Some countries refer to the barometric pressure unit hecto-pascal (hPa) as
millibars (mb). It really makes no difference, because 1hPa = 1mb. In this
manual, we use hPa/mb or hPa (mb).
Barometric Pressure Graph
Barometric pressure indicates changes in the atmosphere. By monitoring
these changes you can predict the weather with reasonable accuracy. The
barometric pressure graph shows the barometric readings for the past 26
hours. The flashing point on the right of the display is the point for the newest
measurement. Note that pressure graph readings are relative to the newest
measurement point. One dot above the newest point is plus 1hPa(mb)/
0.05inHg, while one dot below is minus 1hPa(mb)/0.05inHg. The following
shows how to interpret the data that appears on the barometric pressure
graph.

The barometer automatically takes measurements every two hours
(starting from midnight), regardless of what mode you are in. The results of
these measurements are used for the barometric pressure graph.
Direction bezel
•
You can adjust the rotary direction bezel so
that the “N” is aligned with the magnetic
north pointer. This correctly aligns all of the
markings on the bezel.
•
You can also perform a barometric pressure and temperature
measurement at any time by pressing
C
in the Barometer/Thermometer
Mode.
•
The Digital Compass operation is
automatically interrupted whenever an
alarm (Daily Alarm or Hourly Time Signal)
sounds. If this happens, start the Digital
Compass operation again from the
beginning.
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.
•
See “Digital Compass Precautions” for other
important information about taking direction
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 off
all moisture from the case. It takes approximately 20 to 30 minutes for the
case of the watch to reach the actual surrounding temperature.
BAROMETER/THERMOMETER
This watch uses a pressure sensor to measure air pressure (barometric
pressure) and a temperature sensor to measure a temperature.
•
•
You can change the measured barometric pressure unit between hecto-
pascals/millibars (hPa/mb) and inchesHg (inHg). See “Changing the
Barometric Pressure and Temperature Units” for details.
You can calibrate the temperature sensor and the pressure sensor if you
suspect that readings are incorrect.
•
You can change the measured temperature value displayed by this watch
between Celsius (
°
C) and Fahrenheit (
°
F). See “Changing the Barometric
Pressure and Temperature Units”.

ALTIMETER
Memory measurements
Memory measurements are taken independently of Altimeter Mode
measurements and stored directly into memory (along with the date and time
of the measurement) for later recall. There are two types of memory
measurements: “Auto measurements” and “Manual measurements”.
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 pre-
programmed 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. Altimeter functions also include data
storage memory and an altitude alarm.
Auto measurements
With Auto measurement, the watch continuously performs measurements
whenever the minutes in the Timekeeping Mode reach 00, 15, 30, or 45, until
you switch Auto measurements off. The watch continues to take
measurements regardless of whether or not you change modes, so you can
keep a running log of altitude changes automatically.
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. When taking altitude measurements, be sure to do
so while ensuring that the watch is not exposed to temperature changes.
Manual measurements
You can use the manual procedure to take a reading anytime you want to
store your current altitude data into memory for later recall. Manual memory
measurements can be performed only while the watch is in the Altimeter
Mode.
•
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.
•
Do not use this watch for measuring altitude in applications that demand
professional or industrial level precision.
Selecting Auto or Manual Measurement
Use the following procedure to switch between Auto or Manual measurement.
Note that you cannot perform this operation while a preset Auto measurement
is already in progress.
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.
To select Auto or Manual measurement
1. In the Altimeter Mode, hold down
A
until
the display clears. After four or five
seconds, either
OFF
or the current
reference altitude value (if set) will start to
flash, which indicates the setting screen.
2. Press
D
twice to move the flashing to the
memory measurement setting (
AUTO
or
MANUAL
).
With a Reference Altitude
•
After you set the reference altitude, the watch adjusts its air pressure to
altitude conversion calculation accordingly.
•
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.
•
Press
D
to move the flashing in the sequence shown below.
Reference
Altitude
•
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.

