Measuring Facilities52The points can be measured intelescope face I or II, or a mixture(I + II), the sequence is of nosignificance. E.g. first point intelescope face II, last point intelescope face I + II, second pointin face I, etc.Measurements made inboth telescope faces arechecked for gross errors toensure that the same point hasbeen aimed at.If a target point is measuredseveral times in the sametelescope face the last validmeasurement is used forcomputation.Measurement restrictions:• 2 face measurementsFor measurements in 2 faces,the reflector height and therefraction coefficient must bekept the same for both facesfor the same target point,although it is permissible tochange these parametersbetween different target points.An error message will begenerated if the reflector heightchanges between face I andface II while measuring to thesame target point.• Target points with 0.000heightTarget points with 0.000height are discarded forheight processing. If target pointshave a valid height of 0.000 m,use 0.001 m to enable it for heightprocessing.
