7.3.1 Test Parameters

Run the test according to the test procedure that you selected and programmed.
When switching off the unit, proceed as follows:
t
Run the test to the end.
t
Close the compressed air supply at the compressed air supply port.
t
Run the log-off function.
t
Turn off the main power switch.
In the event of a power failure, all valves will be switched to a secure state.
This guarantees that the system being tested is vented. The ongoing test is cancelled.
No test result will be available.
Loss of Compressed Air
In the event that the compressed air supply stops, the test is automatically
cancelled and an error message appears. "Target pressure not reached". The system
is vented automatically. When the supply of compressed air resumes, the unit must
be restarted and the test repeated.
To obtain reliable and reproducible test results, observe the following:
t
Run the test at room temperature (approx. 15–30°C), whenever possible.
t
During a test run, always avoid any temperature changes.
t
The upstream side of the system must be absolutely leak-free
t
Do not connect the tester to pressurized systems.
t
For filter testing: If you wish to use other types of compressed gas and| or wet-
ting fluids not specified by Sartorius Stedim Biotech, consult your local Sartorius
Stedim Biotech office or Sartorius Stedim Biotech GmbH in Germany.)
t
For the Water Intrusion Test, the surface tension of the water must be
> 70 dyn/cm.
t
Always enter correct test parameters. Incorrect test parameters will lead to
incorrect test results or erroneous evaluations.
Calibration
The Sartocheck 4 plus Bag tester should be re-calibrated at least once a year, twice
being preferable.
