Operating Ranges
This table lists the ranges of external conditions in which the W3013 provides general functionality that may be
useful in specific applications without risk of permanent damage. However, performance is not guaranteed over
the full range of all possible conditions. The conditions for guaranteed performance are described in the
Electrical Characteristics table.
