Preamble

E-VLT
E-VLT is a leak detector able to test large volume like EV battery housing and cooling.

E-VLT can memorise 128 different test programs and 32 batteries sets of programs.

LEAK TEST
Leak test and Desenzitizes Mode

The test pressure is applied to the input of the test part 3.
The measurement is performed by the pressure sensor 2.

1. Device
2. Pressure sensor
3. Part under test

Desensitized Mode: there is no leak fullscale. The limit is the test Pressure.

PRINCIPE OF CYCLE
The measurement cycle is made of 4 mains phases : fill, stabilization, test, dumping.

• Waiting phase
• Fill phase
• Stabilization phase
• Dumping

Leak| Leak unit| Select correct unit in the list
Max reject| Level to declare part under test as FAIL
Std Patm and Temperature| Requested parameters when specific unit as sccm is used
Offset| Manual offset that can be subtracted to the leak measurement. It is a usefull parameter to shorten stabilisation time (Reserved to expert)
Volume| It’s a necessary coeficient to convert pressure decay (in Pa) to leak (in flow unit like ml/min)
