6.4 Tests
6.4.1 Automatic self-test
On a 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.
If required, warnings and error messages as a result of the self-test are available on the display
of the converter and optionally via the status outputs.
6.4.2 Verification mode
The WATERFLUX 3070 complies with the requirements of OIML R49 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. First, 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. Second, the measurement interval is automatically set to 1 measurement
every 2 seconds. Third, the unit of volume is set to m
3
. To go back to the standard mode menu
number A2 should be set to 0.
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.
