The kit includes: an optical level, plastic carrying case, adjusting pin, hexagon wrench, user manual, and warranty.
Setting and leveling
•
Place the tripod legs on the ground and adjust the tripod to the user's eye level.
•
Place the device on the tripod and screw it tight.
•
You can carry the device by lifting the tripod. Hold it vertically in order not to damage the device.
•
Use the leveling screws (9) to position the bubble level (10) in the center (Fig. 1). The device is leveled when the bubble is in the center.
Aiming and focusing
•
Remove the eyepiece cover (12). Aim the device at a bright object or hold a white sheet of paper in front of the objective lens (7), then turn
the eyepiece focusing knob (13) until the dark black crosshairs can be seen clearly.
•
Aim the device at the leveling rod. If necessary, use the optical peep sight (6) for easy aiming.
•
Turn the focusing knob (5) until you can see the graduation marks of the leveling rod clearly (Fig. 2).
•
Align the crosshairs exactly to the center of the leveling rod by turning the horizontal drive screw (8).
Height difference measurement
•
Put the leveling rods A and B in the vertical position. Place the device between the leveling rods A and B (Fig. 3).
•
Focus the optical level on the center of the rod A. Record the height value of the leveling rod at the center of the crosshairs.
•
Focus the optical level on the center of the rod B. Record the height value of the leveling rod at the center of the crosshairs (Fig. 4).
•
Calculate the height difference by subtracting the smaller height value from the larger one.
In Figure 3, for example, the height difference is 0.565m. Subtract the value of height B from the value of height A.
1.78 – 1.215 = 0.565
