Configurable parame- ters are; sensor type, logging interval, Degree Day calculation method and latitude and altitude (model 2900ET only). -
Page 15: Setting The Sensor Type
Setting the Sensor Type Although the keypad can be used to assign a sensor to an exter- nal port, this should only be done when initially starting the sta- tion, re-starting a station whose memory has been cleared, or for adding a sensor to a previously unused port. -
Page 16: Setting Geographic Data For The Et Report
Setting Geographic Data for the ET Report In addition to temperature, relative humidity, wind speed and so- lar radiation data, the Penman-Monteith algorithm used by the 2900ET station uses the station latitude and altitude to compute reference ET. These are input as follows: 1. -
Page 17: Setting The Degree Day Calculation Method
Selecting the Degree Day Calculation Method The weather station has 2 options for calculating Degree Days (see Degree Days/Chill Hours, p. 31). The weather station must measure air temperature for this option to be available. The de- sired method is selected as follows: 1. -

Page 24: Resetting The Rain Counter
Resetting the Rain Counter The weather station maintains two rain counters (see LCD Screens, p. 28); rain since midnight and total accumulated rain- fall. The second counter can be reset to zero at any time. For ex- ample, to track weekly rainfall accumulations, the counter could be zeroed every Monday morning. -
Page 25: Daily Archive
Daily Archive The weather station features an archive that allows you to look at historical data for that location without downloading the data. The archive is regularly updated whenever the data logger is actively collecting data. The daily archive retains the last 30 days of data. If the battery power runs low, the station’s firmware will stop measuring and archiving data until the battery is replaced. -
Page 26: Battery Replacement
Battery Replacement The 2000 Series weather stations are powered by 4 AA batteries. This will provide enough power for 1 year of continuous use with lithium batteries, or 10 months with alkaline. The battery com- partment is accessed by removing the thumbscrews on the upper cover of the WatchDog (above the LCD). -
Page 27: Clearing The Loggers Memory
Clearing the Logger’s memory The memory of the 2000-Series weather station is not automati- cally cleared when the station is downloaded or the batteries are replaced.
