The Readings box shows the highest, lowest and average of the readings. In this example, the highest reading was 243, the lowest was 54, and the average of all readings was 126.
The Target Range box shows how the readings fall in relation to the target range your doctor has set for you (high and low targets are set in the 'setup' screen on the PDA). In this example, the target range is from 60 to 130. One reading was below the target range, 37 were above and 61 fell within the range.
