Barometer/Thermometer

This watch uses a pressure sensor to measure air pressure (barometric pressure) and a temperature sensor to measure temperature.

• You can calibrate the temperature sensor and the pressure sensor if you suspect that readings are incorrect.

To take barometric pressure and temperature readings

Pressing B in the the Timekeeping Mode or in the Altimeter Mode enters the Barometer/Thermometer Mode and automatically starts taking barometric pressure and temperature measurements.

a measured barometric pressure falls outside the range of 600 hPa to 1100 hPa (17.70 inHg to 32.45 inHg). The barometric pressure value will be displayed again as soon as the measured barometric pressure is within the allowable range.

• Temperature is displayed in units of 0.1°C (or 0.2°F).

• The displayed temperature value changes to

measured temperature falls outside the range of –10.0°C to 60.0°C (14.0°F to 140.0°F). The temperature value will be displayed again as soon as the measured temperature is within the allowable range.

• Some countries refer to the barometric pressure unit hecto-pascal (hPa) as millibars (mb). It really makes no difference, because 1hPa = 1mb.

• See “Barometer and Thermometer Precautions” for important precautions.

Barometric Pressure History Graph

Barometric pressure indicates changes in the atmosphere. By monitoring these changes you can predict the weather with reasonable accuracy. The barometric pressure history graph contains points that show you the changes in barometric pressure readings taken by the watch for up to the last 18 hours. The rightmost point on the graph is the latest reading. The relative positions of the points on the graph indicate whether barometric pressure is rising, falling, or holding relatively steady.

• Though you can configure the watch to display barometric pressure in units of hPa or inHg, the history graph always uses hPa. This means that the points plotted on the history graph are based on ±3hPa changes in barometric pressure.

• No point is plotted on the graph whenever a measurement operation fails due to sensor malfunction, low battery power, or any other reason.

• Barometric pressure measurement is disabled whenever you are performing depth measurement in the Depth Gauge Mode. Because of this, the graph plots of barometric pressure measurement operations that occur during a depth measurement are skipped.

The following shows how to interpret the data that appears on the barometric pressure history graph.

A rising graph generally means improving weather.

A falling graph generally means deteriorating weather.

About Barometric and Temperature Measurements

• Barometric pressure and temperature measurement operations are performed as soon as you enter the Barometer/Thermometer Mode. After that, barometric pressure and temperature measurements are taken every five seconds for the first two or three minutes.

• The barometric pressure reading.

• The barometer automatically takes measurements every three hours (starting from midnight), regardless of what mode you are in. The results of these measurements are used for plotting points on the barometric pressure history graph.

• You can also perform a barometric pressure and temperature measurement at any time by pressing B in the Barometer/Thermometer Mode.

Barometer and Thermometer Precautions

• The pressure sensor built into this watch measures changes in air pressure, which you can then apply to your own weather predictions. It is not intended for use as a precision instrument in official weather prediction or reporting applications.

• Sudden temperature changes can affect pressure sensor readings.

• 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.

• You can select either hectopascals (hPa) or inchesHg (inHg) as the display unit for the measured barometric pressure. See “Changing the Barometric Pressure and Temperature Units” for details.

• You can select either Celsius (°C) or Fahrenheit (°F) as the display unit for the measured temperature value. See “Changing the Barometric Pressure and Temperature Units” for details.

Altimeter

A built-in altimeter uses a pressure sensor to detect the current air pressure, which is then used to estimate the current altitude. The watch is preprogrammed with ISA (International Standard Atmosphere) preset values, which are used to convert air pressure readings to altitude values. If you preset a reference altitude, the watch will also calculate the current relative altitude based on your preset value.

Important!

• This watch estimates altitude based on air pressure. This means that altitude readings for the same location may vary if air pressure changes.

• This watch employs a semiconductor pressure sensor, which is affected by temperature changes. Make sure that the watch is not being exposed to temperature changes while you are taking altitude measurements.

• To avoid the effect of sudden temperature changes on measurement, wear the watch so it is in direct contact with your wrist during measurement.

• Do not rely upon this watch for altitude measurements or perform button operations while engaging in sports where there are sudden altitude changes, while sky diving, hang gliding, or paragliding, or while riding a gyrocopter, glider, or any other aircraft.

• Remember that the air inside of a commercial aircraft is pressurized. Because of this, the readings produced by this watch will not match the altitude readings announced or indicated by the flight crew.

