To rule out inaccuracies, the device should be placed at the measuring

location 15 minutes before taking a measurement to allow it to assume

Alignment
1
1. Bring crosshairs into focus (5)
2. Initial alignment of the telescope towards the graduated
staff is done by hand, using the iron sights.
3. Focus the image of the staff, by operating the focusing
knob, turn crosshairs onto the staff centre.
4. Make sure focusing is free of parallax. The focusing
is alright when crosshairs and graduation of the staff
don't change their positions even when looked at from
different angles (keep changing position of the eye in
front of the eyepiece).
The AL 32 has segmentation within the crosshairs for accurate targeting.
