2. Adjust the parallelism with respect to the machine guide of the scale rear while measuring the scale
rear with a dial gauge. Tighten the set screws.
<Measurement method>
Measure at two points where the measurement distance is as wide as possible and at the same distance
from the right and left scale ends. If using a scale with intermediate foot plate, be sure to also measure the
intermediate foot plate.
3. Insert the supplied spacer (t = 1.0 mm) in the space between the scale and the scale head, and then
adjust the scale head position while bringing the scale head into contact with the scale.
Check that the gap at the two ends is 1 mm using a spacer (with a 1.0 mm thickness).
