Hazardous voltages may be present in unexpected locations in circuitry being tested when a 
fault condition in the circuit exists. 
Fuse Replacement 
Fuse replacement must be done by qualified service-trained maintenance personnel who are 
aware of the instrument's fuse requirements and safe replacement procedures. Disconnect the 
instrument from the power line before replacing fuses. Replace fuses only with new fuses of 
the fuse types, voltage ratings, and current ratings specified in this manual or on the back of the 
instrument. Failure to do so may damage the instrument, lead to a safety hazard, or cause a 
fire. Failure to use the specified fuses will void the warranty.
