Safety & Warnings
There is always a danger present when testing electronic equipment. Unexpected high voltages can be present at unusual locations in defective equipment. Every precaution has been taken in the design of your instrument to ensure that it is as safe as possible. However, safe operation depends on you, the operator. Become familiar with the equipment you’re working with, and observe the following safety precautions:
1. Never exceed the limits of this instrument as given in the specifications section and the additional special warnings in this manual.
2. A severe shock hazard can result if the chassis of the equipment being serviced is tied to the “hot” side of the AC line. An isolation transformer should always be used with hot-chassis equipment. Also, be sure that the top of your workbench and the floor underneath it are dry and made of non-conductive materials.
3. Remove the circuit power before making connections to high voltage points. If this cannot be done, be sure to 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.
4. Discharge filter capacitors (after removing power) before connecting to any part of the circuit requiring power to be removed.
5. Be sure your equipment is in good order. Broken or frayed test leads can be extremely dangerous and can expose you to dangerous voltages.
6. Remove the test lead immediately after the test has been completed to reduce the possibility of shock.
7. Do not work alone when working on hazardous circuits. Always have another person close by in case of an 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 high voltages.
