7.4 Test Start/Stop
Prerequisites
See chapter “Start-up of the detector”
Test method
The test method is chosen depending on the part to be tested.
For more information about leak detection test methods, see Leak detector compendium on the
www.pfeiffer-vacuum.com website.
There are 2 possible test methods:
●
Hard Vacuum
●
Sniffer
Hard vacuum test
The test can also be started using a remote control (accessory): see the remote control operating in-
structions.
1. Select the ‘hard Vacuum’ test method (see chapter “Test method”).
2. Select the test mode (see chapter “Test mode”).
3. Set the reject point and warning set point if necessary (see chapter “Set points”).
4. Put the detector on ‘Stand-by’ mode.
–
In ‘Stand-by’ mode, the leak rate displayed corresponds to the detector’s background.
5. Carry out air inlet by pressing the [VENT] function key.
6. Prepare the part/installation to be tested (see chapter “Part/installation connection to be tested”).
–
Spray method
–
Connect the part/installation to be tested to the leak detector inlet port.
–
Evacuate the air from the part/installation to be tested.
–
Bombing method
–
Place the part to be tested in a pressurization chamber with the tracer gas.
–
Remove the part to be tested from the chamber and put it in the test chamber connected
to the leak detector inlet port.
7. Start the test by pressing the START/STOP button.
–
Spray method
–
Spray the tracer gas on the points on the part that are likely to leak.
8. The various test steps are displayed.
When the detector has reached the most sensitive test mode, wait for the measurement to stabi-
lize: the measurement displayed corresponds to the measured leak rate.
9. Stop the test by pressing the START/STOP button.
Sniffer test
1. Prepare the part/installation to be tested.
2. Select the ‘sniffer’ test method (see chapter “Test method”).
3. Set the reject point and warning set point if necessary (see chapter “Set points”).
4. Put the detector on ‘Stand-by’ mode.
5. Connect the sniffer probe (accessory).
6. Start the test by pressing the START/STOP button.
