Strain On Surface Where Equipment Is Installed - Pioneer PDM-4001 Technical Manual

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.
* Regarding the distortion of 1 mm or below:
It is possible that the housing of this device causes a maximum distortion of about 3 mm. It is also possible that
this device causes stress on the glass when this device suffers a distortion of 4 mm or more. Therefore, make
sure to keep the distortion on the mounting surface within 1 mm so that the total distortion should remain less
than 4 mm including the distortion of the housing itself under it.
