Abstract
A system and method for rapidly determining ambient temperature in a fluid-analyte meter. The meter includes a housing defining an interior space and an area for receiving a fluid sample. A processor and a first temperature sensor are disposed within the interior space of said the housing. A second temperature sensor is disposed on the housing. One or more processors are configured to determine a first temperature value from temperature data received from the first temperature sensor. The processor(s) are also configured to apply a variable current to a temperature-adjustment source such that the second temperature sensor is adjusted to a predetermined steady-state temperature value different from the first temperature value. The processor(s) are further configured to determine an ambient temperature of an exterior space of the housing based on the applied variable current, pre-determined steady-state temperature, and received first temperature values.
