NOTE
A minimum magnification of 10X is required for all inspections of the 1.0-mm connector parts.
NOTE
When using isopropyl alcohol to clean connectors do not allow liquid to flow down inside the
connector. This may cause measurement errors due to residue inside the connector. If possible
keep the connector facing down.
