BAROMETER
This watch uses a pressure sensor to measure air pressure (barometric pressure).
There are two types of measurements:
regular barometric pressure readings and
Barometer Mode barometric pressure readings, which are described below.
· You can calibrate the pressure sensor if you suspect the barometric pressure
reading is incorrect.
Important!
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.
Regular Barometric Pressure Readings
The watch takes regular barometric pressure readings every three hours starting from
midnight each day. The data produced by these readings is used for the graphic
display and barometric pressure graph in the Timekeeping Mode.
· Measurements are taken nine, six, and three seconds before each of the regular
measurement times.
· The watch calculates the average of the three readings, and displays the result.
· Regular barometric pressure readings are different from the readings taken in the
Barometer Mode. Regular barometric pressure readings are used as the data for the
barometric pressure graph and graphic indicator on the Time and Pressure Graph
Screen in the Timekeeping Mode.
To display regular barometric pressure reading graphics
In the Timekeeping Mode, press D to display the Time and Pressure Graph Screen
for the regular barometric pressure readings.
· The barometric pressure graph shows the relative changes between readings for the
past 18 hours. The flashing marker on the right indicates the latest reading.
Example: 10:58pm
Congratulations upon your selection of this CASIO watch. To get the most out of your
purchase, be sure to carefully read this manual and keep it on hand for later reference
when necessary.
Precautions
· This watch is intended for use up to skin diving and snorkeling. It is not designed for
use during scuba diving.
· Never operate the buttons of the watch while underwater or while floating on the
water's surface.
Before Skin Diving/Snorkeling
· Before beginning skin diving or snorkeling, check to make sure that neither of
the following is on the display.
ERROR message (indicating sensor malfunction)
BATT message (indicating low battery power)
· Make sure that the watch is set to the correct time of day.
· Check the glass, case and band for cracks or chips.
· Make sure that the band is fastened securely around your wrist.
While Skin Diving/Snorkeling
· The indicator ERROR on the display may indicate bad data.
· To avoid scratching the watch, take care when skin diving/snorkeling near
rocks or coral.
2413-2
· Each mark on the graphic indicator indicates the relative change between the latest
barometric reading and the one before it.
· The examples on the left indicate that the latest reading is less than the previous
one, while those on the right indicate the latest reading is greater.
Barometric Pressure Graph
Barometric pressure indicates changes in the atmosphere. By monitoring these
changes you can predict the weather with reasonable accuracy. The following shows
how to interpret the data that appears on the barometric pressure graph.
A rising graph generally means improving weather.
A falling graph generally means deteriorating weather.

Note that if there are sudden changes in weather or temperature, the graph line of
past measurements may run off the top or bottom of the display. The entire graph will
become visible once barometric conditions stabilize.
If any of the conditions listed below is present during one of the regular 3-hour
measurements, a blank is inserted into the graph in place of a mark. The next time a
successful reading is obtained (during a regularly scheduled 3-hour measurement),
the current reading is compared with the last successful reading and the
corresponding mark is added to the graph.
· Sensor data error (ERROR flashing on the display)
· Low battery power (BATT flashing on the display)
· Reading outside of measurement range (FULL on the display)
Barometer Mode Screen
A measurement cycle starts after you enter the Barometer Mode, with readings being
taken every three seconds for the first four or five minutes. After that, readings are
taken every minute.
Measurements you take in the Barometer Mode do not affect the barometric pressure
information that appears on the Timekeeping Mode Screens. This means you can use
the Timekeeping Mode Screen to see trends over a longer span, and the Barometer
Mode to find out barometric pressure changes over a shorter term.

