Agilent Technologies 85054-90049 manual Connecting the Sliding Load

Use, Maintenance, and Care of the Devices

Connections

3.Apply downward force perpendicular to the wrench handle. See Figure 3-8. This applies torque to the connection through the wrench.

Do not hold the wrench so tightly that you push the handle straight down along its length rather than pivoting it, otherwise you apply an unknown amount of torque.

4.Tighten the connection just to the torque wrench break point. The wrench handle gives way at its internal pivot point. See Figure 3-8. Do not tighten the connection further.

CAUTION 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 the handle is sufficient torque.

Do not pivot the wrench handle on your thumb or other fingers, otherwise you apply an unknown amount of torque to the connection when the wrench reaches its break point.

Do not twist the head of the wrench relative to the outer conductor mating plane. If you do, you apply more than the recommended torque.

Connecting the Sliding Load

Use this procedure to connect the sliding load to a test port or a type-N cable connector.

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.
CAUTION	Circuitry inside the test set at the test ports may be destroyed if precautions
	are not taken to avoid electrostatic discharge (ESD). During this procedure,
	the center conductor of the sliding load is connected to the exposed center
	conductor of the test port. Ground yourself to prevent electrostatic discharge.

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.

1.Refer to Figure 3-9. Loosen the center conductor pull-back nut completely. Press the center conductor cap to extend the center conductor of the sliding load beyond the end of the connector.

2.Continue to press the center conductor cap and mate the center conductor of the sliding load with the cable/test port connector’s center conductor.
