Working on a big site at the moment where the secondary controls (retros) are 100-200 meters away so I took my kit to the annual calibration early to make sure all good. When got the kit back I did the checks and I was not happy... The way I did the check is, that I saved a point on a fixed point/retro, then turned the TS (total station) facing me, then turned the optical vertically 180degrees (upside down), went onto the saved point and layout the point and I got 12-14mm error on 120meters, did the same on another point 70meters away and I got 5mm error. Got the other engineer on site to do the same with his ICR55 (5"!!!) kit and he only got 5mm error on the same 120meters.
I am sure the calibration could be better on my kit, I am getting in touch with the company now who did it, but I thought I ask here if anyone experienced similar before? Also, anyone know about any accuracy the calibration must be done within?
