6.5.1 Measuring in the operation mode "Vacuum"
WARNING
Risk of injury due to suction at the test connection flange
In the vacuum mode, the device can draw in parts of the body that block the inlet
flange.
Always use an inlet filter.
Keep body parts away from the inlet flange.
1. Connect all required accessories or devices. Remove the blank flange at the test
port and establish the connection to the test object.
2. Check if the parameters displayed in the "Standby" window are correct. The
device is ready when the "Standby" window appears on the display after the
device starts up. Make sure that the device is in "Vacuum" operation mode.
3. In order to obtain the most precise measurement results possible, allow the device
to warm up for approx. 30 minutes.
4. To start the measuring process, press "START" on the control unit. The test object
is evacuated and the pressure is displayed during the pumping process. As soon
as the measuring pressure is reached, the measurement view appears. If the
background leak rate (< 1E-09 mbar l/s) is reached, then helium can be applied to
the test object. The display shows the leak rate for the test object.
5. Press the "STOP" button to stop the measurement. The device switches back to
"Standby" and the test object is vented.
6. Disconnect the test object from the device.
7. Connect the next test object.
