Theodolite Calibration

Theodolites are instruments designed to measure both horizontal and vertical angles with precision. Primarily used for surveying and in other large scale applications, they typically feature a telescope mounted between two perpendicular arms on a rotating axis which allows for extremely precise measurement, usually in terms of arcseconds. Optical tooling equipment like theodolites  are necessary for surveyors to provide precise angle calculations.

With surveying teams relying on these devices to create foundations, roadways, and other large scale engineering projects, it’s important to have this equipment calibrated on a regular basis to ensure quality in projects and even safety. Cross offers NIST-traceable calibration services for the following devices among others:

  • Optical and electronic theodolites
  • Autolevels
  • Basic and jig transits

How do I know if my optical tooling equipment needs to be calibrated?

The frustrating thing is you don’t!  You can’t tell by looking at it if it’s out of calibration or not.  The circumstances when you should look into calibration include when your equipment is:

  • Bumped or dropped
  • Damaged
  • Not used for a long period of time
  • Used very heavily

Because it may not be obvious that your total station or autolevel isn’t measuring correctly, it’s important to have it calibrated regularly. In the event of a disagreement over a measurement, a certificate of calibration can attest to the accuracy of your equipment.

Cross Optical Instrument Calibration

With convenient mail-in service and quick turn-around times, the optical instrument calibration at Cross can provide trust and peace of mind in your measurements without slowing down your operation.  The calibrations we can perform include:

  • Bearing runout, horizontal and vertical
  • Collimation, horizontal and vertical
  • Optical/mechanical centering
  • Line-of-sight straightness
  • Line-of-sight concentricity and many, many more.
