How to check a Total Station. A Total Station should be checked at least once a month or before any precise work is to be carried out.. The checks on a Total Station should comprise of a five-point check carried out in the following order.

Capability of a Total Station. Microprocessor unit in total station processes the data collected to compute: Average of multiple angles measured. Average of multiple distance measured. Horizontal distance. Distance between any two points. Elevation of objects and. All the three coordinates of the observed points.

~Important). The battery has not been charged at the factory. Please charge the battery fully before using.-:mportant:; Tribrach clamp ~ locking screw When the new SET B is shipped, the tribrach clamp is fixed with

can measure using a theodolite or a total station in everyday surveying work is the so called mean direction (MD) which is the angle measured clockwise from the 0 mark of the instrument’s horizontal circle to the direction of the unknown point. Looking at Fig. 1, we can see that there is a constant difference between the

Advantages of Total Stations Total stations are known for their accuracy, ease of use, and the ability to quickly collect information. With a total station, multiple surveys can be performed from one setup location, and it is easy to simultaneously take distance and horizontal measurements and calculate project coordinates (x, y, and z or northing, easting, and elevation).

Preparing to measure. Setting up the total station over a ground point. 1.Place the tripod approxi- mately over the ground point. 2.Inspect the tripod from various sides and correct its position so that the tripod plate is roughly horizontal and above the ground point (illustration, top left).

Four models are available with different angle accuracy grades ranging from one to five inches. ... and will never go back to using a manual total station.” ... “A magnetic-drive servo on the ...

Theodolites are essential surveying instruments used for the measurement of horizontal and vertical angles. The latest theodolites have infrared distance measuring devices, for which regular infrared inspection is essential. Leveling systems are fitted for accurate installation of theodolites. Theodolites are similar to total stations, except that the total stations are used when the distances ...

Task 2: Horizontal Angle measurements using close-the horizon-method 1. Setup and level the total station at the point assigned to your group 2. Point the total station to the point that marks the left hand side of the angle. Lock the motion and set zero on the instrument.

Vertical Angles and Elevations. When using total stations to measure precise elevations, the adjustment of the electronic tilt sensor and the reticule of the telescope becomes very important. An easy way to check the adjustment of these components is to set a baseline.

Sep 27, 2014 · Total Station Basics using the Nikon Nivo Last year, I had the great experience of going to Bhutan to conduct a week-long workshop on mapping using Total Stations and GPS. I brought with me a Nikon Nivo 3.M and a mini-prism.

How to check a Total Station. A Total Station should be checked at least once a month or before any precise work is to be carried out.. The checks on a Total Station should comprise of a five-point check carried out in the following order.

An angle measured 6 times by an observer with a total station having a DIN18273 value of ±5". What is the ... A HORIZONTAL ANGLE Assume a rectangular parcel, with ...

Total Station Vertical and Horizontal field check This quick and easy check will allow you to check and verify that the Vertical and Horizontal angles are within the manufactures specifications. Set up your Total Station and a target at least 100 meter apart. It will work better if can use a

Theodolite and Total Station, as only civil engineers or students would know, are land surveying instruments used to deduce information about the plot under consideration for construction (buildings, bridges, roads, highways, dams, etc.)

1. Sight BS at station 114, zero horizontal circle; most tachometers have a zero-set button. 2. Enter code 20 (BS), Figure 2. 3. Measure and enter the height of the reflector (HR). 4. Press the appropriate measurement buttons: distance, horizontal angle, and vertical angle. Press "record" button after each measurement.

Advanced Angle Measurement System All PS series Total Stations features advanced absolute encoders for long-term reliability in all work conditions. Dual-axis compensation ensures accurate leveling even on rough terrain. Motion clamp and tangent screw ensure stable angle measurement. PS-101 and PS-102 are equipped with

A Theodolite is a measuring instrument used to measure the horizontal and vertical angles. Theodolite is more precise than magnetic compass. Magnetic compass measures the angle up to as accuracy of 30’. Anyhow a vernier theodolite measures the angles up to and accuracy of 10’’, 20”. It is of either transit or non-transit type.

The MapStar TruAngle, like its predecessor - the MapStar Angle Encoder (MSAE), precisely calculates a turned horizontal angle that can be referenced to any desired point or direction. When integrated with an LTI laser, you can capture X, Y and Z coordinates for complete 3D mapping and surface modeling.

The MapStar TruAngle, like its predecessor - the MapStar Angle Encoder (MSAE), precisely calculates a turned horizontal angle that can be referenced to any desired point or direction. When integrated with an LTI laser, you can capture X, Y and Z coordinates for complete 3D mapping and surface modeling. An angle represents the difference between two directions. Under ideal conditions, the horizontal angle between the two directions leading to the points P1 and P2 is independent of the height difference between those points, provided the telescope always moves in a strictly vertical plane when tilted,...

In the previous example, it was determined that the deflection angle for station 0 + 200 was 0o 14' 01"; it follows that 0 + 200 could be located by placing a stake on the transit line at 0'14' and at a distance of 3.262 m (200 - 196.738) from the BC. Station 0 + 220 could be located by placing a stake on the transit line at 1o 39' 58"and at a
