Testing
1. Empty measuring cup.
2. Hold tube into measuring cup, open outlet, and stop at 30 seconds.

2. Press the suction start/stop key (LED lights up). The device generates a nega-
tive pressure inside of the suction system.
The vacuum pump stops when a negative pressure of max. -60 kPa (-0.60 bar)
has been reached.
The suction system has a leak, if the vacuum pump is not deactivated. Check
the suction system for leaks and repeat test.
3. Starting suction:
Open the instrument.
The vacuum pump automatically reactivates, if the min. negative pressure is
exceeded.
4. End suction:
Press the suction start/stop key again (LED goes out).
Each successfully conducted test must documented with the test log.
