Safety & Warnings
Normal use of test equipment exposes users to electrical shock hazards. A current of 10 milliamps passing through the heart can be lethal, and voltages as low as 35 volts can produce a lethal current under certain conditions. To reduce risk, follow these precautions:
1. Avoid unnecessary exposure to high voltage. Remove housings and covers only when necessary and turn off equipment when 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. 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 when handling an instrument probe to avoid creating a ground return path.
5. 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.
6. Some equipment with a two-wire ac power cord may have a “hot chassis.” Use an isolation transformer when testing such equipment to prevent shock hazards and damage.
7. Use a 3-wire outlet for equipment with a 3-wire ac power plug to keep exposed elements at earth ground.
8. B+K Precision products are not authorized for use in direct contact with the human body or as critical components in life support devices.
9. Never work alone. Ensure someone is nearby to provide aid if necessary, and training in CPR is highly recommended.
