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 lethal, and voltages as low as 35 volts can be dangerous. To reduce risk, adhere to safety precautions:
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 and 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 mat to stand on, and ensure work surfaces are not damp or wet.
4. Use the “one hand in the pocket” technique when handling an instrument probe to avoid providing a ground return path.
5. Remember that ac line voltage is often present on power input circuits even if the equipment is turned off.
6. For equipment with a two-wire ac power cord, use an isolation transformer to prevent shock hazards and damage to test instruments.
7. Use only a 3-wire outlet for test instruments or equipment with a 3-wire power plug to keep exposed elements at earth ground.
8. B+K Precision products are not authorized for use involving direct contact with the human body or as critical components in life support devices.
9. Never work alone; someone should be nearby to render aid if necessary. Training in CPR and first aid is recommended.
