Calibrating, Setting, and Clearing Variables
28
Calibrating Barometric Pressure
Before calibrating the barometric pressure, be sure the station is set to the
correct elevation. See “Screen 10: Elevation” on page 11 for more information.
Find the nearest source of barometric pressure, such as a local airport, to get a
current barometric pressure.
1. Press BAR to select barometric pressure.
2. Press and release 2ND, then press and hold SET. The barometric pressure
variable blinks.
3. Continue holding SET until the Weather Center reads “SET BAR”.
4. Press the < and > keys to select digits in the variable.
5. Press + and - keys to add to or subtract from the digit’s value.
6. Press DONE to exit calibration.
Calibrating Rain
The Rain Error in Percent refers to the measuring error of your rain collector. To
set the rain error percentage:
1. Enter Setup Mode by pressing 2ND and then SETUP.
2. Press DONE multiple times until Screen 13: Rain Collector displays. (See
“Screen 13: Rain Collector” on page 12 for more information.)
3. Press and release 2ND
and then press and
release SET to display
the RAIN ERROR IN
PERCENT screen.
4. Press the + and - keys to add or subtract from the percent amount. A positive
percentage rate adds a certain percentage to all the rainfall totals. A negative
percentage rate subtracts a certain percentage from all rainfall totals. The
Rain Error Percentage range is -25 to 25 percent. (Not all corrections are
available, so you may have to choose the closest one.)
5. Press and hold DONE to save the setting and exit Setup Mode.
Setting Weather Variables
Setting a weather variable allows you to manually enter a total for that weather
variable that accrued prior to installation of your weather station.
You can set values for the following weather variables:
•
Daily Rain — Sets the daily rain total. Monthly and yearly rain totals are
updated.
• Monthly Rain — Sets the total rain for the current month. Does not affect
the yearly rain total.
• Yearly Rain — Sets the current year’s rain total.
• Daily ET (Evapotranspiration) — Sets the daily ET total. Monthly and
yearly ET totals are updated.
• Monthly ET — Sets the current month’s ET. Does not affect yearly total.
• Yearly ET — Sets the current year’s total ET.
