6.4 Tests
6.4.1 Automatic self-test
On regular basis the WATERFLUX 3070 performs automatic self-tests. Tests done include an
integrity check of the hardware and the software including a memory self-test, a calculation of
the remaining battery lifetime, the battery current and checking of the coils current.
6.4.2 Verification mode
The WATERFLUX 3070 complies with the requirements of OIML R49 and EN14154 that the device
shall provide means (i.e. display reading ) for visual and unambiguous verification testing and
calibration. In order to run a test, for example a comparison with a known volume, the meter can
be set in a verification mode (menu number A2 should be set to 1).
In verification mode, menu settings are automatically adjusted in order to fulfil the requirements.
Firstly, the counters are shown with a modified number of decimals for a higher resolution on the
display. The number of decimals depends on the size of the meter. The display indicates
Pxxxxxxx. Secondly, the measurement interval is automatically set to 1 measurement per second.
Thirdly, the unit of volume is set to m
3 . The meter will automatically return to its normal
measuring mode.
6.4.3 Test mode
A test mode is available, with which a second sum counter is activated. The second sum counter
can be activated without breaking the metrological seals. Activating the second sum counter has
no effect on the measurement and does not affect the counter values.
The second sum counter starts counting from 0. The resolution of the second sum counter is 100
times larger for a more detailed reading. If, for example, the counter shows 11m3, the second
sum counter will indicate 11,xx m3.
The maximum duration of the test is 3 hours. After 3 hours the meter will automatically return to
its normal measuring mode.
WARNING!
Activating the verification mode, affects the measurement and the counter values during the test
procedure.
