Magnetic Detection
The SGM1430-B meter supports a mechanism to detect external DC magnets of
300 Gauss near the load side terminals. The Fraud Detection log will report a
Strong Magnetic Field followed by a Strong Magnetic Field Not Longer (Event)
when the magnetic field ceases. For more information on how to access this log,
refer to Event Logging and Errors/Alarms on page 45. Refer to the Catalogue

Memory
Processor Internal Memory
The SGM1430-B meters have 1.5 MB of flash memory for program and boot as
well as 640 KB of internal RAM.
External Serial Flash Memory
The SGM1430-B meters have 16 MB of external serial flash memory for
configuration and operational data as well as for firmware upgrade image storage.
Firmware
The firmware is the critical portion of the system that sits between the headend
system, the metrological sensors, and the devices on the HAN.
Firmware Variants
The SGM1430-B meter has a separate firmware module for the metrology
processor and for the application processor.
A single metrology firmware build is used for the single-phase (SGM1411-B and
SGM1412-B), five-terminal (SGM1415-B, SGM1416-B, and SGM1422-B), and
polyphase (SGM1431-B, SGM1432-B, and SGM1433-B) meter variants.
