Gaging Procedures

Gaging 3.5 mm Connectors
NOTE Always hold a connector gage by the gage barrel, below the dial indicator.
This gives the best stability, and improves measurement accuracy. (Cradling
the gage in your hand or holding it by the dial applies stress to the gage
plunger mechanism through the dial indicator housing.)
1. Select the proper gage for your connector. Refer to
numbers.
2. Inspect and clean the gage, gage master, and device to be gaged. Refer to
Inspection" and "Cleaning Connectors"
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 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 included in the kit to tighten the connecting nut to the specified torque. Refer
to "Final Connection Using a Torque Wrench" on page 3-10
information.
c. As you watch the gage pointer, gently tap the barrel of the gage to settle the reading.
The gage pointer should line up exactly with the zero mark on the gage. If not, adjust
the zero set knob until the gage pointer lines up exactly with the zero mark.
d. 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 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 included in the kit to tighten the connecting nut to the specified torque. Refer
to "Final Connection Using a Torque Wrench" on page 3-10
information.
c. Gently tap the barrel of the gage with your finger to settle the gage reading.
d. Read the gage indicator dial. Read only the black ± signs; not the red ± signs.
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 observed pin depth limits in
2-4.
