Adjusting the Pen Position
● Overview
This is an adjustment of the pen position to make the recording position 0 to 180 mm.
Each pen is adjusted individually. The adjustment is performed when the recording
accuracy is outside the criterion, or when internal components have been replaced.
Conditions
• Use a standard pen (or equivalent).
* A “standard pen” is one whose tip does not fluctuate more than ±0.1 mm.
• The adjustment matches the Zero position to the 0% position of the z-fold chart
paper.
• It also aligns the Full position from the 0% of the z-fold chart paper to the 180 mm
position.
• For measurement, use a Glass scale (or equivalent).
● Criterion
Adjustment criterion: within ±0.1 mm
● Procedure
1. Install the pen into the pen arm.
2. Press the MENU and CH UP keys while turning ON the power. Menu = A/D
