Leica 1200 system
This is what I fear in the Leica 1200 system: It imports data from irrelevant files, and files I have deleted will return.
I’ve learned to have only one file in the rover at a time, so it won’t import strange points, but it still manages to find them somehow. I open a new file called Payson and import my pre-calculated points, all in the 1-23 range. Suddenly there is also a point 4223. The import file has no such point. Just in case, I look in the calibration files which I cleared out the day before. There are two old ones still there. I clear them out. After doing all of the GPS work, very carefully I might point out, I switch to the rover. First setup the difference in distance to the backsight is great, but the elevation is off by a tenth. I do the setup over and again carefully measure up and shoot. Still off by a tenth. I look in the calibration files and there are two old ones, the same ones I cleared out both this morning and yesterday. I realize that the system is somehow warping my elevations to try to match something in Tucson, miles away. I clear out the two old calibration files, again.
This morning I use the rover to look at the files, and one of the old calibration files is back. Aaaaarrrrgh.
