How To Install; Setting Operation - Magnescale LH70 Quick Reference Manual

2-3. How to install

A typical example for pasting scales in parallel is shown below.
SL130 and SL331 have a strong scale base material, so if they are
attached to an arc surface, the scale edge may bounce off. It is
recommended to fix the base material of the scale with a suitable
clamp plate.
For more information on pasting scales, refer to the head unit
instruction manual.
Typical example of how to install
(1) Set up parallel pins on the flat
surface and attach the scale. Remove
the parallel pin after installation.

2-4. Setting operation

First of all, in the basic settings, set the length measurement unit resolution to the output resolution of the connected digiruler. For
details on the basic settings, refer to the separate initial setup manual of display unit. Then enter the display resolution and mounting
radius values in the advanced settings. Compare the mounting radius value with an angle reference device (right angle ruler: 90
degrees), etc., and narrow down the radius value so that the angle error is minimized.
In the basic settings, set the output resolution of the connected digital ruler.

*: If the radius cannot be entered and an error occurs, the angle display for the measurement unit is too small, so increase the radius or
coarsen the resolution of the angle display.
(2) Make a stop surface for mounting
the scale. Consider the thickness of
the scale and the amount of clearance
