I've been using Trimble Survey Controller 12.5 on a TSC2 with an old Zephyr/5700/5800/Trimark III setup and started setting that DC up to use with my Leica TCA1101+ total station today.  I have a new…Read more →

OPUS problems (or is it me?)

Started this discussion. Last reply by Dave Drahn Jun 2, 2016. 12 Replies

I set up my Zephyr Geodetic and 5700 receiver to collect fast static and let it sit for a couple hours - actually have done it 3 times now.  I've got the v2.32 fw on the receiver so it collects…Read more →

Very general question on rectifying a boundary that doesn't fit found monuments

I don't need to do this and I have some text that probably describes best practices in these cases, but just wondering about found monuments vs record corners.  It seems like there would be a number…Read more →

"If you're 4" off plumb measuring a 5.50' high target, the slant measurement would be 5.51.  I go with subtracting 0.01' at the most."

"Thanks.  I think that does help.  I'm just a little concerned that Trimble may recognize that when setting up a Leica instrument in their DC software, that you would want to input the Leica Constant... That's less likely, though.…"

"I just went through a similar exercise with our crews and equipment.We run an old Geodimeter 650 with 360 mini prism (6mm prism constant) and a Leica TPS1201 with a Lieca 360 passive tracking prism. Additionally, we use flat, SECO prisms (0 and 30…"

Prism offset, leica, trimble

I've been using Trimble Survey Controller 12.5 on a TSC2 with an old Zephyr/5700/5800/Trimark III setup and started setting that DC up to use with my Leica TCA1101+ total station today.  I have a new Trimble 360 prism with a +2mm offset.Straightforward, right?I'm confused, though, about the prism settings in the DC.  I set the instrument to my Leica and it asks for the prism offset, from what I understand, Leica calls a 0 offset "34.4mm", so would my Trimble 360 (+2mm) be set to 36.4?  It's a…See More

Dave Drahn replied to Killivien Sithole's discussion Setting out inclined columns
"At least for me, you'll have to clarify the problem a little better.  A dwg would be best, but I'm not positive what you mean by "setting out 8m at 6 deg inclination"and even less sure what a 6.4m box looks like inrelation…"
