PROGRAM PARAMETERS
Use this menu to configure the measurement cycle associated to each test program.
Groups
Parameters
Descriptions
Name
Text field to easily organise program (Ex: batteryName Hous-
ing)
Test type: Leak per default
Timers
Waiting time
Time before starting the cycle
Fill Time
Necessary time to fill the battery at the pressure instruction
As soon as the instruction is reached, the fill time is shortened
Stabilisation
time
Necessary time to get a correct measurement during test time
Test time
Necesary time to get a representative measurement (20 Pa)
of the part with a leak closed to reject level (ex. leak of 0.1
Pa/s, it is advised to have 180s test time)
Dump time
Time required to dump the part through the instrument, for
housing (low pressure) couplers can be unplug
to earn time
Pressure
Pressure unit
Select correct unit in the list
Set Fill
Pressure instruction (Target)
Min and Max
pressure
At the end of filling time pressure needs to be between these
2 levels
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)
Options
Filter time
Usefull function to limit external pertubation during test time
with flow unit, this time max must be inferior to 0.5*Test time
Sign
Change the sign of the measurement, (vaccum test)
Leak search
If the part is declared as leaking, the instrument maintains the
pressure at the end of the test to let the operator look for the
leak.
The test must must be stopped manually
