THERMOMETER/BAROMETER
(ABT, WRKS)
Rotate the crown until you get to THERMOMETER/BAROMETER mode.
Convenience is quite abundant these days and your new watch is no exception.
Both the thermometer and barometer are conveniently self-calibrating. Temperature
readings are taken every minute and barometric readings are taken on the hour. Upon
entry into THERMOMETER/BAROMETER mode, new initial barometric readings are
immediately taken.
During normal operation, the display will show the following (see Figure 2):
Line 1: Current temperature.
Line 2: Difference between most recent hourly barometric reading and the one taken an
hour earlier.
Line 3: Barometric reading.
Line 4: Current time.
BONUS CULTURAL CONVENIENCE: Data can be viewed in either English (Hg) or metric (mb),
and also Fahrenheit (F) or Celsius (C). To learn how to switch between the two, see Setting
the Format.
Reviewing Barometric Readings
Barometers are neat — don't let anyone tell you differently. They sort of let you see into
the future. The basic barometric rules of thumb state that if the pressure is on the rise,
good weather is on its way; if it’s down, a storm's coming — useful info if you’re
wondering about surf conditions, impending snowy or rainy weather, or if
you're planning what you hope to be a sunny-day picnic.
NOTICE: Your watch stores the two most recent hourly readings
without complaint, as well as readings for 12:00 AM, 4:00 AM,
8:00 AM, 12:00 PM, 4:00 PM, and 8:00 PM. The current
display will show the difference between the
two most recent
hourly readings. Simple, right?
A. To review old readings, you should pull the crown
out to Position 3. That's when RECALL will appear and the
watch will display the earliest four-hour interval reading (in Line 3)
along with the difference between that and the reading from four hours
earlier. So you're not totally confused, the time of the reading will be
displayed at the bottom (Line 4).
B. To look through all the stored readings, rotate the crown. You should have that
wired by now. Differential and time will change according to changes in stored data,
and you'll be able to literally track the progress of the weather as it progresses or
digresses — depending on your tastes.
DID WE MENTION? If the watch hasn't accumulated six prior barometric readings at the
aforementioned four-hour intervals, the words NO DATA will appear when crown is pulled out
to Position 3. Once again, it's nothing personal.
ALTIMETER
(ABT, WRKS)
Rotate the crown until you get to ALTIMETER mode. Your i•CONTROL® Setting Systems watch
uses its ability to measure barometric pressure to estimate altitude readings. Because baro-
metric pressure is always changing, it's recommended that you recalibrate the altimeter
often — at least before activities in which you plan to use it frequently (i.e., snowboarding,
skiing, climbing, rappelling, etc.).
ADDITIONAL ABILITY NOTE: Altitude can be viewed in either English (ft.) or metric
(m.). To learn how to switch between the two, see Setting the Format.
Calibrating the Altimeter
A. Pull the crown out to Position 3 while in THERMOMETER/
ALTIMETER mode. CALIBR ALTI appears, followed by SET
ALTI, and what the watch believes in all honesty to be
the current altitude.
