Precautions Concerning Simultaneous Measurement of
Altitude and Temperature
Though you can perform altitude and temperature measurements at the same time,
you should remember that each of these measurements requires different conditions
for best results. With temperature measurement, it is best to remove the watch from
your wrist in order to eliminate the effects of body heat. In the case of altitude
measurement, on the other hand, it is better to leave the watch on your wrist, because
doing so keeps the watch at a constant temperature, which contributes to more
accurate altitude measurements.
• To give altitude measurement priority, leave the watch on your wrist or in any other
location where the temperature of the watch is kept constant.
• To give temperature measurement priority, remove the watch from your wrist and
allow it to hang freely from your bag or in another location where it is not exposed
to direct sunlight. Note that removing the watch from your wrist can affect pressure
sensor readings momentarily.
