As the title says where can I find dimensions like the exact height from tribrach.
Perhaps you can find your answer here in the attached pdf.
@lurker Thanks Lukas but for some reason I can not downloaded. Can you send it somehow?
I printed it with my own pdf printer maybe this will work. I'm not sure how to send it otherwise. I'd email it if you post your email address. I'll also look into your profile and see if I can find something in there to send it to you.
I uploaded a copy to my webspace: Leica LGS Height Reference Guide
Just google "LGS Height Reference Guide" and you will have it.
Where did you find that sheet? Over the years I've pieced together my own version from info derived from instrument manuals. I'm going to have to remeasure everything since I held 50.5 mm from the center of glass to ARP, that damn silly 0.2 mm is going to bite me. One nice thing that the sheet does not mention is that the instrument axis is at the same 196.2 mm.
Also, be careful with the tape hook hole on the 121. I have a couple that are drilled 10 mm to high and I'm going to assume they are not knockoffs since I picked them up from Leica.
I didn't pay too much attention to the exact source but it was found with a google search.
