    Patent number: 6635167
    Abstract: An instrument (20) has a well (28a-b) for receiving a dry cell (75), an opening (78) through which a first connector (74) is exposed to the well (28a-b), and a boss (76) adjacent the opening (78). The boss (76) precludes the wrong terminal of the dry cell (75) from engaging the first connector (74) when the dry cell (75) is inserted into the well (28a-b) in incorrect orientation. A second connector (80) includes a base (81), a first leg (82) resiliently connected to and extending away from the base portion, a second leg (84) resiliently connected to and extending away from the first leg (82), and a third leg (86) resiliently connected to and extending away from the second leg (84) and toward the first leg (82). A display (42) for the instrument (20) has a lens (90) having a substantially transparent substrate with a polyurethane coating. The instrument housing has first and second portions.
