6 Reference point signal single-amplitude check and
adjustment
Move the slider part in the right direction with respect to the
scale part, and pass through the reference point.
When moving the slider head, check that the reference point
top-side single amplitude C (Fig. 4-7) is within the specified
value.
If it is not within the specified value, adjust the amplitude so
that the reference point top-side single amplitude C is set at
the specified value.
Specified reference point value of single amplitude =
1.0 V ±0.04 V

7 Reference point signal DC level check and adjustment
Move the scale part or slider part to a position having no
reference point.
When moving the slider head, check that the reference point
signal DC level c (Fig. 4-8) is within the specified value.
If it is not within the specified value, adjust the DC level so
that the reference point signal DC level c is set at the
specified value.
