For exact method of activating/terminating laser beam emission, refer to the instructions in the manuals of respective software. · The Laser indicator is turned on and the Laser pointer function is operating. mark on the left of the screen blinks while the · The beam of the sun is strong and visual confirmation is difficult in daytime when outdoors. · The laser beam is designed not to be able to observe through the telescope. · Please visually align the laser beam to the target and mark the center. Confirm the alignment (horizontal and vertical) before measuring when performing accurate work like stake out when using the Laser pointer function. · Please do not look at the laser source of beam directly. 23 3. PREPARATION FOR SURVEYING 3. 1 Centering and leveling of the instrument [S etting up the instrument and the trip od] Adjust the tripod legs so that a height suitable for observation is obtained when the instrument is set on the tripod. Hang the plumb bob on the hook of the tripod, and coarse center over the station on the ground. At this time, set the tripod and fix the metal shoes firmly into the ground so that the tripod head is as level as possible, and the plumb bob coincides with the station on the ground. If the tripod head is mis-leveled by the action of fixing the metal shoes into the ground, correct the level by extending or retracting each leg of the tripod. Setting up and turn on. 24 3. 2 Laser plummet Turn on the laser plummet function. How to activate/terminate the laser beam emission differs depending on application software. For exact method of activating/terminating laser beam emission, refer to the instructions in the manuals of respective software. The brightness adjustment step of the laser is 10 steps. Match the position by the tripod so that the laser mark coincides with the ground mark. Rotate the instrument by 90°, and confirm the vial of the the electronic vial is at the center at any position. Correct the bubble with the leveling screw when the bubble comes off from the center. · The laser plummet spot can become difficult to see in bright sunlight which makes it difficult to perform the occasional check. In this case, use your foot or the carrying case to make a shadow over the laser position. · The laser plummet is adjusted to be within +- 0. 8 mm at the instrument height of 1. 5m at factory shipping. · Please do not look at the laser source of beam directly. 25 3. 3 Leveling Tripod is adjusted according to the following points by extending or contracting the legs so that the bubble of the Circular vial goes to the center of the circle. · Shorten the leg at the side of the bubble or extend the leg opposite of the bubble to position the bubble in the center of the vial circle. · All three legs are extended or contracted until the bubble is in the center. During this process, the foot is not placed on the tripod leg point and the position of the tripod points do not change. Rotate instrument horizontally and make two Leveling screws arbitrarily chosen parallel to the display. [. . . ] Correction is then carried out based on the following formula. K: Atmospheric Correction Constant P: Atmospheric pressure (hPa) t: Temperature(°C) Distance after Atmospheric Correction D = Ds (1+K) Ds: Measured distance when no Atmospheric Correction is used. 6. 2 hPa and mmHg conversion table [Conver ting from hPa to mmHg] [Conver ting from mmHg to hPa] 42 6. 3 Error when no atmospheric correction is made When measurement is carried out with no Atmospheric Correction (with the settings fixed at a temperature of 15°C and an atmospheric pressure of 1013 hPa or 760 mmHg), the Error per 100 meters in temperature and pressure will be shown in the tables below. · When the actual pressure is 1013 hPa (760 mmHg) and the temperature is 25°C, conducting the measurement with the temperature left at 15°C will result in the measurement being short by 0. 9 mm per 100 meters. [Error table: When hPa (15°C, 1013hPa as standard)] [Error table: With mmHg (15 °C, 760mmHg as standard)] 43 6. 4 Atmospheric refraction and earth curvature correction · Atmospheric refraction and earth curvature correction refers to correcting both the bending of the light beam caused by atmospheric refraction and the effect on the height differential and horizontal distance caused by the earth curvature. · Correction called "atmospheric refraction and earth curvature correction" is initiated to correct error when the slope distance and vertical angle are caused to determine the horizontal distance and the height differential, with this instrument, the following formula is used to correct these factors. · Calculation formula when atmospheric refraction and earth curvature correction parameter is set to "ON": Corrected horizontal distance (H) Corrected vertical distance (V) · Calculation formula when atmospheric refraction and earth curvature correction parameter is set to "OFF": S: : K: Re: Slope distance Vertical angle from horizontal Atmospheric refraction coefficient (0. 14 or 0. 2) Diameter of earth 6378137m 44 6. 5 Distance range Generally speaking, the maximum range which can be measured varies considerably depending on the atmospheric conditions.
