Degas the sensor head
Avoid that the plug connector gets in contact with water.
Take care that the piston never recoils abruptly as this might
damage the pressure transducer (max. 3 bar)!
1. Take the syringe that belongs
to the sensor unit attachment.
Draw up 15 ml of water.
Degas the water as described
before and push out all air from
the syringe.

2. Place the acrylic sensor head
attachment onto the sensor
head. The sensor head should
sit firmly on the O-Ring. Do not
attach the tube yet.
3. Fill up the acrylic
attachment with deionised
water using the droplet
syringe.
Fig. 23
Attach the tube and the
vacuum syringe. Draw it up
until the black spacer snaps in.
Air bubbles will assemble
inside the syringe.
To avoid damaging the
pressure transducer, please
securely hold the piston so it
will not suddenly recoil.
Release the spacers and allow
the piston to return slowly.
Only water should flow back
into the acrylic attachment.
Take off the tube and push the
assembled air out of the
syringe.
