AirDistSys 5000 6 –Operator’s Manual
Preparation for measurement:
1. First install the measurement transducer or probe
on a tripod.
2. Check if the openwork basket (4) is on the
shielding tube (3). If not put openwork basket (4)
on the shielding tube (3). Be particularly careful
not to damage the speed sensor (1). To this
purpose check if the shielding tube (3) is on the
end of the probe completely covering the speed
sensor and the clamp screw (5) is properly
locked (it does not move!). Put on the openwork
safety basket (4) only then when the sensor (1) is
covered by the shielding tube (3).
3. Loosen the clamp screw (5) and move the
shielding tube (3) with the openwork basket (4)
towards the holder uncovering the sensors (1) and
(2).
4. Lock the clamp screw (5) so that the speed sensor
(1) was in the middle of the openwork basket (4).
5. After the measurements move the shielding tube
(3) back on the sensors (1) and (2).
6. Connect the SensoCable to the one of RJ45
sockets on the back wall of the transducer casing
and to the SensoBox adapter (SensoBee wire-less
transmitter or SensoConnect USB interface). Use
the second RJ45 socket to make connection
between the transducers.
7. Turn on the power supply. The power led on the casing should blink firstly for a few seconds and next
will remain ON. If the led blinks permanently it means that is the error. The case of the error might to
be too low voltage of power supply caused for example by unloaded batteries.
Remarks:
1. The speed sensor (1) must be protected during transport by the shielding tube (3). Note that the
clamping screw (5) has been properly lock.
2. The openwork safety basket (4) should be put on and put out only then when the speed sensor (1) is
covered and secured by the shielding tube (3).
3. Use the openwork basket (4) if you are not sure of the safety of the sensors during measurements.
