Self test (menu 2.3.1)
The self test routines test the hardware and have a duration of about 10 seconds.
If there is no error, "OK" is displayed, otherwise "not OK". The type of error can be read in the
menu 2.1 Device Status.
Display test (menu 2.3.2)
The LCD is checked with this menu item. The display is dark for about 5 seconds and then bright
for about 5 seconds.
Simulation (menu 2.4)
The display and output values to be simulated can be selected in individual submenus. The
setting becomes active after confirming the selected value. If an error is pending, only the
display value can be simulated. The output will continue to indicate an error signal unless the
errors are suppressed, see menu 2.2 Suppress err. (Both). The two warnings "P/F too high" and
"US gain too high" do not influence the outputs during the simulation. An active simulation is
indicated on the display by a blinking letter S.

Measuring functions (menu 3)
Flow, Sound Velocity and Amplitude US (menus 3.1, 3.2 and 3.3)
In this menu the three measuring values Flow (menu 3.1), Sound Velocity (menu 3.2) and
Amplitude US (menu 3.3) are parameterized.
All submenus (menu 3.x) are divided further for setting of subsequent values:
• Unit
• Range (Lower Value (for Flow not selectable - always 0) and Upper Value)
• Limits (Lo alarm limit, Hi alarm limit and Hysteresis)
• Time constant (damping)
Note
When switching between different units a rounding-off may need to be corrected manually.
Density (menu 3.1.4)
After entering units the display will automatically step into Density.
