Use, Maintenance, and Care of the Devices
Gaging Connectors
10.For maximum accuracy, measure the connector a minimum of three times and take an
average of the readings.
NOTE When performing pin depth measurements, use different orientations of the gage
within the connector. Averaging a minimum of three readings, each taken after a
quarter-turn rotation of the gage, reduces measurement variations that result
from the gage or the connector face not being exactly perpendicular to the center
axis.
11.Compare the average reading with the observed pin depth limits in Table 2-2 on page 2-4 . If
the pin depth is outside the limits, it must be adjusted before proceeding. Refer to “Adjusting
the Sliding Load Pin Depth” on page 3-14 .
12.Loosen the connection between the gage and sliding load, and remove the sliding load from
the gage.
13.Leave the centering bead installed on the sliding load if you are going to adjust the pin
depth. Carefully remove the centering bead from the sliding load if you’re going to use it for
an electrical calibration. If the centering bead does not come out of the sliding load easily,
loosen the center conductor pull-back nut, and press the center conductor cap to extend the
center conductor. This should expose the centering bead so that it may be removed. Retract
the center conductor and retighten the pull-back nut.
If the centering bead still will not come out, hold the sliding load with the connector end
pointed down. Move the sliding element up, then quickly down. The trapped air behind the
centering bead helps eject it.
CAUTION Damage can occur to the sliding load during the removal of a centering bead that
has slipped too far into the sliding load. If you’re going to perform an electrical
calibration, prevent damage by removing the centering bead immediately after
aligning the sliding load pin depth. The sliding load will not perform to its
specifications if the centering bead is not removed from the sliding load before an
electrical calibration.
