modern electronic digital theodolites contain circular encoders that sense the rotations of the spindles and the telescope,convert these rotations into horizontal and vertical (or zenith) angles electronically,and display the value of the angles on liquid crystal displays (LCDs) or light-emitting diode displays (LEDs).These readouts can be recorded in a conventional field book or can be stored in a data coolector or some other printout or computation.The instrument contains a pendulum compensator or some other provision for indexing the vertical circle reading to an absolute vertical direction.The circle can be set to zero reading by a simple press of a button or initialized to any value on the instrument.
