The utility meters contain integer values. It is possible to enable/disable the utility metering modifying

the contents of the address 2036h (see EEPROM map).

Their resolution is 0.1 m

and, after reaching 99999999.9 m

the total meters will be reset and start

again from 0. The day/night gas meters full maximum value is 50000000.0 m

To reset an utility meter two write requests (write 0000h) are to be sent to the instrument: the first to

reset the two most significant bytes, the second to reset the two less significant bytes.
