Problem
Possible Cause
Measures
Analog Output —Flow Output
>0 to 1 mA
A reading within this range could
indicate:
–
insufficient coupling
–
that the sensor is not recognized
–
a circuit error
–
a device error
1.
Ensure that the acoustig coupling is
>60%.
2.
Check if the correct sensor is connected
and if it is not damaged.
3.
If the sensor is the correct type,
disconnect it.
4.
Reconnect the sensor again.
5.
Ensure that the circuit is intact.
6.
If the circuit is broken, fix it and restart
the measurement.
7.
Check if any errors are present and
indicated on the display.
If the problem persists, please return the
sensor and the BioProTT
TM
FlowTrack SL for
servicing.
> 20 mA
Flow value exceeds the specified
range.
Please note:
the flow range is limited
to a maximum of approximately
23 mA
1.
Ensure that the flow stays within the
specified range.
2.
If necessary, adjust the pump setting.
If the problem persists, despite the flow
being within the specified range, please
return the sensor and the BioProTT
TM
FlowTrack SL for servicing.
Analog Output —RSS Output
0 mA
A reading of 0 mA could indicate:
–
a broken circuit
–
a missing power supply for the
current loop
1.
Ensure that the circuit is intact.
2.
If the circuit is broken, fix it and restart
the measurement.
3.
Check if the device is connected to the
power supply.
4.
Ensure that the connection is tight.
5.
Check if the power supply supplies the
entire current loop.
6.
Power the device off.
7.
Power the device on again.
If the problem persists, please return the
sensor and the BioProTT
TM
FlowTrack SL for
servicing.
