rain total.

monthly and yearly ET totals.

yearly ET total.

To clear a single weather variable:
1. Select the weather variable.
See “Selecting Weather Variables” on page 21.
2. Press and release 2ND, then press and hold CLEAR.
The variable you’ve chosen blinks. Keep holding the key until the value

Highs and Lows Mode
The Vantage Pro2 records highs and lows for many weather conditions
over three different periods: days, months, and years. Except for Yearly
Rainfall, all high and low registers are cleared automatically at the end of
each period.
For example, daily highs are cleared at midnight, monthly highs are
cleared at month–end midnight, yearly highs are cleared at year–end mid-
night. You may enter the month that you would like the Yearly Rainfall
accumulation to clear. The Yearly Rainfall clears on the first day of the
month you chosen. The Yearly High Rain rate clears using the same set-
ting. The following table lists the high and low modes for all the weather
variables:
