Tips for Preventing Damage 1
Final connection using a torque wrench
• Use a torque wrench to make a final connection. Using a torque wrench
guarantees that the connection is not too tight, preventing possible
connector damage.
It also guarantees that all connections are equally tight each time.
• Prevent the rotation of anything other than the connector nut that you
are tightening.
Ensure proper grounding
• Always use the three-prong AC power cord supplied with the product.
• Proper grounding of the instrument will prevent a build-up of
electrostatic charge, which may be harmful to the instrument and the
operator.
• Do not damage the earth-grounding protection by using an extension
cable, power cable or autotransformer without a protective ground
conductor.
