The Tracker | Nivel menu has these commands. You can also find these commands on the Tracker Nivel toolbar:
Start Orient to Gravity
Process: PC-DMIS uses the Nivel 20/230 device to create a gravity
plane and then automatically create a coordinate system based on the gravity
plane information. Once it completes the process, the monitoring process
starts automatically.
Start
Tilt Readout: Starts an X, Y tilt readout to bring the tracker
into the working range of the Nivel by adjusting the Tracker base foot
screws.
Start/Stop Monitoring: Starts or stops monitoring independent from
the Orient to Gravity process.
