Upper and lower angle measurement:
Upper and lower angle means the angle included between any two targets (or two ends of a target) against the vertical line on
the reticle.
An upper and lower angle measurement is similar to measuring the azimuth. When the upper and lower angle measurement is
very small, aim the cross center of reticle at lower part of the target, read the scale value at the top of the target. The value is the
measured mils of angle included between the upper and lower parts. As shown in Fig. 4, the value of the lower part is 40, the
angle included between the upper and lower parts of the target is 0-60 (60 mils).
Fig. 4
When the target's upper and/or lower limits are larger than the mils on the reticle, it can be measured in steps and the angle
can be obtained by summing up the value of each step. (The process will be similar to the one that is discussed in the linear
measurements section above.)
