8.2.2 Cylindrical Offset Subprogram
Description Determines the coordinates of the centre point of cylindrical objects and their radius.
The horizontal angle to points on both the left and right sides of the object are meas-
ured, and the distance to the object as well.
Access Press Cylindr from the Offset screen.

Field Description
Hz Left Measured horizontal direction to the left side of the object. Using the
verticalhair, aim at the left side of the object, then press HzLeft.
Hz Right Measured horizontal direction to the right side of the object. Using the
verticalhair, aim at the right side of the object, then press HzRight.
∆Hz Deviation angle. Rotate the instrument to aim in the direction of the
centre point of the cylindrical object, such that Hz is zero.
PrismOffset Prism offset distance between the centre of the prism and the surface
of the object to be measured. If the EDM mode is Non-Prism, the value
is set to zero automatically.
