Linearity Adjustment Procedures
1. Connect the each clips of LISTA cable to test points.
2. Set the adjustment mode. (Refer to [LISTA Adjustment Modes] on the “Table of Test Point”.)
3. Playback the LISTA Alignment Tape.
4. Select the item “<2> Linearity Measurement” on the LISTA main menu, and then linearity waveform appeared
on the screen.
5. When the waveform as shown below figure is displayed on the screen, press the ”BS (Back Space)” key for
display the waveform positioned at the center of the scale on screen. Adjust S1 and T1 post height by using
the post driver so that the linearity waveform is become flat as possible, and it should be within specification.
♦ Adjust linearity waveform in the red dot line on the screen.
6. After finish the Linearity Adjustment, measure the numerical value of linearity and waving.
Adjust linearity
into this area
POINT :
The part of left side of waveform (entrance side) is adjusted by height of S1 post and part of right side of
waveform (exit side) is adjusted by height of T1 post.
Lower part of above waveform of figure is displayed lead of Cylinder.
When the post driver is remove from upper part of post, linearity waveform is changed.
After finish this adjustment, eject the tape and insert the tape again for confirm the shape of linearity waveform
does not changed.
