Method of ensuring date and time on a test meter is accurate

摘要

A method of operating a glucose test meter is provided. The method can be achieved by storing a plurality of glucose readings to a first memory of the test meter, each of the glucose readings having a time stamp and an order index, the time stamp comprising a date and a time when the glucose reading was performed, the order index indicating an order in which the plurality of glucose readings was saved to the first memory; determining whether successively saved glucose readings have time stamps in chronological order consistent with the order index; and indicating that the date and the time setting in the test meter is incorrect if there are successively saved glucose readings having time stamps inconsistent with the order index.
