Manual Calibration
Manual calibration can be done setting the micro switches on PCB in the
proper combination in according with the pipe size (from d20-DN15 up to
d>200-DN>180) where sensor will be installed. Positions are reported in the
following table.
Lock position is a No Functioning Combination while the USB combination is
for accessing to the USB connection.
The setting has to be done before powering up the instrument.
F6.60 provides a frequency output (0Hz@0m/s - 800Hz@8m/s) by a
Open Collector (connectors 9-10) and an analog output (4mA@0m/s –
20mA@8m/s).
Both outputs are proportional to the flow velocity and so to the flow rate.
Moreover a Open Collector (connectors 7-8) is dedicated to specify the flow
direction.
In manual calibration the S.S.R. cannot be set and consequently used.
