• If needed, the values recorded with set_trigger and backward-transformed
transferred to the PC by get_transform_offset can additionally be untransformed
transferred to the PC by get_waveform.
• If backward transformation of z position values is requested ( Code Bit #0 = 1), but only
a 2D correction table has been assigned at the timepoint of the prior successful call to
upload_transform, then the offsets to the focal length and z coordinates are
initialized with 0 and the values A, B, C with are initialized 0, 1, 0 (1-to-1 backward
transformation).
• For backward transformation of xy position values ( Code Bit #0 = 0), only the z = 0
plane are transformed. xy stretching and Z defocus due to z deviations (particularly
with non-F-Theta systems) are not taken into account.
• PCI transmission errors generate the get_last_error return code RTC6_SEND_ERROR .
