Safety & Warnings
Normal use of test equipment can expose users to electrical shock, especially when testing where exposed voltage is present. A current of 10 milliamps passing through the heart can be fatal, and voltages as low as 35 volts can be dangerous. Higher voltages pose even greater risks. To reduce these risks, follow these precautions:
– Avoid exposing high voltage unnecessarily. Remove housings and covers only when necessary, turn off equipment while making test connections in high voltage circuits, and discharge high voltage capacitors after removing power.
– Familiarize yourself with the equipment being tested and the location of its high voltage points, but remember that high voltage may appear unexpectedly in defective equipment.
– Use insulated floor material or a large, insulated floor to stand on, and an insulated work surface for equipment. Ensure these surfaces are not damp or wet.
– Use the “one hand in the pocket” technique while handling an instrument probe to avoid creating a ground return path.
– Remember that ac line voltage is usually present on some power input circuits whenever equipment is connected to an ac outlet, even if turned off.
– Treat all two-wire ac equipment as “hot chassis” unless you are sure it is isolated or earth ground chassis. Always connect an isolation transformer between the ac outlet and the equipment under test.
– Use only a 3-wire outlet for equipment with a 3-wire ac power plug to keep exposed elements at earth ground.
– B&K Precision products are not authorized for use in applications involving direct contact with the human body or as critical components in life support devices or systems.
– Never work alone. Someone should be nearby to provide aid if necessary. Training in CPR and first aid is recommended.
