A tacheometer is a type of theodolite used for rapid measurements. It determines the distance to the target electronically or electro-optically. Tacheometry is a system of rapid surveying that does not use chain or tape. There are times when measuring with a theodolite and measuring tape can be dangerous or impossible.
A theodolite is an older surveying tool. Those were just precision optical devices used to compute angles between known fixed points, and they required using trigonometry to get the final values. However, there are modern versions of theodolites called Total Stations that are more convenient to use than even a tacheometer. These will cost you about $50,000 a piece or so.
Please note that the question asks about a tacheometer (or tachymeter) which is a surveying tool, not a tachometer which measures engine speed.
Tacheometer is a somewhat obsolescent term for a type of distance meter or range finder, somewhat similar to a theodolite as it is precisely leveled and it used from a tripod. Tachometer ( to measure speed) is the device that indicates the shaft speed of a motor vehicle engine, and is always calibrated in Revolutions per minute- or RPM. As I mis-thought in the drummer boy song- Then he nudged her ( sound effects) followed by the R.P.M. kept time! ( sounds like a song like the Hot Rod Lincoln!

What is the type of theodolite?
Transit and non-transit theodolite.
What unit does a theodolite measure?
A theodolite is used to measure angles of a plane. This can be both vertical or horizontal, and it is used with high precision.
What is the least count of a theodolite?
20 degree
What pccupation would a person have who used theodolite?
surveyors
Functions of indvidual parts of the theodolite?

What are the differences between a theodolite and a tacheometre?
when theodolite is fixed with analytic lens then it is called tachometer, without the analytic lens the instrument would be called as constant zero.
What is the difference between theodolite and tachometer?
A theodolite is a survey instrument. A tachometer tells you how many Revs per minute an engine is turning.
What is the difference in between levelling machine and theodolite?
Dumpty level can be used only for vertical measurements while a theodolite functions in both horizontal and vertical measurements.
What is the index error in theodolite?
Half of the difference between the two positions is called the "index error".
What is the difference between thedolite and total station?
A theodolite is a surveying instrument used to measure horizontal and vertical angles. It requires a separate instrument to measure distances. A total station is a surveying instrument that combines the functions of a theodolite and distance measuring device, allowing for simultaneous measurement of angles and distances.
What is the difference between compass traversing and theodolite traversing?
Compass traversing uses a magnetic compass to determine directions, while theodolite traversing involves the use of a theodolite, which is a more precise instrument for measuring horizontal and vertical angles. Theodolite traversing provides more accurate results compared to compass traversing.
What is the diffrence between thedolite and total station?
A theodolite is a surveying instrument used for measuring horizontal and vertical angles, typically with a rotating telescope. A total station combines the functionality of a theodolite with an electronic distance measurement (EDM) device to measure angles and distances simultaneously. Total stations are more advanced and versatile than theodolites.
What are the advantages of an anallactic lens used in tacheometer?
An anallactic lens in a tacheometer allows for accurate measurements by compensating for the tilt of the instrument. This results in precise readings regardless of the vertical inclination of the tacheometer. It simplifies the leveling process and helps maintain accuracy in surveying tasks.
Who is the father of Theodolite?

What is the difference between a transit and a theodolite?
They are the same - they are precision instruments having telescopic sights for establishing horizontal and sometimes vertical angles . In the US and Canada they are called Transit Levels, in the UK Theodolites.
