A test meter and related method for monitoring the condition of a backlight battery of the meter in which the meter includes a housing, controller, display with backlight and a battery monitoring circuit. An off-time of the meter is measured and compared to a predetermined recovery time of the backlight battery. If the off-time of the meter is greater than the predetermined recovery time of the backlight battery, a voltage of the backlight battery is measured at a predetermined time after energizing the backlight and compared to a first predetermined voltage in excess of a threshold voltage of the backlight battery. If the measured voltage is less than the first predetermined voltage, the measured voltage is compared to a second predetermined voltage between the first predetermined voltage and the threshold voltage. A battery depletion warning is displayed if the measured voltage is less than the second predetermined voltage.

Portable test meter with backlight battery depletion monitoring

An analyte measurement system includes a processor connected to a biosensor providing analyte data corresponding to an analyte level of a fluid sample. A user interface provides a menu of functions to a user and successively receives a plurality of menu choices, which the processor records. A storage device holds data defining a first action criterion. The processor compares the menu choices to the first action criterion. When the stored menu choices satisfy the first action criterion, the processor can automatically add a first additional function to the menu of functions, or can automatically presents a reward token via the user interface. The system can also include a housing holding the user interface, the storage device, and the processor. Methods are also disclosed.
