3- 10 85052BUse, Maintenance, and Care of the DevicesGaging ConnectorsGaging the 3.5 mm Sliding LoadsGage the sliding load before each use. If the sliding load pin depth is out of the observed pin depth limitslisted in Table 2-2 on page 2-4, refer to “Adjusting the Sliding Load Pin Depth” on page 3-12.NOTE Always hold a connector gage by the gage barrel, below the dial indicator. This gives thebest stability, and improves measurement accuracy. (Cradling the gage in your hand orholding it by the dial applies stress to the gage plunger mechanism through the dialindicator housing.)NOTE The sliding load uses a plastic centering bead to support its center conductor when pindepth is adjusted and gaged and when the load is stored. Remove this support bead fromthe sliding load before you connect the load for an electrical calibration. Reinsert thissupport 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 page3-3 and “Cleaning Connectors” on page 3-4 earlier in this chapter.3. Zero the connector gage (refer to Figure 3-2 on page 3-9):a. While holding the gage by the barrel, and without turning the gage or the device, connect the gageto 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 includedin the kit to tighten the connecting nut to the specified torque. Refer to “Final Connection Using aTorque Wrench” on page 3-14 for additional 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 setknob until the gage pointer lines up exactly with the zero mark.d. Remove the gage master.4. Gage the sliding load connector (refer to Figure 3-3):a. Unlock the center conductor pullback mechanism by raising the pullback handle to the unlockedposition.b. Carefully move the pullback mechanism toward the connector end of the sliding load. The centerconductor will extend beyond the end of the connector. Continue to hold the pullback mechanism inthis position.c. Pull the sliding ring back approximately 0.5 in and install a centering bead (if not already installed) inthe connector end of the sliding load.CAUTION The sliding load center conductor can be damaged if the sliding load is not in alignmentwith the mating connector while making the connection.
