When reflected light from the prism is received a buzzer sounds. This function is good for easy collimation when the target is difficult to find. Operating procedure Operation Display distance measurement mode or page 3 in the coordinate measurement.
11 SETTING THE PRISM / NON-PRISM CONSTANT VALUE 11 SETTING THE PRISM / NON-PRISM CONSTANT VALUE The prism constant value of Topcon is set to zero. When using prisms other than Topcon’s, it is necessary to set the prism constant correction value of that specific prism. Once you set the correction value for prism constant, it is retained after power is OFF. Note: Confirm the non-prism constant value is set at 0 when measuring target such as walls in Non-prism mode.
12 SETTING ATMOSPHERIC CORRECTION 12 SETTING ATMOSPHERIC CORRECTION The velocity of light through air is not constant and depends on the atmospheric temperature and pressure. The atmospheric correction system of this instrument corrects automatically when the correction value is set. 15°C/59°F, and 1013.25hPa / 760mmHg / 29.9 inHg is as a standard value for 0ppm in this instrument. The values are kept in the memory even after power is OFF. 12.

17 CHECK AND ADJUSTMENT 17 CHECK AND ADJUSTMENT 17.1 Checking and adjusting of instrument constant Note: Each of the Prism mode and Non-prism mode has instrument constant. You must obtain the instrument constant of prism mode. If you reset the instrument constant of the prism mode, you must vary the non-prism constant (Non-prism-short, Non-prismlong) by the same quantity as the amount of increase or decrease of the instrument constant of the prism mode.
17 CHECK AND ADJUSTMENT 17.2 Checking the Optical Axis To check if the optical axis of EDM and theodolite are matched, follow the procedure below. It is especially important to check after adjustment of the eyepiece reticle is carried out. 1) Position a prism about more than 150m apart from GPT-2000 series . 2) After the power switch ON, collimate the center of the prism by prism mode.
17 CHECK AND ADJUSTMENT 10) Move the collimating point to the center of prism gradually until buzzer sound starts. Turning the horizontal tangent screw to be one to two level of SIG value to adjust the collimating point same as step 6 procedure. 11) Note horizontal angle same as step 6 procedure. 12) Calculate the average value of step 6 and 10. [Example] Step 6 : Step 11 : 0°00'00" 0°08'20" Average value 0°04'10" 13) Climate to the center of prism.
17 CHECK AND ADJUSTMENT 17.3 Checking/Adjusting the Theodolite Functions ● Pointers on the Adjustment 1) Adjust the eyepiece of the telescope properly prior to any checking operation which involves sighting through the telescope. Remember to focus properly, with parallax completely eliminated. 2) Carry out the adjustments in the order of item numbers, as the adjustments are dependent one upon another. Adjustments carried out in the wrong sequence may even nullify previous adjustment.
17 CHECK AND ADJUSTMENT 17.3.1Checking /Adjusting the Plate Level Adjustment is required if the axis of the plate level is not perpendicular to the vertical axis. ● Check 1) Place the plate level parallel to a line running through the centers of two leveling screws, say, A and B. Use these two leveling screws only and place the bubble in the center of the plate level. 2) Rotate the instrument 180° or 200g around the vertical axis and check bubble movement of the plate level.
17 CHECK AND ADJUSTMENT 17.3.3Adjustment of the Vertical Cross-hair Adjustment is required if the vertical cross-hair is not in a place perpendicular to the horizontal axis of the telescope ( since it must be possible to use any point on the hair for measuring horizontal angles or running lines). ● Check 1) Set the instrument up the tripod and carefully level it. 2) Sight the cross-hairs on a well defined Point A at a distance of, at least, 50 meters (160ft.) and clamp horizontal motion.
17 CHECK AND ADJUSTMENT 17.3.4Collimation of the Instrument Collimation is required to make the line of sight of the telescope perpendicular to the horizontal axis of the instrument, otherwise, it will not be possible to extend a straight line by direct means. ● Check Eyepiece 1) Set the instrument up with clear sights of about 50 to 60meters (160 to 200 ft.) on both sides of the instrument. 50ｍ 2) Level the instrument properly with the plate level. 3) Sight Point A at approximately 50 meters (160 ft.
17 CHECK AND ADJUSTMENT Note: 1 2 First, loosen the capstan adjustment screw on the side to which the vertical cross-hair line must be moved. Then tighten the adjustment screw on the opposite side by an equal amount which will leave the tension of the adjustment screws unchanged. Revolve in the counterclockwise direction to loosen and in the clockwise direction to tighten, but revolve as little as possible. Perform following adjustment after completing above adjustment . Section 17.3.
17 CHECK AND ADJUSTMENT 17.3.6Checking / Adjusting the Laser Plummet (For Laser Plummet type) ● Check 1) Turn on the laser plummet and coincide the center of the laser with a measuring point. 2) Rotate the instrument 180° or 200g around the vertical axis and check the measuring point. If the laser is properly centered in the measuring point, adjustment is not required. Otherwise, adjust in the following manner.
17 CHECK AND ADJUSTMENT 17.3.7Adjustment of Vertical Angle 0 Datum If when measuring the vertical angle of target A at telescope position normal (direct) and reverse settings, the amount of normal and reverse measurements combined is other than 360° (ZENITH-0), half of the difference from 360° is the error amount from corrected 0 setting. Carry out adjustment. As adjustment for vertical angle 0 setting is the criteria for determining instrument coordinate origin, use special care for adjustment.
17 CHECK AND ADJUSTMENT 17.4 How to Set the Instrument Constant Value To set the Instrument constant which is obtained in Section 17.1 “Check and adjusting of instrument constant”, follow as below. Note: Each of the Prism mode and Non-prism mode has instrument constant. You must obtain the instrument constant of prism mode.

18 PRECAUTIONS 18 PRECAUTIONS 1) For transportation, hold by the handle or yoke of the instrument. Never hold by the lens barrel as it can affect the fixing bracket inside and reduce the accuracy of the instrument. 2) Never expose the instrument without a filter to direct sunlight. It may damage the components inside the instrument. 3) Never leave the instrument unprotected in high temperature. The temperature inside instrument may easily reach up to 70°C or above and will reduce the service life.

APPENDIX APPENDIX 3 Dual Axis Compensation Inclination of the vertical axis with respect to true vertical will result in incorrectly measured horizontal angles. The extent of the error in horizontal angle measurement due to axis tilt depends on three factors : ● the amount of the tilt of axis ● the elevation of the target ● the horizontal angle between the direction of till of the vertical axis and the target.
APPENDIX It is clear from the table that dual axis compensation has the most benefit when the elevation of the target is greater then 30° and the axis is tilted more than 10". The entries indicated in bold in the table show, in fact, that for many common surveying applications i.e. target elevation <30° and axis error <10", virtually no correction would be required. Dual axis compensation is especially suited then for applications where the sights are very steep.
APPENDIX 4 Precaution when Charging or Storing Batteries The capacity of battery will be affected and its service life shortened in any of the following cases while it is recharged, dischrged or stored. 1) Recharging Fig. 1 shows how ambient temperature at recharging is related to charging efficiency or as affecting discharge capacity. As seen from the figure, charging at normal temperature is best, and the efficiency decreases as the temperature rises.
