The horizontal axis of the graph represents time. The rightmost column is the newest temperature value in memory, while the leftmost column is the temperature value stored approximately 17 hours ago (1 dot = 1 hour). The vertical axis of the graph represents the relative change from one hour to the next.
•When the relative change from one hour to the next exceeds +10.0°C (+18.0°F), the dot at the highest point for the applicable hour flashes.
•When the relative change from one hour to the next exceeds
•If a measurement error occurs for some reason, only a single the dot in the center column will be displayed.

Recalling Temperature Data
The measurements the watch takes at the top and the bottom of each hour are stored in memory automatically. Memory can hold up to 50 measurement records. You can use the Temperature Data Recall Mode to recall memory data when you need it.
•Each temperature data record has a number. The newest data record is number 01, while the oldest data record is the one with the highest number.
•When there are already 50 records in memory, storage of a new temperature reading causes the oldest record (record number 50) to be deleted automatically to make room for the new data. The new data is assigned record number 1, and all of the numbers of all the other records (01 to 49) are incremented by 1 (becoming 02 through 50).
