Gaging the Sliding Load

Gage the 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 3-13.

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 “Replaceable Parts for the 85054B Calibration Kit” on page 6-2for gage part numbers.

2.Inspect and clean the gage, gage master, and device to be gaged. Refer to “Visual Inspection” on page 3-3and “Cleaning Connectors” on page 3-4earlier in this chapter.

3.Zero the connector gage as described in either Step 3 on page 3-8(for a male gage) or Step 3 on page 3-10(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 held 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). Retighten 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.

10.For maximum accuracy, measure the connector a minimum of three times and take an average of the readings.
