Needed Equipment
The following parts will be needed:
A blind flange 25 KF (if not assembled at the inlet port).
A helium test leak with a DN 25 KF connection (optional).
A fore vacuum pump connected to the DN25 KF flange on the side or under the
bottom (dry or wet version) for use with the PHOENIX L300i MODUL
Startup and Measure
1. Unpack the PHOENIX L300i and inspect it for any external damage (refer to
Chapter 2.1).
2. Connect the instrument to the mains power (refer to Chapter 2.4). For the
PHOENIX L300i MODUL connect the fore vacuum pump and switch it on.
3. Switch on the PHOENIX L300i by using the mains switch.
Don’t switch the PHOENIX L300i on when ambient temperature is below 10°C or
above 40°C
After power on a welcoming picture appears on the screen of the control panel Fig.
12, the status information on the speed of the turbo pump, the fore vacuum pres-
sure, the emission and the active filament are given.
The start up procedure takes less than 2 minutes and the end is indicated by a sig-
nal. The PHOENIX L300i is in standby mode now.(Fig. 12)
4. Check if the inlet port (Fig. 1/1) is blanked off. If not, please mount a blind flange
with o-ring on the inlet port.
5. Press the START button. The inlet will be evacuated and if the inlet pressure
drops below 15 mbar a measured leak rate will be displayed.
6. Press the STOP button, the PHOENIX L300i will go to standby. If you press
STOP a few seconds the inlet of the PHOENIX L300i will be vented.
7. To finish the startup procedure please proceed with step 21. For calibration pro-
ceed with step 8.
Internal Calibration
8. Proceed the internal calibration (Please refer to Chapter). For better quantitative
measurements please let the unit warm up (15 … 20 minutes).
Press Calibration (Soft Key no. 5 Fig. 12 /5) to get into the calibration menu.
Select internal (Soft Key no. 4, Fig. 12 /4) to choose the internal calibration.
The internal calibration starts automatically and takes about 30 seconds. After a
successful calibration a visual and audible signal comes up.
9. Press the STOP button Fig. 12 /12 until the message STANDBY/VENTED
appears on the display. The inlet is vented now.
Verification with an external test leak
To verify the accuracy please proceed through the following steps. A test leak is
required. If a test leak is not available please continue with step 21.
10. Remove the blind flange from the inlet port and connect the open helium test
leak to the inlet port.
