between the supply conductors or between
either supply conductor and ground. A protective ground connection,
through the grounding conductor in the power cord, is essential for safe
system operation.
Grounding the Oscilloscope
The oscilloscope is grounded through the power cord. To avoid electric
shock, plug the power cord into a properly wired receptacle with an earth
ground connection. Do this before making connections to the input or output
terminals of the oscilloscope.
Without the protective ground connection, all parts of the oscilloscope are
potential shock hazards. This includes knobs and controls that may appear
to be insulators.
Use the Proper Power Cord
Use only the power cord and connector specified for your product. Use only
a power cord that is in good condition.
Use the Proper Fuse
To avoid fire hazard, use only a fuse that meets all type, voltage, and current
specifications on page 1Ć13.
Do Not Remove Covers or Panels
To avoid personal injury, do not operate the oscilloscope without the panels
or covers.
