The document provides detailed instructions on using a total station for engineering surveying, focusing on coordinate measurement, remote elevation measurement, and surface area calculations. It emphasizes the correct procedures for observing points, entering coordinates in order, and the use of the total station's functionalities for accurate measurements. Furthermore, it outlines the steps for transferring job data between the total station and external devices.

3. NOTE:
Ø Number of specified coordinate points: 3 or more, 50 or less
Ø Surface area is calculated by observing the points on a line enclosing an area in order or
reading in the previously registered coordinates in order.
Ø If two or less points are used to measure an area, an error will occur.
Ø Be sure to observe (or recall) points on an enclosed area in a clockwise or counter
clockwise direction. For example, the area specified by entering (or recalling) point
names 1, 2, 3, 4, 5 or 5, 4, 3, 2, 1 implies the same shape. However, if points are not
entered in numerical order, the surface area will not be calculated correctly.

4. Surface Area Calculation:
You can calculate the area of land (slope area and horizontal area) enclosed by three or more known
points on a line by inputting the coordinates of the points.
Input:
Coordinates : P1 (Ni, El, Z1) P5 (N5, E5, Z5)
Output:
Surface area: S (slope area and horizontal area)
Surface Area Calculation by Observing Points
Procedure:
1- Set up the instrument and enter the
instrument station data (NEZ)
2-In the second OBS mode screen, press [MENU],
then select "Area calc."
3-Select "Area calculation" in <Area calculation>.
4-Sight the first point on the line enclosing the
area, and press [OBS].

5. 5-Press [MEAS] to begin observation.
The measured values are displayed.
6-Press [OK] to enter the value of the first point in "01".
• Press [REC] in the second screen of step 5 to record code,target height,
and point name. The point name recorded here will be displayed in "01".
7-epeat steps 4 to 6 until all points have been measured. Points on an
enclosed area are observed in a clockwise or counter-clockwise direction.
For example, the area specified by entering point
names 1, 2, 3, 4, 5 or 5, 4, 3, 2, 1 implies the same shape.
After observing all necessary known points calculate the surface area for points
that have been observed, [CALC] is displayed.
8- Press [CALC] to display the calculated area.
PT: number of set points
S area: slope area
H area: horizontal area
9-Press [REC] in the screen of step 8 to record results and return to <Menu>.
Press [OK] to return to <Menu> without recording results. 5

Remote Elevation Measurement (REM):
REM Measurement
An REM measurement is a function used to measure the height to a point
where
a target cannot be directly installed such as power lines, overhead cables
and
bridges, etc.
The height of the target is calculated using the following formula.
Ht = h1 + h2
h2 = S sin θ z1 x cot θ z2 - S cos θ z1

ØOutputting JOB Data
The JOB data can be transferred from and to the instrument by two methods:
1.Outputting by using the cable
2. Outputting by using USB
