This symbol adjacent to another symbol, terminal or operating device indicates that the
operator must refer to an explanation in the Operating Instructions to avoid personal injury
or damage to the meter.
This
symbol indicates a potentially hazardous situation, which if not
avoided, could result in death or serious injury.
This
symbol indicates a potentially hazardous situation, which if not
avoided, may result 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 (in this case) 1000
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 par ticularly 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.
Equipment of OVERVOLTAGE CATEGORY I is equipment for connection to circuits in which
measures are taken to limit the transient overvoltages to an appropriate low level.
– Examples include protected electronic circuits.
