3.2.4 Mounting surface warping
The display section incorporates glass. Before mounting the product, perform the following to confirm that the display
is free of warps exceeding 1 mm.
1 Referring to the illustration below, diagonally extend string of maximum 0.1-mm diameter through the bolt mount
openings. Strings thus arranged should be completely free of slack.
2 Measure the clearance (L) between the strings at their point of intersection. Distortion is expressed by: Distortion =
L x 2.
3 If L is found to be 0, pass the strings through the other bolt mount openings and repeat the measurements. Any
value of L greater than 0 indicates the presence of distortion. If the measured values in both cases is 0, the distortion
is negligible.
