Sorry, a little late back to the party.
Imaudigger, All the books I have are for a 4400, which have been dead on so far, but the machine indicates it is an ATS.
Andy, I am aware that the machine converts the SD and VA to obtain HD, but my question has to do with the true centerline of the RMT when the RMT is mounted perfectly vertical on the prism pole and the gun shoots it at an angle. Now, I realize a little angle probably won't affect much, but how much angle is reasonable before you start having problems? or is it safe to assume that if the gun will return a reading, the prism is fine?
Example, you take a shot at the top of a building and you do not aim the RMT at the gun, you just hold it perfectly plumb with the world. Does this affect the accuracy of the SD thus the HD as well? Or are prisms just made to return about the same values regardless of odd angles, which are obvious to the trade?
FYI, we do have a calibrated baseline in our area with several pins so that might be a way to quickly determine how close we are.
As to measuring a line, my concern is calibrating the gun based on what a roll-a-tape might read. I realize we might be splitting hairs there but if that tape is not on a really nice level surface, this might not be the best approach?
Bob, what's the serial number of the machine?
Chris, I will send that to you.
I have a software manual for the "Geodimeter Software System 400"
I don't know how that relates to the 4400.
