Hilti PRA 90 Manual De Instrucciones página 20

3.3 Automatic alignment
The tripod can be automatically aligned with the HiltiPR 30­HVS A12, PR 30­HVSG A12 or the PR 300­HV2S
rotating laser. These rotating lasers are specifically matched to the PRA 90 and support three-device
communication between tripod, rotating laser and associated laser receiver/remote control unit.
Using these three components together, a laser plane can be aligned onto a precise point automatically.
Only the target height has to be indicated with the laser receiver/remote control unit and the PRA 90 moves
the laser plane of the rotating laser exactly to this height.
Automatic alignment is not possible when other rotating lasers are used.
