9. ANGLE MEASUREMENT
3. Focus on the target with the telescope focusing ring.
* If parallax is created between the cross hairs and the target
when viewing vertically or horizontally through the telescope,
focusing is incorrect or diopter adjustment is insufficient.
This adversely affects precision in measurement or survey.
Eliminate the parallax by focusing carefully and using diopter
adjustment.
1. Display the required horizontal angle using the horizontal fine
motion screw and horizontal clamp.
2. Press {HOLD}.
Horizontal angle display blinks and the horizontal angle will be
held.
• To return to the angle status before the data is held, press any
key except {HOLD}.
3. Sight the target to set.
4. Press {HOLD}.
Angle measurement will start from the held angle.
You can switch the vertical angle display to the percentage (%)
display.
1. Press {V/%}.
• The mode switches every time {V/%} is pressed.
[--------] is displayed when a point is sighted at 45° or more from
the horizontal.
