connected to a circuit point at which the
voltage with respect to earth ground
exceeds (in this case) 500 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.
