The hardware test is a diagnostic tool helping you in preventive maintenance as well as
service and repair. The test takes you through a number of steps testing all units that
are subject to wear and should thereby help you to find almost any problem in the
ILS500 F system.
You can choose to test according to the limits of your specific application.
1 Setup all parameters for your test object (or load desired recipe) and connect a
leak free sample.
2 Set test selection switch to ”ILS500 F + Object” for application specific hardware
test. You can also test the ILS500 F against factory specification. In this case you
should plug both test ports using the plugs delivered with the units. Remove ISO to
NPT converters if installed and install the blind plugs. Set test selection switch to
”ILS500 F plugged” for factory specified hardware test.
3 The ”Continue” button will be displayed at the end of each test step. Press
”Continue” for next test step.
Pressure and Vacuum Sensors
Zero points of pressure and vacuum sensors are tested.
Possible results:
• Zero Points are OK
• Vacuum Zero Point not OK
Offset zero point can result in:
• Incorrect gas filling
• Erroneous vacuum or pressure decay results
Notice Run through the whole sequence to interpret the results correctly.
You will need the reference table at the end of this section to help you
interpret the test results correctly. Keep this manual at hand when
performing the test.
