The two-peg test is used to make sure the line of sight provides an accurate reading and determine how much of an adjustment is necessary. How do you know if a transit is accurate?įor a leveling instrument to be accurate, the telescope line of sight must be parallel to the axis of the bubble tube. The transit level can be adjusted vertically at 45degree, but the builders level cannot be adjusted vertically. In contrast, the builder’s level can move horizontally in a complete circle.
What can a transit level do that a builders level Cannot?Ī transit level, when it is locked into place, it can only tilt vertically and has a limited range of mobility. While the purpose of the two is similar, as a general rule a theodolite is more accurate than a transit. The transit and theodolite are used by the surveyor to measure both horizontal and vertical angles. It not only can establish a level line, but also a plumb line when looking through the scope or sight. What is the difference between a level and a transit, you might ask? A level basically does just one thing – it establishes a level line when set up on a tripod. What is the difference between a transit and a laser level? Theodolites tend to have a more precise reading and provide greater accuracy in measuring angles than transits do. Theodolites use enclosed graduated circles and angular readings are taken using an internal magnifying optical system. Transits use vernier scales and external graduated metal circles for angular readings.
What is the difference between transit and theodolite? The transit itself is leveled using the spirit level. It is calibrated to indicate not only true horizontal but also to provide a reading of the angle of inclination in degrees, minutes, and seconds. This differs from the builder’s level which can move horizontally in a complete circle.Ī transit level is a precision instrument. A transit level, when not locked into place, can tilt only vertically and has a very limited range of mobility. There is one main difference between a transit level and a builder’s level. What is the difference between a transit and a level? Transit Definition = A surveying instrument used to measure horizontal and vertical angles.
