Gaging Procedure

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
2. Inspect and clean the gage, gage master, and device to be gaged. Refer to
page 3-3 and "Cleaning Connectors" on page 3-4
3. Zero the connector gage (refer to
a. While holding the gage by the barrel, and without turning the gage or the device, connect the gage
master to the gage. Refer to
nut finger tight. Do not overtighten.
b. Using an open-end wrench to keep the gage from rotating, use the torque wrench recommended for
use with the kit to tighten the gage master connector nut to the specified torque. Refer to
Connection Using a Torque Wrench" on page 3-12
c. The gage pointer should line up exactly with the zero mark on the gage. If not, loosen the dial lock
screw on the gage and rotate the gage dial so that the pointer is aligned with the zero mark.
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
a. While holding the gage by the barrel, and without turning the gage or the device, connect the gage
master to the gage. Refer to
nut finger-tight. Do not overtighten.
b. Using an open-end wrench to keep the gage from rotating, use the torque wrench recommended for
use with the kit to tighten the device connector nut to the specified torque. Refer to
Connection Using a Torque Wrench" on page 3-12
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.
