Designed to be durable, this unit is constructed for rugged outdoor use. The EB833 has three primary functions. 1. Altimeter - Functions related to altitude measurement. 2. Barometer and Weather Forecast Device - Functions related to weather forecasts and atmospheric pressure. 3. Clock, Calendar, and Count-Up Timer - Functions related to time, date, and count-up timer. An altimeter, the EB833 will measure and display current altitude readings, changes between two elevations, and maximum and minimum altitudes. The unit stores altitude data and can indicate changes in altitude for a 12-hour period or calculates the total accumulation of elevation ascents over a given period of time. In addition, the user can set an altitude alarm that will activate when specified elevations are reached. The EB833 is also a barometer. It measures and displays current pressure readings, and provides a barometric history and a bar graph showing barometric changes over a 12-hour period. EB833(EN3) 2 A weather forecast device, the EB833 uses barometric information to make forecasts as sunny, slightly cloudy, cloudy, and rainy. It also has a built-in thermometer. As a timepiece, this unit functions as a clock / calendar, daily alarm, and count-up timer. To optimize the usefulness of this device, be sure to read this instruction manual carefully before use, and keep it handy for future reference.
