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, first determine the percentage of error, then:
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 
3. Press and release 2ND and then 
press and release SET to display 
the RAIN ERROR IN PERCENT 
screen.
 
4. Enter the error. Enter a negative number if your station is under reporting; enter a positive 
number if it is over reporting. For example, if your station is low by 2%, enter  -2. If your 
station is high by 4%, enter 4. Press the + and - keys to add or subtract from the percent 
amount. 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.
Note: This calibration will not retroactively affect past rain totals. It will only affect future rain data.
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.
