Use, Maintenance, and Care of the Devices
Gaging Connectors
If the pin depth is outside the observed limits listed in Table 2-2 on page 2-4, use the
following procedure to reset it. Always measure the sliding load pin depth before attaching
it to any connector.
This procedure assumes that you were directed here from “Gaging the Sliding Load” on
page 3-12. If not, perform the steps in that procedure before performing this procedure.
1. The gage should be attached to the sliding load. The sliding load should have its
centering bead installed. Refer to “Gaging the Sliding Load” on page 3-12 if necessary.
2. With a 0.050 inch hex key, loosen the two largest hex screws by turning them 1/4 turn
clockwise. Refer to Figure 3-6.
CAUTION Do not loosen any hex screws other than the two largest hex screws pointed
out in Figure 3-6.
3. Gently turn the center conductor pin depth adjustment knob on the sliding load until
the gage pointer reads −3.81 micrometers (−1.5 x 10
–4
inches). Refer to Figure 3-6.
4. Tighten the two hex screws just until they are finger tight (do not overtighten).
5. Wait approximately five minutes to allow the temperature to stabilize. Do not touch
either the gage or the sliding load during this time.
6. Note the gage reading. If it is no longer within the allowable range, perform steps 2–5
again.
7. Loosen the connecting nut and remove the gage from the sliding load. If you’re going to
store the sliding load, leave the centering bead installed. If you’re gong to use the
sliding load for an electrical calibration, remove the centering bead.
NOTE When performing pin depth measurements, use different orientations of the
gage within the connector. Averaging a minimum of three readings, each
taken after a quarter-turn rotation of the gage, reduces measurement
variations that result from the gage or the connector face not being exactly
perpendicular to the center axis.
The sliding load pin depth is now is specification and the load is ready to use. Once the
sliding load pin depth is set it rarely needs to be adjusted. However, the pin depth should
be rechecked before each use. Replace the protective plastic caps on the sliding load and
gage connectors when these devices are not in use.
