Use, Maintenance, and Care of the Devices
Gaging Connectors
Gaging the Sliding Loads
Gage a sliding load before each use. If the sliding load pin depth is out of the observed pin
depth limits listed in Table 2-2 on page 2-4 , refer to “Adjusting the Sliding Load Pin Depth” on
page 3-14 .
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.)
NOTE The sliding load uses a plastic centering bead to support its center conductor
when pin depth is adjusted and gaged and when the load is stored. Remove this
support bead from the sliding load before you connect the load for an electrical
calibration. Reinsert this support bead when you’ve finished using the sliding
load.
1. Select the proper gage for your connector. Refer to Table 6-1 on page 6-2 for gage part
numbers.
2. Inspect and clean the gage, gage master, and device to be gaged. Refer to “Visual
Inspection” on page 3-3 and “Cleaning Connectors” on page 3-4 earlier in this chapter.
3. Zero the connector gage as described in either (for a male gage) or (for a female gage).
4. Remove the center conductor protective cap from the sliding load.
5. Loosen the center conductor pull-back nut completely, and press the center-conductor cap
to extend the center conductor beyond the end of the connector. With the sliding ring pulled
back approximately 0.5 inch, install a centering bead (if not already installed) in the
connector end of the sliding load.
6. Continue to press the center conductor cap and mate the center conductor of the sliding
load with the gage’s center conductor.
CAUTION The sliding load center conductor can be damaged if the sliding load is not in line
when mating the load to a connector. Always line-up the sliding load when
connecting or removing it from a connector.
7. Mate the outer conductor of the sliding load with the outer conductor of the gage. Torque the
connection with a 3/4 inch torque wrench to approximately 135 N-cm (12 in-lb). Re-tighten
the center conductor pull-back nut. It will “click” when it is tight.
8. Gently tap the barrel of the gage with your finger to settle the gage reading.
9. Read the gage indicator dial. If the needle had moved clockwise, the center conductor is
protruding and the value is determined by the black numbers. If the needle had moved
counterclockwise, the center conductor is recessed by an amount determined by the red
numbers. 
