3- 16 85052BUse, Maintenance, and Care of the DevicesConnectionsCAUTION You don’t have to fully break the handle of the torque wrench to reach the specified torque;doing so can cause the handle to kick back and loosen the connection. Any give at all in thehandle is sufficient torque.Connecting the Sliding LoadNOTE 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. Unlock the center conductor pullback mechanism by raising the pullback handle to the unlockedposition. Refer to Figure 3-7.2. Carefully move the pullback mechanism toward the connector end of the sliding load. The centerconductor will extend beyond the end of the conductor. Continue to hold the pullback mechanism in thisposition.CAUTION The sliding load center conductor can be damaged if the sliding load is not in alignmentwith the mating connector while making the connection.3. Keep the center conductor extended by holding the center conductor pullback mechanism toward theconnector end of the sliding load. Align the sliding load with the mating connector on the cable or testport to which it is being connected and mate the sliding load center conductor with the centerconductor of the cable or test port.4. Release the center conductor pullback mechanism and move the body of the sliding load toward thecable or test port to mate the outer conductor of the sliding load connector to the outer conductor ofthe cable or test port connector.5. Without turning the sliding load, connect the sliding load to the cable or test port by interconnecting themale and female connectors. Connect the nut finger-tight. Do not overtighten.6. Using an open-end wrench to keep the device body from rotating, use the torque wrench included in thekit to tighten the connecting nut to the specified torque. Refer to“Final Connection Using a Torque Wrench” on page 3-14 for additional information.CAUTION Always move the center conductor pullback mechanism back before locking the handle. Donot force the handle past the locked position.7. Move the center conductor pullback mechanism back (away from the connector end of the sliding load),and place the pullback handle in its locked position.
