18. l Sea 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 require 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 The following describes what you should do to give priority to either altitude or temperature e 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 e To give temperature measurement priority remove the watch from your wrist and allow it to hand 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 momentarily affect pressure sensor readings Question How does the barometer work Answer Barometric pressure indicates changes in the atmosphere and by monitoring these changes you can predict the weather with reasonable accuracy Rising atmospheric pressure indicates good weather while falling pressure indicates deterioration weather condi

25. ns This watch features a built in magnetic bearing sensor that detects terrestrial magnetism This means that north indicated by this watch is magnetic north which is somewhat different from true polar north The magnetic north pole is located in northern Canada while the magnetic south pole is in southern Australia Note that the difference between magnetic north and true north as measured with all magnetic compasses tends to be greater as one gets closer to either of the magnetic poles You should also remember that some maps indicate true north instead of magnetic north and so you should make allowances when using such maps with this watch Location e Taking a direction reading when you are near a source of strong magnetism can cause large errors in readings Because of this you should avoid taking direction readings while in the vicinity of the following types of objects permanent magnets magnetic necklaces etc concentrations of metal metal doors lockers etc high tension wires aerial wires household appliances TVs personal computers washing machines freezers etc e Accurate direction readings are impossible while in a train boat air plane etc e Accurate readings are also impossible indoors especially inside ferro concrete structures This is because the metal framework of such structures picks up magnetism from appliances etc Storage e The precision of the bearing sensor may deteriorate if the watch becom
