USING THE ST-4000 ALTIMETER AND BAROMETER (ALTITUDE)
The ST-4000 shows altitude below or above sea level from -4,000 feet to
+30,000 feet in 5-foot increments.
ALTIMETER AND BAROMETER DETAILS
How the Altimeter Works
The ST-4000 measures altitude by detecting differences in air
pressure and displaying this information as altitude above sea level.
The ST-4000 works the same way an aircraft altimeter does.
Moving Barometer
There are two kinds of barometers: fixed location and moving location.
Moving barometers are designed to be used at varying elevations.
The ST-4000, like an aircraft altimeter, contains a moving location barometer. Its reading does not move until you set it by adjusting the
altitude in the altimeter display.
- 5 -
Altitude Offset
A weather change will produce a change in barometric pressure that
causes an offset in the displayed altitude from the actual altitude. This offset
is consistent at any altitude, so, if you start a hike with the altitude reading
50 feet too high, it will read 50 feet too high at any elevation on your hike.
You remove the offset by adjusting the altitude.
When to Adjust Altitude
Adjust the altitude when you want precise altitude readings, such as before
hiking or climbing, or when you want to update the Sea Level Barometer.
Adjust at a known altitude such as at the sea side, a marked summit or pass,
or a location with an altitude reference on a map such as a lake. Home or
office make convenient adjustment points after learning their elevations
from a topographic map.
Adjust once a day when hiking, climbing, or when following weather patterns.
You can also adjust altitude in the barometer. Adjust display by entering a
current, local barometer reading from a weather report or airport weather
service. When you enter the barometer reading, the altitude is also adjusted
in the altimeter.
- 6 -
Effects of Atmospheric Pressure Changes
A change in atmospheric pressure will make the displayed altitude different
from the known altitude of a landmark. The ST-4000 can be
adjusted so that it displays the same altitude as the landmark. Minor atmospheric pressure changes may cause the displayed altitude to vary from the
actual altitude by 50 feet. With the arrival or departure of a weather front,
displayed altitude can change 100 to 200 feet, and a storm can cause a
change of more than 200 feet. Wind, rain, snow, and humidity do not affect
altimeter readings.
Barometer-Altimeter Synchronization
Synchronization (the relation between altitude and sea level barometer) is
set at the factory. To ensure barometer accuracy you can check it after a
year or two and correct minor drift if necessary. You must know your current
altitude and must get the current sea level barometer from a local airport or
weather broadcast to make this adjustment.
You can also synchronize the thermometer if it reads consistently high or
low over a range of temperatures.

Thermometer Accuracy
The ST-4000 measures the ambient air temperature with a sensor inside its
case. When the watch is worn against your skin, temperature readings will
be affected significantly. Direct sunlight can also cause the
ST-4000 to give high readings. For accurate readings, remove the watch
from your wrist and place away from direct sunlight.
Display
The Altimeter and Thermometer revert to the Clock 10 minutes after the last
time a button is pressed.
NOTE: The analog and digital movements of this watch
operate independently. Please set each individually to
ensure they are kept in sync.
