4 Error messages
The meter constantly performs a self-diagnosis and can
recognise and display various metre and installation errors.
If the error message F0 is displayed, flow measurement is
not possible, e.g. due to air in the volume measuring
section.
The error messages F1, F2 and F5, F6, F8 indicate that the
temperature sensors are defective.
If the error message F4 is displayed, the battery is empty.
The error messages F3, F7, F7F and F9 indicate that the
electronics are defective.
In all cases, notify the Service Department.
