Test of parts
The test can be started by START button. When using the test chamber TC1000, the
test starts automatically when closing the chamber lid. After the setted cycle time is
expired or the measured leak rate has gone below the trigger level the test stops and
the chamber will be vented. The test can be stopped any time by STOP button.
After starting, the test procedure runs according to the setted measurement period:
1 Remaining measurement time
Shut down
When the test chamber should remain under vacuum after switching off the UL1000
or UL1000 Fab, push the button (cup of coffee), follow the instruction on the display
and switch off the leak detector.
This function can also be used when a test of parts should be interrupted due to a
brake. You can start the measurement cycle again by pushing the button RESTART.
