Hi-Target ZTS-320 Series - Column Offset Mode

47
8.5 Column Offset Mode
Firstly, you should measure the azimuth angle and
coordinate of „P1‟ on the cylinder under this mode. Then calculate
the horizontal distance, azimuth angle and coordinate of the
cylinder by measuring the surface points of tangency P2 and P3.
The average value of P2 and P3 is the azimuth angle of the
cylinder.
Enter „5.Offset(column)‟ from the offset menu.
Press „Meas‟->
◆If you need the coordinate of „A0‟ ,you should set the
height of prism to zero.
◆If you need the coordinate of „A1‟, you should set the
height of prism to the real height.
Then press „Meas‟ to start measurement. Press „ENT‟ to
accept the measurement result and enter the interface of
„Offset(column)—Left edge‟
