Clearing Weather Variables
The following weather variables can be cleared:
• Barometer—Clears any pressure offset used to calibrate the station, and
the elevation entry.
• Wind—Clears the wind direction calibration.
• Daily rain—Clearing the daily rain value is reflected in the daily rain total,
the last 15 minutes of rain, the last three hours of rain sent to the forecast
algorithm, the umbrella icon, and the monthly and yearly rain totals. Clear
the daily rain total if the station accidentally recorded rain when the ISS was
installed.
• Monthly rain—Clears the monthly rain total. Does not affect the yearly
rain total.
• Yearly rain—Clears the yearly rain total.
• Daily ET—Clears daily ET and subtracts the old daily ET total from the
monthly and yearly ET totals.
• Monthly ET—Clears the current monthly ET total. Does not affect the
yearly ET total.
• Yearly ET—Clears the current yearly ET total.
To clear a single weather variable:
1. Select the weather variable.
See "Selecting Weather Variables" on page 18.
2. Press and release 2ND, then press and hold CLEAR.
The variable you've chosen blinks. Keep holding the key until the value

Clearing the barometer value also clears the elevation setting.
