4. ANGLE MEDASUREMENT

The function of angle measurement covers measuring and displaying

vertical and horizontal angles (VA and HL/HR), 0 set, horizontal set (HSet),

switching to slope (V%), switching Face Right and Face Left (R/L), etc.

4.1 Angle

0Set:

Set the current angle to 0°.

HSet:

Input an angle to set as the current

horizontal angle.

V%:

degree or gradient display

R/L:

Shift Face Left and Face Right.

4.2 HSet

Press HSet to go the screen of setting horizontal angel.

Input a value of the angle to set as the current horizontal angle. And

press OKto confirm.

5. DISTANCE MEASUREMENT

The function of distance measurement covers measuring and displaying

vertical distance (VD), horizontal distance (HD), slope distance (SD), stake

out (S.O.), and setting of measuring mode (Mode), etc.

5.1 Distance

Aim at the center of the target prism through the optical eyepiece by

adjusting the focus, and press Meas to start the distance

measurement.

Meas:

Start to measure the distance.

S.O.:

Start to stake out the distance.

Mode:

Set the measure mode

5.2 Stake Out (S.O.)

Input a distance to stake out. It could be a vertical distance,

horizontal distance or slope distance, by pressing Shft to shift the

mode.