How the Altimeter Works

With the Preset Values (No Reference Altitude)

• The watch measures the air pressure at your current location and uses the built-in ISA values to convert it to the equivalent altitude.

With a Reference Altitude

• If you set a reference altitude, the watch uses that value when calculating altitude based on air pressure.

• To determine the height of a tall building, set the reference altitude to 0 on the ground floor. Note, however, that you may not be able to get a good reading if the building is pressurized or air-conditioned.

• When mountain climbing, you can set the reference value in accordance with a marker along the way or altitude information from a map. After you do this, the altitude readings produced by the watch will be more accurate than they would without a reference altitude.

Temperature

Altitude

• Pressing D causes the measurement operation to restart from the

beginning of the cycle described above.

• Altitude is displayed in units of 5 meters (20 feet).

• The measurement range for altitude is –700 to 4,000 meters (–2,300 to

13,120 feet). The display range for altitude (include values based on the reference altitude) is –4,000 to 4,000 meters (–13,120 to 13,120 feet).

• An altitude reading may result in a negative value in cases when you have a reference altitude value set or because of certain atmospheric conditions.

• The displayed altitude value changes to measured altitude falls outside the measurement range. The altitude value will be displayed again as soon as the measured altitude is within the allowable range.

• You can change the unit of measurement for the displayed altitude values between meters (m) and feet (ft). See “To change the altitude unit”.

Setting a Reference Altitude

After you set a reference altitude, the watch adjusts its air-pressure-to-altitude conversion calculation accordingly. The altitude measurements produced by this watch are subject to error caused by changes in air pressure. Because of this, we recommend that you update the reference altitude whenever one is available during your climb.

Barometer/Thermometer Mode enters the Altimeter Mode and automatically starts altitude measurement.

• It can take up to four or five seconds for the altitude reading to appear after you enter the Altimeter Mode.

• The Altimeter Mode screen also displays the current temperature. See “Barometer/ Thermometer” for more information.

• During the first two or three minutes after entering the Altimeter Mode, the flashes on the display and measurements are taken every five seconds. After that, the indicator stops flashing and remains on the display as measurements are taken every two minutes.

goes blank. This is the setting screen.

• If OFF or the current reference altitude value does not appear at this

time, press A to return to the Altimeter Mode screen, and perform step 1 again.

2. Press D (+) or B (–) to change the current reference altitude value by 5

meters (or 20 feet).

• You can set the reference altitude within the range of –4,000 to 4,000 meters (–13,120 to 13,120 feet).

• Pressing D and B at the same time returns to altitude), so the watch performs air pressure to altitude conversions based on preset data only.

3. Press A to exit the setting screen.

• Wait for four or five seconds before performing step 2, below. If you don’t wait, there is the chance of setting value error.

• If the display went blank in step 1, the current reference value will appear (flashing) on the display after the four or five seconds pass.

Depth Gauge

The pressure sensor of the watch can also be used to perform underwater depth measurement while skin diving or snorkeling. Depth readings are taken every three seconds, and displayed as a value up to 30 meters (98 feet). You can store the data of your last dive in log memory, including total time submerged, maximum depth, and water temperature at the maximum depth attained during your dive. You can view the log data of your last dive before beginning a new dive.

Important!

• Never use this watch to measure depth while scuba diving.

• This watch is designed to start depth measurement and record data in

memory after a depth of 1 meter (4 feet) is reached. Because of this, the explanations in this User’s Guide uses the term “submerged” to refer to any depth deeper than 1 meter, and the “on the surface” to refer to any depth shallower than 1 meter.

• Leaving the watch in the Depth Gauge Mode while not in the water consumes battery power. Exit the Depth Gauge Mode whenever you are not using it.

• The measurement unit selected in the Altimeter Mode is also used in the Depth Gauge Mode.

What is “a dive”?

A dive starts when you pass a depth of one meter (about four feet) while the watch is in the Depth Gauge Mode. The dive ends when you are on the surface and exit the Depth Gauge Mode. A dive does not end if you surface but do not exit the Depth Gauge Mode.

Enter the Depth Gauge Mode.

• Remember that the term “dive” as used in this manual refers to skin diving or snorkeling only.

• The watch will start depth measurement automatically when the sensor detects that your depth exceeds one meter (about four feet).

• Depth measurement stops automatically whenever your depth becomes less than one meter (four feet).

• Depth measurement restarts whenever you re-submerge past one meter (four feet). All data that is measured between the start of the dive and the end of the dive is treated as part of the same dive, no matter how many times you surface during the dive.
