| How do I stake out a coordinate using this instrument? |
| |
| Turn the instrument on and index vertically and horizontally. Enter into page 3 of the main menu and select the F4 option. First of all, you must set your station (Stn) and backsight (H angle). Using the rocker panel, select the option for and key in the coordinate location (N-Northing, E-Easting, Z-Elevation) where you want to start including your instrument height and target height (if using elevations). You may also want to select the station from a list of uploaded or keyed in coordinates. You can do this by selecting the softkey. Here, you will see a point list that you can choose from. Hit , when you are satisfied with the data populated in the window.
Now, you must set your Horizontal angle (backsight) so that you will be rotated properly to your project area. More than likely, you will want to use the option here. It will let you key in a Northing, Easting, Elevation or use the softkey to select from a point list. When satisfied with the information in the backsight screen, hit the key. Now, it should show you a screen that says "Take BS". Sight on your backsight point and then hit the key. Your instrument should now be oriented to your working project area. If all you wanted to do was "0 set" on a point, then you can turn to a point and select the "0 Set" softkey from page1 of the main menu and you would bypass the "Backsight" procedure.
Now, you are ready to key in your data to stake out. From the S-O screen, you need to select the option. You may either key in an angle and distance on this screen or select a coordinate from a list. If you select the softkey, then you can either key the coordinates in as you go (NEZ) or hit the key and select from a point list. Once this data is complete, then hit the key.
When you hit the key, you will be presented with a real-time stakeout screen where you are required to turn an angle and shoot a distance to navigate your target to the point. You will want to turn the total station so that the dHA field is zeroed out by angle and lock the horizontal tangent screw. (i.e. turn the dHA to 0 degrees). This will ensure that you are "on line" and you will need to navigate the target to be in your line of sight. Now, you are ready to start taking readings so that you will be able to move the target in and out to locate the point. Hit the softkey to initiate a reading. After you have done this, you will see a field at the top that shows you "S-O S". This is the field that tells you how far you need to go in or out (from the total station). If it is showing a negative value, then that means that you need to move your target away from the total station the distance that it is telling you while still in the line of sight of instrument. If you are getting a positive value, that means you need to bring the target in towards the total station at the distance given on the line. Once you have brought this value to within an acceptable tolerance ".0xx" on the distance, you have staked your point. Now, you may key in new for other coordinates or parameters to stakeout. |
