Challenge Test
The Challenge test is a pre-programed test (Program 122) used for checking the unit’s
performance against a known calibrated standard.
You will need the Uson challenge unit and a calibrated micron leak.
Standard programs with the standard results use a force of 10,000 grams. The program
can be modified so the parameters more closely match the production setup, but the limits
would also need adjusting after trials.
To Perform a Challenge Test:
1.
Select
Program 122
.
2.
Adjust Regulator to approximately 0.5 bar (see Figure 16).
3.
Insert micron leak cartridge into challenge unit, resting the infill on its side, holding
the bellows still with one hand and inserting the leak with the other. The leak must be
released between tests so any remaining vacuum in the bellows is released. See
Figure 17.
