STANDARD STRAIGHTNESS
Coarse adjustment
Position the laser transmitter at one end of the measurement object, on
the object or on a tripod.
Position the receiver as close as possible to the laser transmitter. Adjust
the height of the laser transmitter and the receiver to get the laser beam
to hit the centre of the target.
Move the receiver as far from the laser transmitter as possible but still
on the measurement object. Adjust the laser beam with the adjustment
screws on the laser transmitter so it hits the centre of the target. Repeat
until the laser beam hits the target at both ends of the measurement
object.
