（6）Target prism is sighted, presses measurement of coordinates key, total powerstation starts ranging and calculates the three-dimensional coordinate of display measuring point.
As can be seen here, total powerstation instrument height is very important underlying parameter, and the precision of instrument height is adjusted the distance with coordinate etc.
The measurement accuracy of fundamental influences very big.
The measuring method of existing instrument height mainly has the following two kinds.
（1）Steel tape mensuration
Most traditional instrument height measuring method.Instrument height is vertical range of the measurement control point to centre, is directly surveyed
Amount is not because being flat relation of plane, and absolute being error, steel tape measurement error is larger in addition.
（3）Laser optical method
The amount of laser light point function having using instrument itself measures, although laser measurement precision is all higher than above two side
Method, but because hot spot is beaten inside crosshair rather than datum mark peak, systematic error is brought, overall measurement accuracy is limited
System.
The measurement accuracy of above measuring method is grade, the inapplicable occasion for needing fine instrument high parameter.
