Test modes
The ATEQ dedicated for sealed components can carry out the following tests:
1. large leak test only,
2. large leak test followed by a finer leak test at a smaller pressure.
These two modes can be programmed from the instrument's front panel and are called:
xLarge leak mode : Large leak test only,
xStandard mode : Large leak test, then small leak test.
Standard mode carries out a first cycle to identify large leaks and then adds a second cycle at
nominal pressure to check for small leaks.

Carrying out the cycles and settings
For the instrument to detect large leaks, two learning cycles must be carried out: one on a pass
part and one on a fail part.
Learning cycles:
"PASS part" learning cycle: this cycle is
compulsory before testing.
This P1 and P2 learning cycle
automatically calculates and identifies the
value of the pass part together with the
maximum and minimum limits (+/- 5 %
modifiable).

"FAIL part" learning cycle: this cycle is
not compulsory. It calculates the actual
minimum limit in relation to a fail part by
taking an average between the value of a
pass part and that of a fail part