To start a barometric pressure measurement cycle
Press C to enter the Barometer Mode. After a few
seconds, the result of the current barometric pressure
reading appears on the display.
· Barometric pressure is displayed in units of 1hPa/mb (or
0.05inHg).
· The mode indicator flashes while a measurement
operation is in progress.
· While a barometric pressure measurement operation is
in progress in the Barometer Mode, press D to stop the
current operation and restart a new measurement cycle.
· Some countries express barometric pressure in units of millibars (mb) instead of
hecto-pascal (hPa). It really makes no difference, because 1hPa = 1mb. In this
manual, we use hPa/mb or hPa (mb).
· You can change the measured barometric pressure unit between hecto-pascals/
millibars (hPa/mb) and inchesHg (inHg). See "To specify the barometric pressure
unit" for details.
· The message FULL appears on the display whenever the barometric pressure
reading is outside the measurable range of 600hPa/mb to 1100hPa/mb (17.70inHg
to 32.45inHg). The barometric pressure value reappears when the barometric
pressure reading returns to the measurable range.
Barometer Mode Graphic Indicator
In the Barometer Mode, the graphic indicator shows the
current barometric pressure. Segments are darkened in
the graphic indicator from the left (lower pressure) to the
right (higher pressure).
· In the range of 600 to 950hPa/mb each rise of 35hPa/
mb causes one more segment to be darkened. In the
range of 951 to 1045hPa/mb, each rise of 5hPa/mb
causes one more segment to be darkened. All segments
are darkened when the barometric pressure is 1046hPa/
mb or greater.
· When the barometric pressure unit is set to inHg, the
watch actually measures in hPa/mb units and then
converts to inHg. Because of this, the graphic indicator
will show the hPa/mb value before switching to the
corresponding inHg value.
Graphic indicator
(Indicates 1018hPa/mb)
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 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.
Important!
· This watch estimates altitude based on air pressure.This means that altitude
readings for the same location may vary if air pressure changes.
· 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.
· Note that the following conditions will prevent you from obtaining accurate readings:
When air pressure changes because of changes in the weather
Extreme temperature changes
When the watch itself is subjected to strong impact
· In order to avoid measurement problems caused by differences in the watch's
temperature, be sure to wear the watch so that it comes into direct contact with your
skin.
· Do not use this watch for measuring altitude in applications that demand
professional or industrial level precision.
How the Altimeter Works
The watch measures
relative altitudes in relation to a reference altitude set by you.
You can set a reference altitude using zero reset, or by specifying an altitude value
from a map, sign post, etc.
· After you set the reference altitude, the watch adjusts its air pressure to altitude
conversion calculation accordingly.
Setting a Reference Altitude Value
With this method, you can specify a current altitude value you obtain from a map or
signpost. Then the watch measures altitude relative to the value you set.
· When mountain climbing, you can set the reference value in accordance with a
marker along the way or altitude information from a map.
· 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.
To set a reference altitude value
1. Press C to enter the Altimeter Mode, and wait for a few seconds until the current
altitude value appears on the display.
2. Hold down A until the current altitude value starts to flash. This indicates the
reference altitude setting screen.
3. Use D (+) and B () to change the displayed value in 5-meter (20-foot)
increments.
· You can set a reference altitude value in the range of 0 to 4000 meters (0 to
13120 feet).
4. Press A to exit the setting screen.
· After you press A, the numbers on the display indicate that the watch is making
internal adjustments. This operation takes about nine seconds. Once adjustments
are finished, the altitude display appears.
Graphic indicator
(Indicates 1550m)
Reference Altitude Zero Reset
With zero reset, you can set the reference altitude to zero. The watch then measures
altitude relative to zero.
· 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.
· Before beginning a climb up a mountain, you could set the reference altitude to 0m
at the foot of the mountain. This makes it possible to determine the difference in
altitude between the reference point and your destination.
To zero reset the reference altitude
1. Press C to enter the Altimeter Mode, and wait for a few seconds until the current
altitude value appears on the display.
2. Hold down A until the current altitude value starts to flash. This indicates the
reference altitude setting screen.
3. Press B and D at the same time to change the displayed value to zero.
4. Press A to exit the setting screen.
· After you press A, the numbers on the display indicate that the watch is making
internal adjustments. This operation takes about nine seconds. Once adjustments
are finished, the altitude display appears.
Using the Altimeter Mode
A measurement cycle starts after you enter the Altimeter Mode, with readings being
taken every three seconds for the first four or five minutes. After that, readings are
taken every minute.
· Altitude is displayed in 5-meter (20-foot) units.
· The mode indicator flashes while a measurement
operation is in progress.
· While an altitude measurement operation is in progress
in the Altimeter Mode, press D to stop the current
operation and restart a new measurement cycle.
· The measured altitude may be a negative value in
cases where there is a reference altitude value set or
because of certain atmospheric conditions.
· You can change the unit of measurement for the
displayed altitude values between meters (M) and feet
(F). See "To specify the altitude unit".

