u) Reference volume
The program uses the programmed test volume to measure the normal flow at the test
output.
When the reference output volume is different from that for the test output, it is possible
to set parameters for the exact value of the reference volume to obtain correct
measurements in the event of results in negative figures.
This function may only be used on a unit of measurement of flow.
Validate the function in the
"
CONFIGURATION/EXTENDED
MENUS" menu.

v) Volume calculation
If a flow type unit is used, the parameter must be set for the total test volume. This
function can be used to calculate it.
Preparation of the instrument
9 Connect to the instrument a part with no leak.
9 Connect a known standard leak to the rapid connector on the instrument's
measurement circuit.
9 Run a special "Regulator" cycle to set the test pressure for the known standard leak
(see § 3.3.1 "Regulator adjust special cycle").
9 Carry out the special "Volume calculation" cycle by giving the leak value.
9 The value of the volume is updated within the program.
