PRECAUTIONS
FOR PERSONAL AND INSTRUMENT PROTECTION
IMPORTANT:
1. Before using any electrical instrument, it should be checked to make certain it is
operating properly.
2. In many instances, you will be working with dangerous levels of voltages and/or current,
therefore, it is important that you avoid direct contact with any uninsulated, current
carrying surfaces. Appropriate insulated gloves and protective clothing should be worn.
3. Before attaching any of the conductors, make sure the voltage present is not beyond
the range of the instrument.
4. When not in use, keep the instruments in their carrying case.
5. When the R-4000 or the T-4000 will not be used for a period of time, remove the
battery to prevent leakage in the instrument.
