Hi all,
We just had to send our Nikon Total Station in for repairs and attached you can find the repair details. What do they mean by "The tilt sensor was turned off"? I understand that this means the leveling for the instrument was off and that's what was causing the problem, but where is the tilt sensor located? I couldn't find anything about it in the Nikon DTM-332 Instruction Manual.
Thanks in advance.
Howdy Evan M, welcome
I would contact the shop &tech that worked on the gun and find out
Never hurts to get an understanding with those that keep your tools on the job

True, that'd probably be a good idea. But you don't happen to know what they mean by tilt sensor do you?
I'm not familiar with Nikon guns, but it sounds like you may have been operating the instrument with the compensator(s) disabled.

That's exactly what I was thinking.
Actually it says "TILL" sensor. But I assume they are referring to the H& V compensator(s) were disabled.

I think that was just a spelling error on their end. Earlier in the detail they used tilt.
I'd always wondered if they use those two terms interchangeably. A tilt sensor to me means the instrument won't operate past a certain misalignment.
A tilt compensator, again to me, means the instrument tracks the misalignment of the axis and provides the corrections to measured angles.

Tilt sensor is an electronic tool and apart of the software that allows the use of the compensators on your instrument that works like an extremely sensitive electronic level bubble.
My Sokkia Set 330R has TILT and can be selected to be on the multiple menu pages that operate from the function keys.
The bulls eye bubble gets close to level and the TILT function takes over from there to obtain as near as level that your instrument is capable of.
When functioning correctly, it will allow the instrument to obtain better accuracy in the lower second ranges of your closures that allows greater repeat ability.
Tilt sensor and compensator are somewhat interchangeable terms. The tilt sensor detects the tilt in each axis (on a gun with dual axis compensation, which pretty much any survey grade gun has these days) and computes the applicable angular corrections; it also prevents the instrument from working beyond a certain tilt range, typically five or six minutes. However, on most if not all instruments it's possible to disable the compensator. This is desireable under certain conditions, mainly when set up on an unstable platform.
I understand it's somewhat axiomatic that an intrument with a tilt compensator would have a tilt sensor. I'm not sure this was always the case and can remember old Topcons we used that wouldn't measure once it was too far out of tilt. Whether they had compensators or not, I don't know.
The old Topcons had single axis compensation - I'm pretty sure that's what they had on the GTS-3 series. Sokkia used to make a big deal out of their "famous" dual axis compensator... The original SET instruments were workhorses (albeit slow ones) but the later ones went out of calibration if you breathed on them.
