The tape must be glued smoothly on the surface. The measuring accuracy decreases if the tape is not even!
Before gluing the magnetic tape and the cover tape onto the surface, they should be left lying on the mounting
surface for ca. 30 minutes so that the temperature matches. This prevents strain in the tape due to thermal ex-
pansion.
Mounting steps:
1. Thoroughly clean the surface ( 7.2.3)
2. Acclimatization: let magnetic tape and cover tape adjust their temperature
3. Remove the protection foil from the magnetic tape
4. Glue magnetic tape under great pressure
5. Thoroughly clean surface of magnetic tape
6. Remove the protection foil from the cover tape
7. Glue the cover tape under great pressure
8. Safeguard the ends of the cover tape against peeling off, e.g. by using end caps ( 9.1)
