This product is mainly used in the vertical plane of the detected object; 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 size of the gap with a feeler to detect vertical collimator, its value is 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. Use 25g drum sound geological hammer compass before using magnetic declination must be corrected. Because the location of magnetic north and south poles of the south and north poles and geography are not entirely consistent, ie the magnetic meridian is not coincide with the geographical meridian, any point on the Earth's magnetic north to true north direction is inconsistent with that point, the angle between the two directions 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. Desired product orientation is determined relative positional relationship of the measurement laser vertical collimator between the measuring person and the intended product use, that is the intended product was determined azimuth angle (azimuth angle refers to an angle clockwise from the meridian line of the survey). When measuring the relaxation brake screws, make measurements of physical objects pointing laser target plate vertical collimator brand, even if the compass toward the northern end of the desired product, the southern tip of relying on their own, to aim to make the desired product, the objective target plate holes Laser Verticality Miriam dzj200, cover glass filaments, 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 that is still the target product of the measured azimuth . (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).
