be used. Find the causes of damage before measurement connection.
3) Connection method
Check and clean the connector before measurement connection. Ensure that the connector is clean and intact. Wear
the anti-static wristband in connection. The correct connection method and steps are as follows.
Step 1 : as shown in Fig. 3.4, align the axes of two connectors to be interconnected, and ensure that the pin of
the male connector can concentrically slide into the jack of the female connector.

Step 2 : as shown in Fig. 3.5, horizontally move two connectors to make them connected smoothly. Tighten
the connector nut by means of rotation (do not rotate the connector). Avoid relative rotation of connectors
during connection.

Step 3 : as shown in Fig. 3.6, complete the final connection by tightening with the torque wrench. Note that the
torque wrench must not be beyond the initial break point. Use the auxiliary wrench to prevent the connectors
from rotation.

4) Disconnection method
Step 1 : support the connectors to prevent any kind of force which may result in distortion, shaking or bending.
Step 2 : use the open-end wrench to prevent the connector body from rotation.
Step 3 : use another wrench to loosen the connector nut.
Step 4 : rotate the connector nut by hand to complete final disconnection.
Step 5 : horizontally separate two connectors.
5) Use of torque wrench
The use of the torque wrench is shown in Fig. 3.7. Pay attention to the following items.
➢
Check whether the torque of the torque wrench is set properly before use.
➢
Ensure that the angle between the torque wrench and the other wrench (used to support the connector or cable)
