Installation conditions
3.2.4 Strain on surface where equipment is installed
1
This display uses glass in its display section. When using a third-party metal fixture, check that strain is 1 mm or
less by the following method.
2
Tightly fit a thread using a force of
φ
0.1psi or less diagonally through the mounting bolt openings on the mounting
surface, as shown in the drawing.
3
Measure distance L of the intersection of the strings in the center section.
The relationship between strain and L is given by Strain = L
×
2.
4
If L is 0, interchange the front and rear positions of two strings and check the distance again. If the value of L is not
0, it is the true value of L. If L is 0 after the position is changed, strain is approximately 0.
