15) ZERO CALIBRATION
The date under "Zero calibration" heading indicates the date when zero flow cali-
bration was performed.
If you want to recalibrate the zero flow, press the
E
button. The flow meter evaluates
the measured data automatically and if YES is set, upon confirmation of the selection
by the E button, a new value for zero flow will be set and the date of the last recalibra-
tion is updated (when NO is selected, the value for recalibration is not registered and
everything remains in original setting.
Note: Before recalibration is performed, do not forget to close the valves first and se-
cure a real zero flow (stationary medium) in the system.
16) FLOW SIMULATION
Flow simulation serves for comfortable setting and checking the systems in which the
flow meter is used without necessity to use realistic flow of medium through the meter
and without necessary installation of the meter in the pipeline. The display shows the
simulated flow and current and impulse outputs of the meter correspond to this data.
Such a simulated flow is not registered in the volume registry, of course.
WARNING! If the meter runs in simulation flow mode, it does not return automatically
after two and a half minutes as it is typical for all other modes and representations.
After termination of flow simulation mode, it is necessary to exit Parameters menu by
the (
long press >3sec) button!!!
The customer can set the value of the simulated flow. If you want to activate or deac-
tivate the simulation, press the
E
button.
