iina70e 05.fm technical handbook(1408)
5.3 Display in stand-by mode
In stand by mode the states are shown in the lower edge of the display (see Chapter
5.4.3). Furthermore calibration (Please refer to Chapter 7) can also be started in
stand by mode and purging, too (see Chapter 5.3.1)
5.3.1 Purging
Every time when the UL1000 Fab changes into stand by mode it can start purging
automatically after 20 seconds. During this purging the scroll pump is flushed through
purge connection (See Fig. 2-6/11).
When the machine is in stand by mode this operation also can be activated manually
(Key 7). By pressing the key again the purging will be discontinued. By pressing
START the activity will be discontinued, too.
5.4 The Screen in Measurement Mode
In measurement mode the leak rates can be diplayed in two different modes:
• Numerically, combined with a bargraph Fig. 5-1
• Trend mode (leak rate versus time) Fig. 5-2
In the lower right corner of the display (next to the Soft Key no. 8) you will find a
symbol that allows to switch between the display modes by pressing Soft Key no. 8.
Please refer to chapters 5.4.4 Numerical Display Mode and 5.4.5 Trend Mode for
explanations of the different display modes.
Access to calibration (Soft Key no. 5) and access to the speaker volume (Soft Keys
no. 2 and no. 3) is the same in all modes. Also the status icons in the bottom line are
in common in all display modes.
5.4.1 Call for Calibration
In all modes the Soft Key no. 5 is used to get to the calibration routine. Refer to
Chapter 7 Calibration for further information regarding calibration.
