•
Push the free end of the silicone tube onto the
nozzle of the pressure sensor.
•
CAUTION: as far as possible, do not alter the
volume in the syringe!
•
Connect the absolute pressure sensor to the
TM
3B NETlog interface and wait for the interface
to recognise the sensor.
•
The first reading appears on the interface dis-
play.
•
TM
In the 3B NETlab
enter the readings for the volume by hand in
steps of 1 ml at a time.
•
Plot the graph of the characteristic.
