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.
Select the proper gage for your connector. Refer to
1.
Inspect and clean the gage, gage master, and device to be gaged. Refer to
2.
page 3-3 and "Cleaning Connectors" on page 3-4
Zero the connector gage (refer to
3.
While holding the gage by the barrel, and without turning the gage or the device, connect the
a.
gage master to the gage. Refer to
the nut finger tight. Do not overtighten.
Using an open-end wrench to keep the gage from rotating, use the torque wrench
b.
recommended for use with the kit to tighten the gage master connector nut to the specified
torque. Refer to
information.
The gage pointer should line up exactly with the zero mark on the gage. If not, loosen the dial
c.
lock screw on the gage and rotate the gage dial so that the pointer is aligned with the zero
mark.
Tighten the dial lock screw and remove the gage master.
d.
Attach and torque the gage master to the gage once again to verify that the setting is
e.
repeatable. Remove the gage master.
Gage the device connector (refer to
4.
If gaging one of the 50Ω loads in the kit, use a collet extractor tool to remove the center
a.
conductor collet from the device connector to be gaged. Refer to
part number of this extractor tool. Refer to
mm connector and the location of the center conductor collet.
While holding the gage by the barrel, and without turning the gage or the device, connect the
b.
gage master to the device. Refer to
the nut finger-tight. Do not overtighten.
Using an open-end wrench to keep the gage from rotating, use the torque wrench
c.
recommended for use with the kit to tighten the device connector nut to the specified torque.
Refer to "Final Connection Using a Torque Wrench" on page 3-13
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
e.
protruding by and 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
