Input the distance, and press [Enter] to enter the interface of
"Offset -Begin". You must aim at point "P0" to measure.After
measuring, press [ENT] to exit the interface to enter the interface of
"Offset-End".
Aim at the end point, and press [ENT] after measuring. The
coordinates of measured points are displayed, as shown in picture
below:
◆If you need the coordinate of 'A0' ,you should set the height
of prism as zero.
◆If you need the coordinate of 'A1' ,you should set the height
of prism as the real height.
8.4 Offset (Plane)
This function is used to measure the point which can't be
measured directly, such as the point on the edge of the plane.
Firstly, you should measure any three points (P1, P2, P3) to
define the measured plane. Then, you can aim at the measuring point
'P0', and the instrument will calculate and display the coordinate of
intersection of the defined plane and the collimation axis. i.e the
coordinate of "P0". Mention that the target height under this mode
must be zero.
