3.6. VOLUME CALCULATION
This special cycle is used to calculate the volume of the test circuit.
It is only available if the unit chosen is of the flow type (cm
3
/min, cm
3
/h etc…).
To chose a unit, refer to chapter 3 paragraph 2.3 "Parameter settings".
Preparation of the instrument
9 Connect the instrument to a part with no leak.
9 Connect a known standard leak to the rapid connector on the instrument's
measurement circuit.
9 Start a special "Regulator" cycle to set the test pressure for the known standard leak
(see paragraph 3.2. "Regulator").
9 The instrument now knows the value of the test pressure and can therefore calculate
the volume of the part.
In the main menu, place the
cursor in front of the SPE
CYCLE function and confirm
using the ENTER key.
