Safety & Warnings
When testing electronic equipment, there is always a danger present due to unexpected high voltages at unusual locations in defective equipment. Technicians should become familiar with the device they are working on and observe the following precautions:
1. Use an isolation transformer on equipment with the chassis tied to one side of the AC power line. The case of the PS29 is connected to the earth ground side of the AC line through the third wire of the line cord. If the chassis of the equipment being serviced is connected to the other side of the AC line, a severe shock hazard will be present. Connecting the PS29 ground lead to the chassis can result in a short circuit, fusing the ground clip of the scope to the chassis and blowing the fuse to the service bench.
2. Remove power when making test lead connections to high voltage points. If this cannot be done, avoid contact with other equipment or metal objects, place one hand in your pocket, and stand on an insulated floor to reduce the possibility of shock.
3. Discharge filter capacitors before connecting test leads to them, as capacitors can store a charge that could be dangerous.
4. Ensure equipment is in good order, as broken or frayed test leads can be extremely dangerous and expose the technician to dangerous potentials.
5. Remove test leads immediately after completing the test to reduce the possibility of shock.
6. Do not work alone on hazardous circuits. Always have another person close by in case of an accident, as even a minor shock can cause a more serious accident, such as falling against the equipment or coming in contact with higher voltages.
