5.3 Display in stand-<strong>by</strong> mode<br />
In stand <strong>by</strong> mode the conditions are shown in the upper edge of the display<br />
(see Chapter 5.4.3). Furthermore calibration (Please refer to Chapter<br />
7) can also be started in stand <strong>by</strong> mode and purging, too (see Chapter<br />
5.3.1)<br />
5.3.1 Gas Ballast/Purge<br />
In stand-<strong>by</strong> mode the gas ballast of the fore pump can be switched on/off<br />
manually or via softkey 7. The gas ballast is for abolishing a too huge<br />
helium background. Additionally a condensation of water vapour in the<br />
pump will be avoided. After 20 minutes the machine closes the gas ballast<br />
valve automatically to limit the loss of oil.<br />
This function can be chosen automatically for the PhoeniXL300 dry and<br />
PhoeniXL300 Modul. Every time the unit changes into stand-<strong>by</strong> mode it<br />
can start automatically after 20 seconds. During this purge the membrane<br />
or sroll pump will be purged <strong>by</strong> the valve V6.<br />
Attention In case there was a large quantum of water vapor pumped with<br />
the machine please activate the gas ballast for about 20 minutes<br />
before running the machine down.<br />
5.4 The Screen in Measurement<br />
Mode<br />
In measurement mode the leak rates can be displayed in two different<br />
modes:<br />
� Numerically, combined with a bargraph Fig. 14<br />
� As trend: numerically, combined with a diagram (leak rate versus time)<br />
Fig. 15<br />
In the lower right corner of the display (next to the Soft Key no. 8, Fig. 14<br />
and Fig. 15) you will find a symbol that allows to switch between the display<br />
modes <strong>by</strong> pressing Soft Key no. 8. See chapter 5.4.4 and 5.4.5 for<br />
explanations of the different display modes.<br />
Access to calibration (Soft Key no. 5, Fig. 14 and Fig. 15) and access to<br />
the speaker volume (Soft Keys no. 2 and no. 3, Fig. 14 and Fig. 15) is the<br />
same in all modes. Also the status icons in the upper line are in common<br />
in both display modes.
