3) Disconnection
Step 1. Support the connector to prevent any part from being shaken, distorted, or bent;
Step 2. Use an open-end wrench to prevent the main connector from rotating;
Step 3. Use another wrench to loosen the screw on the connector.
Step 4. Loosen the screw by hand until the connection is completely broken.
Step 5. Separate two connectors by pulling them apart in parallel.
4) Use of the torque wrench
The torque wrench should be used as indicated in Figure 2.6. Please pay attention to the following points
when using the torque wrench:

Confirm that the torque of the torque wrench is set correctly before use;

Ensure that the angle between the torque wrench and the other wrench (used to support the
connector or cable) is less than 90
o
before applying a force;

Gently grasp the end of the torque wrench handle and apply a force in the direction perpendicular to
the handle until the breakout torque of the wrench is reached.

5) Use and preservation of connectors
1) Protect the connectors with a protective sheath when not used;
2) Do not place the connectors, tools, etc. in a same box, which is the most common cause leading to
connector damage;
3) Keep the connector and analyzer at the same temperature. If the connector is held by hand or
cleaned with compressed air, the temperature will be significantly changed. The connector can be
used for calibration only after its temperature is stabilized;
4) Do not touch the joint surface of the connector because it is difficult to remove skin oil and dust
particles from the joint surface;
5) Do not place the contact surface of the connector downwards onto a hard surface; otherwise, the
electroplated layer and joint surface of the connector may be damaged.
