When approaching the reference angle (<10°) iLevel will automatically fade in the high precision disc readout, which rotates at 10 times the rate of the normal readout. By this it allows for high precision measurements – much more precise compared to a bubble level/spirit level.
In the picture below the following markers are relevant for high precision measurements:
- Marker 1 highlights the high precision disc (automatically fades in when approaching the target angle).
- Marker 2 shows the reference angle marker.
- Marker 3 highlights the gap in the high precision disc.
For measurements at high precision align the gap in the disc (3) with the reference angle marker (2).
