This symbol adjacent to another symbol, terminal or operating device
indicates that the operator must refer to an explanation in the operat-
ing instructions to avoid personal injury or damage to the meter.
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.
Double insulation.
This WARNING symbol indicates a potentially hazardous situation,
which if not avoided, could result in death or serious injury.
This CAUTION symbol indicates a potentially hazardous situation,
which if not avoided, may result in damage to the product.
This symbol advises the user that the terminal(s) so marked must not
be connected to a circuit point at which the voltage, with respect to
earth ground, exceeds 1000 V AC or V DC.
