QUADRANT PLATE QUADRANT PLATE COVER PENDANT CLUTCH pcx ASSEMBLY PENDANT CLINOMETER — Ceiling light projector and clino- meter ML-119. the cross wires centered upon the lower part of the most clearly defined light spot on the cloud; tighten the clutch by means of the thumb- screw. Read the elevation angle to the nearest whole degree from the quadrant. The average elevation angle obtained by three sightings should be used to obtain the cloud height. Simple triangulation then enables the cloud height to be computed by using the known horizontal distance from the observer to the projector as a baseline. The height in feet equals the distance (length of the baseline in feet) multiplied by the natural tangent of the elevation angle. The height so determined is 83.
