4.2 Stadia Measurement
Your Northwest Instrument Automatic Level is equipped with a stadia reticle so you can make simple distance
measurements. The stadia lines are located in the reticle as shown in Diagram 4.2A below. Sight the rod, read the
two observations at the stadia lines, take the difference of these observations and multiply by 100 to obtain the
distance between the rod and the center of the instrument.