indicator is shown on the display.
•
•
The measurement range for altitude is –700 to 10,000 meters (–2,300 to
32,800 feet).
•
The measured altitude may be a negative value in cases where there is a
reference altitude value set or because of certain atmospheric conditions.
•
The displayed altitude value changes to
xxxx
meters (or feet) if a
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.
If it is not, use the procedure under “To select Auto or Manual
measurement” to select Manual measurement.
2. In the Altimeter Mode, hold down
E
until the watch emits a short beep,
indicating that a measurement is taken.
•
•
You can change the unit of measurement for the displayed altitude values
between meters (m) and feet (ft). See “To change the Altitude Units”.
Repeat step 2 whenever you want to take a reading.
•
Button operation becomes impossible during the four or five seconds
that it takes to complete a measurement. Normal operation will return
once the operation is finished.
About Altitude Measurements
There are two types of altitude measurements: those for displayed data
(Altimeter Mode measurements) and those for memory data (Memory
measurements).
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.
Altimeter Mode measurement
This type of measurement is performed only when the watch is in the
Altimeter Mode. As soon as you enter the Altimeter Mode, measurements are
taken every five seconds for the first three minutes. After that, measurements
are taken every two minutes.
•
The
ALTI
indicator flashes on the display while a measurement is in progress.
To use Auto measurement
1. Confirm that the
AUTO
indicator is shown on the display.
•
•
•
Altitude is displayed in units of 5 meters (20 feet).
2271-4
To set a reference altitude
1. In the Altimeter Mode, hold down
A
until
the display clears. After four or five
seconds, either
OFF
or the current
reference altitude value (if set) will start to
flash, which indicates the setting screen.
•
OFF
indicates no reference altitude.
2. Press
E
to increase the current reference
altitude value by 5 meters (or 20 feet) or
B
to decrease it.
Auto Measurement Records
•
Performing an Auto measurement produces a set of records of all the
measurements taken during the Auto measurement session. Since Auto
measurement produces four altitude readings per hour (at 00, 15, 30, and
45 minutes of each hour) leaving Auto measurement turned on for two
hours would result in a set of eight records.
•
The following shows how the records that make up an Auto measurement
set appear when you recall them.

About the Altitude Alarm
The altitude alarm sounds for about five seconds whenever the current
altitude matches a preset value. You can press any button to stop the alarm
after it starts to sound.
•
The altitude graph separates the maximum and minimum altitude readings
by nine display dots. Other readings are shown relative to the maximum
and minimum.
•
Note that Auto measurement records are always treated as a set. This
means that deleting one record in a set deletes the entire set.
Example
If you set the altitude alarm at 130 meters, it sounds when you pass the 130-
meter mark on your way up and on your way back down.
Manual Measurement Records
•
Performing a Manual measurement produces a single record. The
illustration below shows how a Manual measurement record appears when
you recall it.
To set the altitude alarm

Note
•
50 records are enough to store 12 hours and 15 minutes of Auto
measurement data (if you do not take any Manual readings during that
time).
Memory Data Management
Each altitude record includes an altitude reading, plus the month, day, hour,
and minutes the measurement was taken. Records are displayed in the order
they were saved.
Memory can hold up 50 records. You can store 50 Auto measurement
records, 50 Manual measurement records, or any mixed combination of Auto
and Manual measurement records. In addition, there are two extra records
that show the highest (max) and lowest (min) altitude values, from among the
displayed data (Altimeter Mode measurements) and memory data (Memory
measurements).
The following example illustrates how data would be arranged in memory after
you perform one Auto measurement (Auto 1), two Manual measurements
(Manual 1, Manual 2), and then one Auto measurement (Auto 2).
Important!
•
Further Auto or Manual measurements become impossible whenever
memory is full. The message
FULL
on the display indicates that memory
is full. Always check the amount of memory remaining before starting
memory measurements, and delete records if necessary.
Measurement records are stored in memory even if an error occurs during
the measurement. For details on errors, see “Warning Indicators”.
