Visually inspect connectors for general wear, for cleanliness, and for damage, such as bent pins or connector rings. Repair or replace damaged connectors immediately. Dirty connectors can limit the accuracy of your measurements. Damaged connectors can damage the instrument. Connection of cables carrying an electrostatic potential, excess power, or excess voltage can damage the connector or the instrument or both. Connection of cables with inadequate torque settings can affect measurement accuracy. Over-torquing connectors can damage the cable, the connector, the instrument, or all of these items.
Connecting Procedure
1. Carefully align the connectors.
The male connector center pin must slip concentrically into the contact fingers of the female connector.
2. Push connectors straight together. Do not twist or screw them together.
3. To tighten, turn the connector nut, not the connector body. Major damage can occur to the center conductor and to the outer conductor if the connector body is twisted.
4. If you use a torque wrench, then initially tighten by hand so that approximately 1/8 turn or 45 degrees of rotation remains for the final tightening with the torque wrench.
Relieve any side pressure on the connection (such as from long or heavy cables) in order to assure consistent torque. Use an open‑end wrench to keep the connector body from turning while tightening with the torque wrench.
Do not over-torque the connector.
Disconnecting Procedure
1. If a wrench is needed, use an open‑end wrench to keep the connector body from turning while loosening with a second wrench.
2. Complete the disconnection by hand, turning only the connector nut.
3. Pull the connectors straight apart without twisting or bending.