· In the Altimeter Mode, the graphic indicator shows the current altitude. Segments
are darkened in the graphic indicator from the left (lower altitude) to the right (higher
altitude). In the range of 5 to 1000 meters (20 to 4000 feet), each increase of 45
meters (180 feet) causes one more segment to be darkened. In the range of 1005 to
2800 meters (4020 to 9400 feet), each increase of 195 meters (580 feet) causes
one more segment to be darkened. All segments are darkened when the altitude is
2805 meters (9420 feet) or greater.

Altimeter Mode
How does the altimeter work?
Generally, air pressure and temperature decrease as altitude increases. Under its
factory defaut setting, this watch bases its altitude measurements on International
Standard Atmosphere (ISA) values stipulated by the International Civil Aviation
Organization (ICAO). These values define relationships between altitude, air pressure,
and temperature.

Temperature
Depth Gauge Mode
About depth and water pressure
Water pressure increases with depth. In the case of sea water (specific
gravity=1.025), water pressure increases by 1 ATM (1.03 kg/cm
2) with each 10 meters
(33 feet) of depth.
This watch makes use of the relationship between pressure and depth, using a
pressure sensor to calculate the water pressure and then converting this data into
depth readings.
Depth Gauge Measurement Precautions
You cannot exit the Depth Gauge Mode or change the measurement unit setting while
the depth reading on the display is any value other than zero. This is to prevent
accidental switching from the Depth Gauge Mode while underwater.
Automatic Zero Depth Reset
The initial displayed depth reading is zero whenever you enter the Depth Gauge
Mode, even if you are underwater. Because of this, you should enter the Depth Gauge
Mode just before starting your dive. Do not enter the Depth Gauge Mode while
underwater.
Manual Zero Depth Reset
In some cases, such as when the sensor is exposed to
wide changes in temperature, the display may show a
depth of greater than 1.0 meter (3 feet) even when you
are on the surface. In this case, hold down C and D at
the same time to reset the depth reading to zero.
Backlight Precautions
The backlight uses an EL (electro-luminescent) panel that causes the entire display to
glow for easy reading in the dark. In any mode (except for the Stopwatch Mode),
press B to illuminate the display for about one second.
· The backlight does not turn on if you press B while a setting screen is on the
display.
· The electro-luminescent panel that provides illumination loses power after very long
use.
· The watch may emit an audible sound whenever the display is illuminated. This is
due to vibration of the EL panel used for illumination, and does not indicate
malfunction.
· The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
· The backlight turns off whenever an alarm sounds.
· The backlight remains lit for about one second from the point you press the button,
even if it is already lit when you press the button. If you keep the button depressed
for one second or more, the backlight turns off.
· Frequent use of the backlight shortens battery life.
Calibrating a Barometric Pressure Value and Specifying a Measurement
Unit
The pressure sensor of this watch is calibrated at the factory before shipment and
further adjustment is normally not required. If you notice serious errors in the
barometric pressure readings produced by the watch, you can calibrate the sensor to
correct the errors.
Important!
Incorrectly calibrating the barometric pressure sensor can result in incorrect readings.
Before performing the calibration procedure, compare the readings produced by the
watch with those of another reliable and accurate barometer.
To calibrate the barometric pressure value
1. Press C to enter the Barometer Mode.
2. After the result of the current measurement appears,
hold down A until the barometric pressure value starts
to flash. This indicates the barometric value setting
screen.
3. Use D (+) and B () to change the value in 1hPa/mb
(0.05inHg) increments.
· You can calibrate the barometric pressure value in the
range of 600 to 1100hPa/mb (17.70 inHg to
32.45inHg).
