Step Action
2. Install the End Caps on the Mounting Surface:
1. Remove the adhesive backing from end cap.
2. Place the end cap on the top of the scale and epoxy so that the end of the scale is in the
middle of the end cap.
3. Press down lightly to ensure adhesion and let cure for 24 hours.
7.0 Final Cleaning, Inspection, and Cure Time
Before using the encoder for servo control, clean the scale, index marker, and limit markers using
alcohol or acetone and a lint-free cotton cloth or swab. Finally, inspect the scale's surface for
scratches, adhesive spots or smears in the measuring length.
For tape scales, a cure time of 12 hours is required for the scale's pressure-sensitive adhesive to
achieve the best performance and reliability.
7.1 Reworking to Correct Mistakes
Once installed, the scale, index marker, and limit markers cannot be moved or removed and
reinstalled. Reworking will require removal and discarding of the old scale or markers, and
installation of new ones.
If only the index or limit markers have to be replaced, the scale can remain in place and be
reused so long as there is no damage to the scale’s surface. Do not use a tool made of metal or
other hard material to remove the markers. Clean the
scale’s surface completely of any adhesive
residue before applying new markers.
7.2 Cleaning Scales
Step Action
1. General Particle Removal:
Blow off any contamination with nitrogen, clean air, or a similar gas.
2. Contamination Removal:
Use a lint-free cleanroom wipe or cotton swab dampened with isopropyl alcohol or acetone to
wipe the surface clean. Handle the scale by the edges. Do not scrub the scale.
