Note the following aspects during actual use:
1) Check of connectors
It is necessary to wear an anti-static wrist strap when checking the connectors. It is recommended to use
a magnifier to check:
1) the electroplated surface for wear and deep scratches;
2) the thread for deformation;
3) the thread and joint surface for metallic particles;
4) the inner conductor for bending and breakage;
5) the screw for improper rotation.
Check the connectors so as not to damage the instrument ports
Any damaged connector may damage the good connector connected to it even for the first time of
measurement. To protect the ports of the USB CW power sensor, the connector to be used shall be
checked before connection.
2) Connection
The connectors should be checked and cleaned before measurement and connection to ensure that
they are clean and undamaged. It is necessary to wear an anti-static wrist strap during connection. The
correct connection methods and procedures are as follows:
Step 1. As shown in Figure 2.3, align the axes of the two interconnected connectors to ensure that the
pin of the male connector slides concentrically into the hole of the female connector.
Fig. 2.3 Coaxial Alignment of Interconnected Connectors
Step 2. As shown in Fig. 2.4, move both connectors straight together, so that they can be connected
smoothly; rotate the threaded sleeve of connector (rather than the connector itself) until it is tightened;
during connection, there can be no relative rotary motion both connectors;

Step 3. As shown in Fig. 2.5, use a torque wrench to tighten the connectors and finish the connection;
the torque wrench shall not exceed the starting break point and an auxiliary wrench can be used to
prevent the connector rotating.
