Safety & Warnings
Normal use of test equipment exposes users to electrical shock hazards, as testing often involves exposed voltage. A current of 10 milliamps passing through the heart can be lethal, and voltages as low as 35 volts DC or AC RMS should be considered dangerous. Higher voltages increase the risk of lethal current. To reduce risk, follow these safety precautions:
1. Some equipment with a two-wire AC power cord may have a “hot chassis.” When servicing, use an isolation transformer to prevent shock hazards and damage to test instruments. Treat all two-wire AC equipment as “hot-chassis” unless confirmed otherwise.
2. Use a 3-wire outlet for test instruments or equipment with a 3-wire AC power plug to ensure safety by keeping exposed elements at earth ground.
3. B+K Precision products are not authorized for direct contact with the human body or as critical components in life support devices.
4. Never work alone. Have someone nearby to provide aid if necessary, and training in CPR is highly recommended.
5. Avoid exposing high voltage unnecessarily. Remove housings and covers only when needed, turn off equipment when making test connections, and discharge high-voltage capacitors after removing power.
6. Familiarize yourself with the equipment and high voltage points, but be aware that high voltage may appear unexpectedly in defective equipment.
7. Use insulated floor material or a large, insulated floor mat, and ensure work surfaces are not damp or wet.
8. Use the “one hand in the pocket” technique while handling instrument probes to avoid creating a ground return path.
9. 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.
