Engineering Test-foot vertical degree is mainly used to detect the object plane; vertical deviation degree (walls, door frames decorative veneer) and other projects, levelness and flatness of any plane. Vertical detection: the detection scale for deployable structure, close up 1 meter long, two meters long to start. Flatness detection: foot side abutting the test surface, the gap size scale detection plug its value that flatness deviation. Level detection: detecting foot side with vial, detectable levels of degrees, use the same general level meter. The main technical parameters (8 paperback) No. Name Range Accuracy 1. Vertical error detection scale 2000 × 55 × 25 ± 14/2000 ± 0.5 2. detect foot diagonal 970 × 22 × 13 1000-2420 (ruler) ± 0.5 3. Multi-function inside and outside the right angle detection scale 200 × 130 ± 7/130 0.5 4. cursor feeler 150 × 15 × 17 1-15 0.5 5. one hundred grid 240 × 115 ×× 3 standard brick 0.5% 6. reel 65 × 65 × 20 15m 7. mirror 110 × 65 × 15 8. drum sound geological hammer 25g use compass north and south poles because of the position of the geomagnetic North and South poles and geography are not entirely consistent, ie the magnetic meridian and geographical meridian does not coincide with the Earth at any point to true north and magnetic north of the point is inconsistent, the angle between the two directions is called magnetic declination. East of the northern tip of the needle at a point on the earth somewhat north direction is called the East side, west side, said the West are somewhat biased. East bias is (+) Western bias of (-). Declination everywhere on Earth are calculated periodically if known declination of a point, the relationship is a test line of magnetic azimuth A magnetic and true north azimuth A is A equals A subtraction magnetic declination. This principle can be applied magnetic declination correction scale can spiral rotating compass when corrected, so that the level or turn the dial to the left to the right (east declination is biased to the right, then left the West migraine) that compass north and south between the chassis and the horizontal scale line connection dial 0--180 degree angle equal magnetic declination. After reading the measurement correction on the true azimuth. Azimuth measurement target compound is the desired product and the determination of the relative positional relationship between the measuring person, that is, the desired product was measured azimuth (azimuth angle refers to an angle clockwise from the meridian line of the survey). When measuring the relaxation brake screws, so the objective target plate measurement point on, if the compass toward the northern end of the target product laser marking device mapping equipment, the southern tip of relying on their own, to aim to make the desired product, the objective target plate holes, cover filaments of glass, for purposes such as target plate holes even in a straight line, while the chassis is centered bubble vial, to be referred to the degree of the compass needle still is the measurement of the azimuth of the target product. (If the pointer is still not the moment when the needle swings readable half the minimum degree at the same time also measure other elements of reading). Laser vertical collimator 1. placement, alignment, leveling the tripod placed on the station, the instrument installed in the base of the tripod center hole to force the locking base clamp knob, the instrument stable. Adjust the height of the tripod, the telescope eyepiece roughly human eye contour. Open to point the laser switch, adjust the hand wheel on the spot focusing the laser is focused on the measurement site. Adjustable tripod, so the bubble is centered round blisters. Turn the instrument alidade so vial with screw connection between any two feet parallel, the same amount in the opposite direction rotating spiral two feet vertical collimator laser surveying instruments, the bubble is centered. The instrument alidade rotated 90 ?, swirling spiral third leg, the bubble is centered. Using the above method repeatedly adjusted until the instrument is rotated to any position deviation does not exceed the maximum bubble fourth grid value. The instrument alidade rotates 180? Inspection of the circumstances, if any deviation, loosen the center of the spiral, the entire instrument in the frame head pan, until the laser spot and precise alignment of the station. Turn the alidade, confirm that the instrument is rotated to any position, long level is centered, if deviation from total station surveying instruments, repeat the above steps. Confirmation, and after leveling is completed, will point the laser turned off to save electricity. 2. Place the grid laser sighting target at the target. Turn the telescope eyepiece reticle crosshairs makes clear, then turn the focusing knob in the laser target reticle clear imaging, and try to eliminate parallax, that is, when the observer moves slightly sight, there can be between the reticle and the target significantly offset. Otherwise, you should continue to ignore the above steps until the poor. 3. A. upward vertical collimator optics vertical quasi If the instrument has been calibrated, when the instrument is leveled, the collimation axis coaxial with the vertical axis error ≤5 °, can be used as vertical alignment, a prospective observational ensure vertical accuracy. However, in order to improve the vertical quasi-precision instrument should be rotated 180 ?, alidade get a second observation through a telescope, whichever number (midpoint) of the measured values.
