I recently had the above mentioned total station sent in for cleaning and calibration. When traversing, I usually turn 2 to 3 sets of angles to the next control point in repetition mode in survey pro. Before I had the instrument serviced, I very rarely ever had a bust in my tolerances. Since the service, I have a lot of trouble meeting my tolerances, 20' horizontal and 20' vertical. Is this something as simple as collimating the instrument or did the dealership mess my instrument up? Any insight would be appreciated.?ÿ

Make sure you do not have a loose tribach connection, leg of the instrument or tripod leg. As the sun has been warm here, melting frost may be the culprate

Agreed. To find out for sure if you have a problem, perform your normal sets routine with another instrument, then swap it out for yours and see how it stacks up.

While the instrument was in for service, I purchased a new set of Dutch Hill Legs and have used them since I got the instrument back. Everything on the legs seems to be tight. They have the aluminum base plate. I will try my old set of legs for a test.

I'll never run out of stupid questions but, when you say 20'(minutes), did you mean 20'(minutes), or 20"(seconds) .. I know it's a ridiculous question.

Does the instrument have a function to collimate it yourself? ?ÿIt is usually a simple thing having you take observations in face 1 and face 2.

The instrument does have a function to collimate itself. I called the dealer today that serviced the instrument. One of the service technicians spoke to me and he told me to try the same thing, collimate it. I was looking at the manual I received when I purchased the instrument on how to do it. The technician walked me through the process of how to do it. So, I am going to try and collimate it in the next day or so. He told me that if that doesn't fix it that I will need to bring it in for them to look at. Also, he told me that for every change in temperature of 18 degrees that it should be collimmated.?ÿ
