Observe all of these precautions to ensure your personal safety and to
prevent damage to either the digitizing oscilloscope or equipment conĆ
nected to it.
Power Source
The digitizing oscilloscope is intended to operate from a power source that
will not apply more than 250 V
RMS
between the supply conductors or beĆ
tween 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 Digitizing Oscilloscope
The digitizing oscilloscope is grounded through the power cord. To avoid
electric shock, plug the power cord into a properly wired receptacle where
earth ground has been verified by a qualified service person. Do this before
making connections to the input or output terminals of the digitizing oscilloĆ
scope.
Without the protective ground connection, all parts of the digitizing oscilloĆ
scope 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 the fuse specified in the parts list for your
product, matched by type, voltage rating, and current rating.
Do Not Remove Covers or Panels
To avoid personal injury, do not operate the digitizing oscilloscope without
the panels or covers.
Electric Overload
Never apply a voltage to a connector on the digitizing oscilloscope that is
outside the voltage range specified for that connector.
Do Not Operate in Explosive Atmospheres
The digitizing oscilloscope provides no explosion protection from static
discharges or arcing components. Do not operate the digitizing oscilloscope
in an atmosphere of explosive gases.
