2.5 Customizing and adjusting the draft shield (models
HF/HA/HE only)
For customizing, the slide glasses can be individually coupled with the draft shield carriage.
The draft shield has been well adjusted in the factory and should work perfectly even after
relocating or dismantling and reassembling the glass slides. Should the draft shield, however
unlikely, jam or not open and close properly, please adjust it as follows.
NOTE
If it should still not open or clamp correctly, contact Precisa Service
2.6 Setting the touchless sensors (TLS) (optional)
Touchless sensors are very helpful. They not only allow you to open and close the draft shield, they
let you perform a lot of other routines without touching the balance, too. Operating the balance by
simple hand gestures is a smart way for avoiding vibrations.
For assigning all different hand gestures to certain functions,
 Swipe left for switching the applications screen,
 Call up "Settings",
 Scroll down and call up "TLS", and
 Do all settings upon your requirements.
NOTE
Pressing "?" calls up the contextual Help which provides detailled
information about the point you currently are. For quitting Help, press
"Close".
2.7 Adjusting the balance
Since the earth's gravity is not the same everywhere, each balance must - in accordance with the
underlying physical weighing principle - be adjusted to compensate for the gravity at each location.
This adjustment process must be carried out on initial installation and after each subsequent
relocation. In order to get exact measurements, it is recommended moreover, that the balance
should also be adjusted periodically.
 Ensure the balance has reached its operating temperature.
 Swipe left for switching the applications screen and
 Call up "Adjustment".
