To inspect the crimp height, proceed as follows:
1. Crimp the contact according to Section 3,
CRIMPING PROCEDURE.
2. Measure across opposite indents in the contact,
then rotate the contact 90 degrees, and measure
again. See Figure 10. DO NOT go beyond initial
contact as this could cause a depression and result
in an inaccurate reading.
