Safety & Warnings
B+K Precision products are not authorized for use in any application involving direct contact with the human body or as a critical component in a life support device or system. Normal use of test equipment exposes users to electrical shock danger, especially when testing where high voltage is present. Voltage as low as 35 volts can be dangerous and potentially lethal. It is advised never to work alone, and training in CPR and first aid is recommended. Safety precautions include:
1. Be cautious of shock hazards with “hot chassis” equipment and use isolation transformers when necessary.
2. Do not float power supply output to more than 100 volts peak with respect to chassis or earth ground.
3. Discharge high-voltage capacitors before making connections or tests.
4. Use a polarized 3-wire AC outlet to ensure proper grounding.
5. Avoid exposing high voltage unnecessarily and discharge capacitors after removing power.
6. Familiarize yourself with the equipment and its high voltage points.
7. Use insulated floor material or mats and ensure surfaces are dry.
8. Be aware that AC line voltage is present on some circuits when equipment is connected to an AC outlet.
