Making Connections
Good connections are essential for accurate measurements. Operators
must be very precise when making connections to ensure that accurate
measurements are taken.
CAUTION
This procedure assumes that you have taken the necessary ESD
precautions, and that you have already cleaned and inspected (visually
and mechanically) the connectors. Refer to
for a description of ESD precautions.
CAUTION
You can damage the RF ECal modules if you apply excessive torque to
the RF connectors. Do not exceed the recommended specifications listed
on
“Torque Wrench Information” on page 2-16
disconnecting RF ECal modules.
Using a Torque Wrench
1. Hand tighten the connection to be torqued. Be sure to keep the
connectors from rotating relative to each other. Turn the coupling
nut only.
CAUTION
Rotating connectors relative to each other during the
connect/disconnect cycle is the leading cause of connector wear.
2. Hold the torque wrench with your thumb and index finger behind
the groove in the handle.
3. Tighten the connection until the handle begins to break loose. It is
not necessary to fully break the handle of the torque wrench to reach
the specified torque (see
