§1.6 Data Integrity and Built-in Time-Keeper
All user-inputted configuration values are retained in the built-in non-volatile flash memory that
can store them for over 100 years, even if power is lost or turned off. Password protection is provided
to avoid inadvertent configuration changes or totalizer resets.
A time-keeper is integrated in the flow meter for the index of date totalizing and works as the time
base of flow accumulation. It keeps operating as long as the battery’s terminal voltage is over 1.5V.
In case of battery failure, the time-keeper will not keep running and it will lose proper time values.
The user must re-enter proper time values in case the battery becomes totally exhausted. An improper
time value affects no other functions but the date totalizer.
