• Use a scale installation bracket, where applicable, having length covering the entire scale length. Th e
parallelism of the scale may be harmed if only using a bracket divided for the installation section.
Before installation
• Check that the alignment of the installation surface (or installation brackets) is within the standards.
(For the standards, see the later-described illustration of the Installation example)
• Remove off the coating around the tap hole to ground the scale unit using the installation surface
contact with the scale.
For details on the installation method, see the later-described example installation.
• Th e foot plates and intermediate foot plate(s) installed on the scale are used as the installation guides.
Th e head holders are used for securing the scale head when transporting the head holders and cannot
therefore be used as an installation guide.
• Loosely turn the mounting screws fi rst. Determine the alignment and then tighten the screws to fasten
the scale. (See Fig. 2-3)
