PRE-FILL AND FILL TYPES
1. PRE-FILL TYPE
The pre-fill function is used in three fields of application:
¾large volume part test: to fill the part faster in order to reduce the cycle time (without pre-
fill time),
¾test on parts requiring an initial stretch so that they remain volumetrically stable for the
duration of the test,
¾
part proof tests, where the pre-fill
pressure exerts an elevated pressure on the test part to
ensure the part will continue to operate successfully at its working pressure.

4) Fill,
5) Stabilization,
6) Test,
7) Dump.
This function brings up the display of the words “Regulator Adjust” under “Spe. Cycle” so that
the new pressure can be set.
There are several types of pre-fill available:
1.1. STANDARD (BY DEFAULT)
Associated parameters to be set:
¾Max Pre-FILL (maximum pre-fill pressure limit),
¾C. P-FILL (pre-fill pressure instruction).
¾Pre-FILL (pre-fill time),
¾Pre-DUMP (pre-dump
time).
1.2. I
NSTRUCTION
When the pressure reaches the instruction the device runs the following step else it still filling
until the end of the pre-fill time.
Associated parameters to set:
¾Set Pre-Fill (instruction/target value),
¾Pre-FILL (pre-fill time),
¾Pre-DUMP (pre-dump time).
