Tipp
If by accident the display has been set too bright or too dark so that it can
not be read off, this may be changed as follows:
Switch off the UL1000 and UL1000 Fab and turn it on again. During the run-
up phase press the key no. 3 or 7 so long until the display can be read
properly again. This setting is saved to the EPROM only after confirming
this through the contrast menu. If this setting is not confirmed, the former
setting will be appled after switching on the instrument on again.
