Presetting Horizontal Angles
1. Turn the instrument until the desired horizontal angle is shown on the display.
HR 60°00'00"
2. Press the "HOLD" button. HR 60°00'00" will blink on and off.
3. Aim the instrument at the target and press the "HOLD" button again. The horizontal angle will
be released from that point. HR 60°00'00" will be the start point for horizontal
angle measurement.
Measuring Vertical Angles
There are three different vertical scales to choose from when measuring vertical angles. See the
three scales in section 1.2.3., performance setup. Choose the vertical angle mode you wish to use
from among the performance setup choices.
Measuring Percent Of Grade (FIG 17)
By pressing the "V%" key, you can switch from vertical angular measurement shown in degrees
to percent of grade shown as 0 to 100% slope. The "%" symbol will be seen on the display next
to the vertical reading when in this mode.
Stadia Measurements
1. Distance measurement can be done using the stadia hairs of the reticle. (Fig .18)
2. Read the length " l " of a level rod shown between the stadia hairs. (Fig .19)
3. The distance to the target is 100 multiplied by " l ". The distance between point A and point
B is L. (Fig .20)
L=100 x " l "
