4.3.2.4. Control Measurements
 
If control measurements are to be made with a total station, this can be performed from any particular station by measuring the starting point and the end point of the line segment. The control measurement is then derived from the bearings and distances. 
 
The tachymetric measurement of control surveys is called up through the menu function Calculate > Basic Tasks > Control Measurement. The first measurement takes place towards the starting point of the segment. By clicking the <Meas.> button, it can be repeated as often as desired before the measured values are registered by means of the <Save> button. For the 2nd measurement the end point is collimated; this point is simultaneously the starting point of the second control survey. If the first measuring point is collimated once again, a ring and area calculation occurs automatically. The >> button activates the control functions in the case of automatic tachymeters.
 
You can quit the menu with <X>.
