Adjusting The Sliding Load Pin Depth - Agilent Technologies 85056A User's And Service Manual

Use, Maintenance, and Care of the Devices
Gaging Connectors
l. Without turning the gage or the sliding load, loosen the connection between the gage and the sliding
load and remove the sliding load from the gage.
CAUTION Damage can occur to the sliding load during the removal of a centering bead that has slipped
too far into the sliding load. If you're going to perform an electrical calibration, prevent
damage by removing the centering bead immediately after aligning the sliding load pin
depth. The sliding load will not perform to its specifications if the centering bead is not
removed from the sliding load before an electrical calibration.
m. Leave the centering bead installed on the sliding load if you are going to adjust the pin depth.
Carefully remove the centering bead from the sliding load if you're going to use it for an electrical
calibration. If the centering bead does not come out of the sliding load easily:
i. Unlock the center conductor pullback handle and move the center conductor pullback mechanism
toward the connector end of the sliding load to extend the center conductor.
ii. While holding the center conductor pullback mechanism toward the connector end of the sliding
load, remove the centering bead.
If the centering bead still will not come out:
i. Hold the sliding load with the connector end pointed downward.
ii. Move the sliding ring up, then quickly down. The trapped air behind the centering bead should
eject it.
Return the center conductor pullback mechanism to the rear of the sliding load and return the
pullback handle to its locked position.

Adjusting the Sliding Load Pin Depth

The sliding loads in this kit have a setback mechanism that allows the pin depth to be set to any desired
value. The pin depth of the sliding load is preset at the factory. The pin depth should not have to be reset
each time the sliding load is used, but it should be checked before each use.
If the pin depth is outside the observed limits listed in
reset it to the nominal value of -0.00381 mm (-0.00015 in).

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 2.4 mm Sliding Loads" on page 3-10
2. The face of the gage and the label on the sliding load should be facing up.
3. The center conductor pullback handle should be in the locked position.
4. With a small screwdriver, gently turn the center conductor pin depth adjustment screw until the gage

pointer reads 0.00381 mm (0.00015 in). Refer to
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 step 4 again.
7. Move the center conductor pullback handle to the unlocked position and then back to the locked
