Before doing any precision levelling it is
advised to check the calibration of the
instrument.
▪
Set up the laser on a tripod at about 30m
facing a wall or staff with a detector.
▪
Allow the instrument to level.
▪
Detect and note laser position on the
wall or staff.
▪
Without moving the tripod rotate the
instrument 180°.
▪
Detect and note laser position on the
wall or staff.
▪
Calculate the distance between the two
readings.
▪
The difference should be within 6mm at 30m.
▪
If the instrument is out of calibration it is
advised to send it in to Spot-on.
