How to Set the Azimuth Angle on a Topcon Total Station (AMTS)?

Setting the Azimuth Angle – Topcon (AMTS) Total Station

Today we are going to be taking a look at setting the azimuth angle on your Topcon total station.

1. The first thing that we are going to want to do is to aim our total station at the prism that we are going to use the center angle.
2. Once we do that, once we aim at that prism, we will see that the sighting collimator, the white triangle, is visible when we look straight down the barrel there.
3. Now we are going to take a couple steps back from the total station so that the collimator, the white triangle, is still going to be visible right down the center there. And you can just barely make that out, but that white triangle is still visible when we put the automated total station sighting right over the prism.
4. Now that we are perfectly in line with the automated total station still, we are going to take out our compass. And if we take a measurement on our compass of the current facing of that prism, we get a measurement of 126 degrees.
5. Subtract the current magnetic declination of 13 degrees and we get 113 degrees for our current horizontal angle.
6. So the next thing that we are going to want to do is now we just need to set the horizontal circle of the automated total station to that angle.
7. So, to do that, to go back to the main menu, we are going to hit menu, we are going to hit coordinate, hit occupy setup.
8. Now for the coordinate that we use, we are going to choose, in this case, an arbitrary coordinate, but we could use a specific one if we want to. Here, we are just going to be orienting the grid to the true northeast.]
9. We are not going to put in the true coordinates.
10. Now the current angle is 24 degrees, is the current horizontal angle. We want to set that to 113.
11. So we are just going to key in 113. Oh, we hit an extra number there. 113.
12. We are going to hit search to make sure our total station is locked on the dead center of that prism. And then we will hit okay.
13. And now we have set our current angle to 113 degrees. You can go ahead and hit measure and we can measure the relative coordinate of that prism from our total station (AMTS) based on this point that we said we are occupying in a very close to true northeast grid.

And there is our result!
