Safety & Warnings
Normal use of test equipment exposes users to potential electrical shock hazards, especially when testing in areas with high voltage. To reduce risk, the manual advises:
1. Avoid unnecessary exposure to high voltage. Only remove housings and covers when needed.
2. Turn off equipment when making test connections in high-voltage circuits and discharge high-voltage capacitors after removing power.
3. Familiarize yourself with the equipment and its high voltage points, but be aware that high voltage may appear unexpectedly in defective equipment.
4. Use insulated floor material or a large, insulated floor mat, and ensure work surfaces are not damp or wet.
5. Employ the “one hand in the pocket” technique when handling an instrument probe to avoid creating a ground return path.
6. Only touch the insulated portion of a probe, never the exposed tip.
7. Remember that ac line voltage is often present in some power input circuits whenever equipment is connected to an ac outlet, even if turned off.
8. For “hot chassis” equipment, use an isolation transformer between the ac outlet and the equipment under test to prevent shock hazards and potential damage.
9. Never work alone; someone should be nearby to provide aid if necessary. Training in CPR is recommended.
