to a circuit point at which the voltage with
respect to earth ground exceeds (in this case)
600 VAC or VDC.
This symbol adjacent to one or more terminals
identifies them as being associated with
ranges that may, in normal use, be subjected
to particularly hazardous voltages. For
maximum safety, the meter and its test leads
should not be handled when these terminals
are energized.
This symbol indicates that a device is
protected throughout by double insulation or
reinforced insulation.
This symbol indicates there is a potential
hazard from a laser light source.
