3.2 Firmware
The meter supports the following firmware:
• Metrology firmware
Metrology firmware controls the measurement functions. It also provides an operating system for the
application firmware. This firmware is fixed and cannot be upgraded.
• Application firmware
Application firmware controls the functions of the meter outside of metrology. It is possible to remotely
upgrade this firmware to change the meter operation. Upgrading or updating the firmware will not affect
the meter data unless the update involves changing the parameters of such data. Information related to
load survey, transactions, events and storage or contents in billing registers are not affected during these
upgrades.
Note: The current firmware name and version are available in meter readings and on the meter’s display.
