Connecting The Airline - Agilent Technologies 85051B User's And Service Manual

Use, Maintenance, and Care of the Devices
Making Connections
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.
4. Tighten the connection just to the torque wrench break point. The wrench handle gives way at its
internal pivot point. See

50 Airline and 25 Mismatch Airline
NOTE Before making any connections to the test set, be sure that bias power to the test set is OFF
and take care to avoid electrostatic discharge. Refer to
page 3-2.
CAUTION Be especially careful not to drop either the center conductor or the outer conductor when
handling these airlines. Irreparable damage will result if these devices are dropped.
NOTE Detachable spring-loaded tips are supplied with the center conductors of both the airline and
mismatch airline in your 85051B kit. Do not use these tips when connecting the airlines to
the TRL adapters supplied in the 85050C 7 mm Precision Calibration Kit.
When you are using these airlines to verify analyzer performance affected with the 85050 7
mm Precision Calibration Kit, substitute the normal tips with the special colleted
spring-loaded tips. These tips are included in your 85050C Calibration Kit to allow proper
contact between the center conductors of the airlines and the non-colleted TRL adaptors on
the test ports. The colleted tips will not interfere when connecting the airlines to standard
colleted test ports.
1. Connect test cables to port 1 and port 2 as they were connected during your calibration procedure.
2. Fully retract the threads on the port 1 cable connector.
NOTE This procedure refers to the "A" end of the airline as the end closest to the "A" in the Agilent
logo on the label of the outer conductor. The other end will be referred to as the "B" end. See
Figure 3-8 on page
