Abstract
An electrical protection circuitry for a docking station base of a hand held meter and method thereof are disclosed. In the event of a short circuit at a meter interface connector, the protection circuitry removes power at the meter interface connector. Similarly, in the event of an applied voltage outside a specified operating range of the base, the protection circuitry removes power to the meter interface connector. These conditions of the electrical system of the base are monitored regardless whether the meter or the meter's battery is electrically connected to the base. The protection circuitry also provides a visual indication in the event of either the over current and under/over voltage conditions. Additionally, the base is designed to prevent liquid from pooling inside a pocket used to cradle and hold the meter in the base through the use of a drain located at the lowest point in the pocket.
