Safety & Warnings
Normal use of test equipment exposes users to electrical shock dangers, as testing often occurs where exposed voltage is present. A current of 10 milliamps passing through the heart can stop most human heartbeats, and voltages as low as 35 volts can be dangerous. Higher voltages pose a greater threat as they can more easily produce a lethal current. Users should follow accepted practices to avoid contact with high voltage and steer current away from the heart in case of accidental contact. Safety precautions include:
1. Avoid unnecessary exposure to high voltage. Remove housings and covers only when necessary and turn off equipment while making test connections in high-voltage circuits. Discharge high-voltage capacitors after removing power.
2. Familiarize yourself with the equipment being tested and the location of its high voltage points, but be aware that high voltage may appear unexpectedly in defective equipment.
3. Use insulated floor material or a large, insulated floor mat to stand on, and an insulated work surface for equipment. Ensure these surfaces are not damp or wet.
4. Use the “one hand in the pocket” technique while handling an instrument probe to avoid contacting a nearby metal object that could provide a ground return path.
5. Remember that ac line voltage is usually present on some power input circuits whenever the equipment is connected to an ac outlet, even if turned off.
6. Use a 3-wire outlet for test instruments or equipment with a 3-wire power plug to keep exposed elements at earth ground.
7. B+K Precision products are not authorized for direct contact with the human body or as critical components in life support devices or systems.
8. Never work alone. Someone should be nearby to render aid if necessary. Training in CPR (cardio-pulmonary resuscitation) and first aid is highly recommended.
