Thermometer
This watch uses a temperature sensor to measure temperature. A reading is taken
during each even-numbered minute, and the result of the last reading is displayed on
the thermometer screen.
The watch also takes separate readings and stores them in memory for display in the
temperature tendency graph, which can be viewed in the Timekeeping Mode.
Measured temperature values are stored in memory for later recall when you need
them.

You can select either Celsius (

screen. See “To specify the temperature display unit” for more information.
•
The thermometer screen displays temperature values in 0.1

The display range of the thermometer screen is –10.0

•
You can calibrate the temperature sensor if you feel that the displayed temperature
values are not correct. See “Temperature Sensor Calibration” for more information.
Important!
•
Temperature measurements are affected by your body temperature (while you are
wearing the watch), direct sunlight, and moisture. To achieve a more accurate
temperature measurement, remove the watch from your wrist, place it in a well
ventilated location out of direct sunlight, and wipe all moisture from the case. It takes
approximately 20 to 30 minutes for the case of the watch to reach the actual
surrounding temperature.
Temperature Tendency Graph
The watch also takes temperature readings at the top and the bottom of each hour
and stores the results in memory for display on the temperature tendency graph.
Depending on the current Timekeeping Mode time, the temperature tendency graph
shows either the top of the hour measurements or the bottom of the hour
measurements for the past 17 hours.
From the top of each hour to the 29th minute, past top of the hour readings are shown
in the graph. From the bottom of each hour to the 59th minute, past bottom of the hour
readings are shown in the graph.
Temperature tendency graph contents are updated every 30 minutes.

Error
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 e10.0°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 –10.0°C (–18.0°F),
there is no dot in the applicable hour’s column.
•
If a measurement error occurs for some reason, only a single 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.
•
Temperature data records are assigned numbers automatically starting from 01.
•
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).
To recall temperature records
1. In the Timekeeping Mode, press
C
to enter the
Temperature Data Recall Mode.
•
This displays the newest record currently in memory.
2. Use
D
(+) to scroll through the records.
•
Pressing
D
while the oldest record is displayed will
scroll to the newest record.
•
If a temperature measurement operation is performed
while a record is displayed, the displayed record’s
number will be incremented by 1.
•
If an error occurs during temperature measurement,
--

will be shown for the temperature value in the
corresponding record.
