Trimble S6 angle accuracy

When the TSC2 is connected to the instrument you can check this data I think. Try Instrument > Instrument Settings.
I think it should be possible to do this from the face 2 screen as well by choosing settings (using the face 2 buttons) when the instrument is first switched on.

I do not use a trimble often but the horizontal accuracy could be affected by other things such as are you using nodal prisms for you work. Is the total station colimated between the 2 faces since you bought it second hand.

Well here is a pic of the S3. Partner took the S6 to Zambia last night so cant check right now. But his is the same part of the info. S6 showed 5" horizontal and 5" vertical. EDM is 3mm + 2ppm,which is what I expected. Yes collimation was checked right after we got is (Dec 2015 by local dealer as check before purchase, and again in Feb 2016 at service).

Should I assume its a 5" or is it being limited by software,which is what I'm hoping.

Thanks

The S6 was made in 2", 3", and 5" versions. Based on what you've posted it sounds as though yours is 5".

In my former life I sold a lot of S6s, and every one of them was 3". My thinking was that if someone was going to spend that kind of money it didn't make sense to sell them a 5" gun; conversely, that there wasn't a significant enough difference between the 2" and 3" guns to justify the cost difference. Of course, I offered the options, but everyone apparently agreed with my logic.

And there is a high accuracy version 1", which also has a higher accuracy EDM (with shorter DR range)

Your S6 may be labeled as a 5" instrument, but that may be because it failed to pass a 3" test, maybe even coming in at 3.1". That means little because as you explain you fail to use it to achieve the specified precision. To achieve 3" precision with a 3" instrument requires you to make 2D&2R observations. To tell your least squares program otherwise is wrong.

Some one said one time on the internet that the way they determine the different accuracies is by taking the newly manufactured instrument and bench testing the accuracy. Depending on that test is how they got labeled. Like I said, I read it on the internet. 🙂 Take it for what it is worth, but I can't see a second or two. Jp

I notice that all of the instrument collimation factors are set to zero. I received mine like that when it comes back from the dealers adjustment. I do my own collimation adjustments and I recommend you do the same. I am not convinced that the dealers does not just do a reset.

I see on the image of the DC above that there is "Horizontal Angle Precision" and "Vertical Angle Precision" and I have also seen this in Survey Controller software. Is this just the "rounding" that the angles will be recorded and displayed at, i.e. in the image above 2" for both horiz and vert, and nothing really to do with the instrument accuracy itself?

[USER=7109]@squowse[/USER] by chance it literally (the S3) came from its annual service on the 15th of Aug so thats not yet been checked by us yet.

[USER=236]@Paul in PA[/USER]. Sent a pm. Not being from the US it takes some getting used to you're terms etc. Still trying to figure out what a section or quarter section is, what is a plat?( I understand it be what we call a diagram), what does the stone refer to and how is it different to a monument (stone = property corner marker? Monument = original marker?). Not sure. You also use starnet and carlson ALOT. By us no one uses it. Its TBC,Autocad,maybe Microststion and our processing of networks is done by various local software vendors (our coord system is messed up. South azimuth and increases south-west). Messes CAD work up massuvrly but we've learnt to work around it. So more often than not I will seem like a idiot but I'm fine with that. As long as I learn something.

[USER=11256]@Richard Imrie[/USER] I was hoping for something similar but the answer seems to be that is a 5" gun. I assume that somewhere there might be such an option. Not sure why though

Thanks for all the replies

Hi, Just curious where are you from, I am not from US too. Good to see everyone speak a somewhat common language too. haha

RSAsurv,

The only "Stupid Question" is the one you don't ask?

I spent a lot of time in college asking what others thought were stupid questions, but when you are unsure of something it is difficult to frame the question properly.

BTW to others, we had messaged back and forth regarding terminology shorthand.
