102 Pulse Laser Station NPL-302 Series Instruction Manual
Once the plane is defined, the calculated a and
b values are updated as you move the
telescope. No distance measurement is
required.
a Distance between P1 and the point that
is perpendicular to the target point
along the P1-P2 line
b Length of the perpendicular line from the target point to the P1-P2 line
Using [DSP] to switch between display screens

If the plane is defined by two points (by
selecting 2Pt), the vertical plane is the
same as the plane used in the V-Pln
function, but the indicating factors are Sta
and dZ, not a and b. For more information,
see Measuring distance and offset values
on the vertical plane, page 99.
