter. As a result, the customer can subsequently remotely set the meter.
