There is always a danger present when using electronic test 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 insure that it is as safe as possible. However, safe operation depends on you, the operator. Become familiar with the equipment you are working with, and observe the following safety precautions. 1. Never exceed the limits of this instrument as given in the specifications section or other special warnings provided 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 test leads 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. 8. Improper Fuse(s) Void Warranty. Fuses are for your protection, so always replace fuse with proper type and current rating. The proper fuse type description is marked near the fuse holder and in the manual. Always: A. Be sure you are replacing the right fuse. On units with more than one fuse, be sure you are placing the proper fuse value in the fuse holder. B. Have the proper size replacement fuse in stock. With each new instrument, be sure to update your fuse inventory with any special value fuses your instrument may require. 9. Explanation of symbols. This marking indicates that the operator must refer to an explanation in the operating instructions. A terminal at which a voltage with respect to another terminal or part exists or may be adjusted to 1,000 volts or more.
