Entering Barometric Pressure
Because atmospheric pressure varies with both altitude and local weather con-
ditions, you must enter the current barometric pressure for your location. Wait
at least one hour after powering the GroWeather (to allow the circuit a chance
to stabilize) before you enter barometric pressure. Once the barometric pres-
sure is set, the GroWeather will calculate and display the correct barometric
pressure until the unit is moved to a different altitude or power is interrupted.
1. Determine the current barometric pressure.
Many TV and radio weather reports carry this information. Or you may call
your local airport control tower.
2. Press BAR to display current barometric pressure.
3. Press and hold down ENTER until the barometric pressure reading stops flashing.
At first, the entire barometric pressure reading will flash as a warning. After
four seconds the GroWeather will revert to normal entry mode (i.e., only one
digit flashing).
4. Use ENTER to set the correct barometric pressure.
See “Using the Enter Key” on page 17 for instructions on using ENTER.
5. When finished setting the barometric pressure, press any function key to exit.
The GroWeather saves the barometric pressure reading.
Displaying Stored Barometric Pressure
The GroWeather allows you to store a barometric pressure value at any time for
use in determining the change in barometric pressure. The pressure value is
stored along with the time and date at which it was stored.
1. Press BAR as necessary to display current barometric pressure.
2. To view the stored barometric pressure, press RECALL.
The stored barometric pressure appears on the right of the display.
STORED BAROMETRIC PRESSURE
3. To view the time at which the barometric pressure was stored, wait four seconds with-
out pressing a key.
The the time at which the barometric pressure was stored will automatically
appear on the right of the display.
