I was just speaking with a surveyor who wants to run differential levels with his total station.
I remember on the old forum, J.D. posted a summation of his practical procedure for doing this. I do not think I was wise enough to save a copy of it and by now I am three or four computers down the road from then anyhow.
Does any Beerlegger have a copy of that? Or maybe Shawn..., you no doubt learned this at the feet of the master or the dumb end of the chain.
I know nothing of what you are asking for but we recently had a good thread on the subject you might glean some useful information from.

Hi Jerry,
I have a hard copy and if no one else has an electronic version, I will scan and post it.

Thanks for the offer to scan and post.
I was hoping to find Shawn's email address in his profile. I read J.D.'s explanation that he posted on the old site and maybe even remember a bit of it.
I thought Shawn might be able to go to the Master himself for an electronic copy.
Do I correctly remember that J.D. wrote and article about his procedure for American Surveyor or some other publication? Maybe I am just showing my age or declining memory retention...
Why would anyone run differential levels with the total station? 🙂
It's not that hard. I remember talking to J.D. in his office about this and I said that we had done it but instead of using the level bubble to level up, after a good colmination of the gun, we used the instrument readings itself to level it (i.e. using the readout as a tilt). It worked but most of the time, we just use trig levels and the method as prescribed by Charlie and Jesse.
Application: Modern Total Stations are Levels, Too
Not J.D. Billings...

Now that you mention it I think he did. I found the hard copy and it has about 30 pages including slides. If I get a chance over the weekend, I will scan it.

Hi Jerry,
As George mentioned, Jesse prepared a very detailed paper. Dad has been doing the same thing for years with methodology very similar (if not exactly the same) as Jesse's, which was taken (if I remember correctly) from Charlie Glover.
With GPS, we haven't run levels in a long time, but before GPS we did levels with total stations almost exclusively - seldom using our auto level. Sometimes we still use the technique for transferring an elevation.
