Gaging Procedures

Gaging Type-N Connectors

NOTE Always hold a connector gage by the gage barrel, below the dial indicator.
This gives the best stability, and improves measurement accuracy.
1. Select the proper gage for your connector. Refer to Table 6-2 on page 6-4 for gage part
numbers.
2. Inspect and clean the gage, gage master, and device to be gaged. Refer to "Visual
Inspection," and "Cleaning Connectors," earlier in this chapter.
3. Zero the connector gage (refer to Figure 3-3):
a. While holding the gage by the barrel, and without turning the gage or the gage
master, connect the gage to the gage master by interconnecting the male and female
connectors. Connect the nut finger tight. Do not overtighten.
b. Using an open-end wrench to keep the device body from rotating, use the torque
wrench recommended for use with this kit to tighten the connecting nut to the
specified torque. Refer to "Final Connection Using a Torque Wrench" on page 3-12 for
more information.
c. Loosen the dial lock screw on the gage and rotate the gage dial so that the pointer
corresponds to the correction value noted on the gage master. Do not adjust the gage
dial to zero, unless the correction value on the gage master is zero.
d. Tighten the dial lock screw and remove the gage master.
e. Attach and torque the gage master to the gage once again to verify that the setting is
repeatable. Remove the gage master.
4. Gage the device connector (refer to Figure 3-3):
a. While holding the gage by the barrel, and without turning the gage or the device,
connect the gage to the device by interconnecting the male and female connectors.
Connect the nut finger-tight. Do not overtighten.
b. Using an open-end wrench to keep the device body from rotating, use the torque
wrench recommended for use with this kit to tighten the connecting nut to the
specified torque. Refer to "Final Connection Using a Torque Wrench" on page 3-12 for
more information.
c. Gently tap the barrel of the gage with your finger to settle the gage reading.
d. Read the gage indicator dial. If the needle has moved clockwise, the center conductor
is protruding by an amount indicated by the black numbers. If the needle has moved
counterclockwise, the center conductor is recessed by an amount indicated by the red
numbers.
For maximum accuracy, measure the connector a minimum of three times and take
an average of the readings. After each measurement, rotate the gage a quarter-turn
to reduce measurement variations that result from the gage or the connector face not
being exactly perpendicular to the center axis.
e. Compare the average reading with the pin depth specifications listed in Table 2-3 on
page 2-4.
f. Without turning either the gage or the device, remove the device from the gage.
