4. In order to start the measurement operation, press "START/STOP" on the
control unit.
The test object is evacuated and the pressure is displayed during the
pump-down operation.
Once the measuring pressure is reached, the measured value display
appears (
see Chapter 6.5.4).
If the background leakage rate (< 1E-09 mbarl/s) has been reached, the
test object can be pressurized with helium.
The display shows the leakage rate of the test object.
5. Press the "START/STOP" button to stop the measurement.
TITANTEST™ will switch back to "Standby" and the test object will be
vented.
6. Separate the test object from the device.
7. Connect the next test object.
6.5.2 Measuring in "Sniff" operating mode
1. Connect any required accessories or equipment.
Ensure that a sniffer line is connected and the test port is blank-flanged.
2. Check whether the parameters shown in the "Standby" window apply.
The device is ready if the display shows the "Standby" window after the
run-up of the device.
Ensure that TITANTEST™ is set to "Sniff" operating mode.
3. In order to achieve the most precise possible measuring results, allow
the device to warm up for approx. 30 minutes (
see Chapter 6.1: "Switch-
ing on the device", page 21).
4. In order to start the measurement operation, press "START/STOP" on the
control unit.
The measurement window is displayed.
5. In order to account for the background concentration of tracer gas and
to suppress them during the measurements, hold the sniffer tip away
from possible sources of gas and briefly press the "Zero" button on the
device or on the button on the handle.
For more on the "ZERO" function, see Tab. 20: "Filter and ZERO", page 44.
6. Hold the sniffer tip close to the possible leak source and sniff the test ob-
ject.
The tip may touch the test object.
If you want to test a weld seam or similar, you must guide the tip along
the path at a speed of less than 2.5 cm/s (1 in/s).
When you check a spot, hold the sniffer line at it for at least 1 second.
