2.Simultaneously press and hold [+] and [-] for about 2 seconds.

3.Simultaneously press again until the desired units have been selected.

ABOUT THE PRESSURE CHANGE GRAPH

The EB833 can display barometric pressure levels at intervals for the past 12 hours. Each vertical bar on the Pressure Change Graph represents a 2-hour time period. Each horizontal line represents pressure change equal to + / - 2 mb/hPa.

( 2 HOURS PER COLUMN )

An upward or downward direction of the vertical bars may illustrate a changing pressure trend. Subsequently, this may indicate changes in weather conditions. However, as stated previously, caution needs to be taken when attempting to predict weather forecasts.

PRESSURE HISTORY DISPLAY

Barometric pressure readings can also be displayed numerically.

1.Enter Barometric History Display.

2.Press [+] or [-] to display the corresponding barometric pressure for the specified time period.

NOTES ON THE BAROMETER FUNCTIONS

Barometer readings may be affected by a change in altitude.

The unit cannot distinguish between a change in air pressure caused by weather patterns or by a change in altitude. However, accurate functioning of the unit can be maintained by following a few simple steps.

To ensure that accurate barometric readings are maintained:

When the unit is stationed at the same elevation for extended periods, it is advised to keep the unit in Barometer Mode.

In addition to maximizing the weather forecasting capabilities the unit requires less power to function. Subsequently battery life may be extended.
