SENCORE SAFETY REMINDERS
When testing electronic equipment, there is always a danger present. Unexpected high voltages
can be present at unusual locations in defective equipment. The technician should become
familiar with the device he is working on and observe the following precautions.
1. An isolation transformer should always be used on equipment having the chassis tied to
one side of the AC power line. The case of the PS163 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. In addition, as soon as the PS163 ground lead is connected to the chassis the
resultant short circuit will fuse the ground clip of the scope to the chassis of the equip-
ment being serviced, and blow the fuse to your service bench.
2. When making test lead connections to high voltage points, remove the power. If this can-
not be done, be sure to avoid contact with other equipment or metal objects. Place one
hand in your pocket as a safety precaution and stand on an insulated floor to reduce the
possibility of shock.
3. Discharge filter capacitors before connecting test leads to them. Capacitors can store a
charge that could be dangerous to the technician.
4. Be sure your equipment is in good order. Broken or frayed test leads can be extremely
dangerous and can expose the technician to dangerous potentials.
5. Remove the test leads immediately after the test has been completed to reduce the
possibility of shock.
6. Do not work alone when working on hazardous circuits. Always have another person
close by in case of accident. Remember, even a minor shock can be the cause of a more
serious accident, such as falling against the equipment, or coming in contact with higher
voltages.
