Vertical Scanner Configuration (contd)
F: Scanner beam resolution − 3/4 in. or 3/8 in. This presets the noise
compensation to 10% of a single beam voltage. This value varies with the
scanner length and resolution.
A 72 inch scanner:
S at 3/4 in. has 96 beams with 0.1 volt per beam.
S at 3/8 in. has 192 beams with 0.052 volt per beam.
Z: Zero offset override − for noise and ambient signal compensation. Refer
to Setting the Zero Offset on page 4-32 for a detailed explanation.

Vertical Offset (Reciprocators Only)
Use the vertical offset for reciprocators only. For vertical (up/down)
positioners, set the vertical offset to 0.
See Figure 4-27. The Vertical Offset should be positive if the 0 channel of
the scanner (topmost beam) is below the gun 0 position. The gun 0 position
is the end of the gun travel.
For example, if the offset is 8 in. and the top of a part breaks the 0 channel
then moving the gun down by 8 in. from the gun 0 position should align the
gun with the top of the part. If the part is 20 in. long, then an 8 in. offset
means that the gun must be moved down 28 in. to be aligned with the
bottom of the part.
The Vertical Offset should be negative if the 0 channel of the scanner
(topmost beam) is above the gun 0 position. This causes the scanner area
above the gun 0 position to be ignored and reduces the length of the
scanner by the offset.
