Why does the vertical ascent/descent measurement show different readings even though I am inside and staying in the same room?
Indoors, even small, unnoticeable air currents cause changes in air pressure. For example, if you have a window open at the other end of your house, the air current may affect a room at the other end of the building so little that you don’t notice it, but the sensors of the Observer do. Because the Observer measures ascent and descent based on changes in air pressure, it interprets these changes as vertical movement.
What happens after the 99th logbook?
After recording the 99th logbook, the Observer writes the next logbook over the logbook number 1 (the oldest log) and then continues in numeric order.
What is the maximum capacity of total vertical ascent or descent feet/meters in the logbook history?
The maximum figure that can be shown on the display is 39,999.999 representing feet or meters depending on the unit of measurement set. This should be enough for most users: 39,999.999 meters is roughly
What is the duration readout?
The duration readout tells you how many hours and/or minutes the event recorded into the logbook lasted. For example, if you’re hiking from 1 p.m. to 6 p.m. and the logbook is on during this time, the readout would show a duration of 5:00 hours.
Does the Observer show future trends in weather conditions?
No, the Observer continually accumulates data on barometric pressure and stores the data of last 4 days. The barometric trends of the last 6 hour window is displayed graphically with an arrow in the top field. The Observer does not make forecasts of the
