value of "0" turns it off.
4. Adjust the instrument position using the laser dot until it is centered over the ground mark.
5. Center the bubble in the circular level by adjusting the tripod legs (shorten the leg farthest from the bubble
or lengthen the closest leg). Repeat as necessary.
6. Center the bubble in the tubular level:
a. Loosen the horizontal clamp. Rotate the alidade until the plate level vial is parallel to the line connecting
foot screws A and B.
b. Turn foot screws A and B simultaneously in opposite directions to center the bubble. The bubble moves in
the direction of the thumb's movement.
7. Rotate the alidade 90° so the level vial is perpendicular to the line of screws A and B. Turn foot screw C to
center the bubble.
8. Rotate the alidade back 90° and check the bubble position. If not centered:
a. Turn foot screws A and B equally in opposite directions to move the bubble halfway back to center.

Measures points that cannot be directly occupied by a prism or are not visible, by measuring to an offset
(eccentric) point and applying corrections.
6.3.3.1 Accessing Remote Measurement
On the second page (P2) of the Program Menu, select "1. Remote Measurement" (or press [1]).
6.3.3.2 Offset by Single Distance
Measures a hidden point by measuring to an offset point and inputting the horizontal offset distance and
direction from the offset point to the target.
1. Place the prism on an offset point near the hidden target. Measure the horizontal distance from the offset
point to the target.
2. In the Remote Measurement menu, select "3. Offset by 1 Distance" (or press [3]).
3. Sight the offset point prism and press [Measure].
4. Press [OK]. Enter the offset distance and the direction (Left/Right/Front/Back) from the offset point to the
target.
5. Press [OK]. The instrument calculates and displays the distance and/or coordinates of the hidden target.
6. Use [SHV]/[XYZ] to toggle display formats. [Record] saves the result.
6.3.3.3 Offset by Two Distances
Measures a hidden point lying on a straight line defined by two offset points (Prism1 and Prism2). Requires
inputting the distance from Prism2 to the target.
1. Place two prisms (Prism1 and Prism2) on a line passing through the hidden target point.
2. In the Remote Measurement menu, select "4. Offset by 2 Distances" (or press [4]).
3. Sight Prism1 and press [Measure]. Press [OK].
4. Sight Prism2 and press [Measure]. Press [OK].

5. Enter the distance from Prism2 to the hidden target point.
6. Press [OK]. The instrument calculates the hidden target's data.
7. Use [SHV]/[XYZ] to toggle display formats. [Record] saves the result.
6.3.3.4 Offset by Angle
Measures a hidden point by measuring the distance to an offset point (on the same radius from the instrument
as the target) and then sighting the angle to the hidden target.
1. Place the prism on an offset point approximately the same distance from the instrument as the hidden
target.
2. In the Remote Measurement menu, select "5. Offset by Angle" (or press [5]).
3. Sight the offset point prism and press [Measure].
4. Precisely sight the hidden target point and press [OK].
5. The instrument calculates the hidden target's data.
6. Use [SHV]/[XYZ] to toggle display formats. [Record] saves the result.
6.3.4 REM (Remote Elevation Measurement)
Measures the height of an object (e.g., wire, bridge) where a prism cannot be placed directly, by measuring to a
prism placed directly below/above the object and then sighting the object itself.
1. Place the prism directly under or over the target object. Measure the prism height (RH).
2. In the Program Menu, select "2. REM" (or press [2]).
3. Press [Height] to set Instrument Height (HI) and Prism Height (RH).
4. Sight the prism and press [Measure].
5. Sight the target object and press [REM]. The height of the object relative to the ground (or the prism) is
displayed.
6. Press [Stop] then [OK] to finish.
6.3.5 Resection
Determines the coordinates of the instrument station by measuring angles and/or distances to multiple known
points. Can calculate only elevation (Height Resection) or full coordinates (Coordinate Resection).
6.3.5.1 Accessing Resection
In the Program Menu, select "5. Resection" (or press [5]).
6.3.5.2 Coordinate Resection
Calculates the station's N, E, and Z coordinates.
1. In the Resection menu, select "1. Resection" (likely corresponding to Coordinate Resection).
2. Input the coordinates (N, E, Z) and target height (TH) for the first known point. Press [Next Point].
3. Repeat step 2 for at least one more known point (minimum 2 points required, more improve accuracy). Use
[Recall] to load points from memory.
4. After entering all points, press [Measure] (or a similar button to start observations).
5. Sight the first known point. Press [Measure] to take a distance measurement, or [Angle] for an angle-only
measurement.
6. Confirm the measurement. Repeat for all other known points.

When enough measurements are taken (e.g., 2+ angles, or 1+ distances + angles), the instrument
calculates the station coordinates (N, E, Z) and displays the results, often with residuals.
7. Press [Record] to save the new station coordinates. Press [OK] to finish.
6.3.5.3 Elevation Resection
Calculates only the station's Z coordinate (elevation).
In the Resection menu, select "2. Elevation Resection" (or similar).
The procedure is similar to Coordinate Resection but only requires (or uses) vertical angle and distance
measurements to known points for calculating height. Input or recall known point elevations (Z) and target
heights.
