Pressure Trend
The pressure trend arrow indicates the current barometric trend, measured over
the last three hours. The pressure trend is updated every 15 minutes. The pres-
sure trend requires three hours of data in order to be calculated so it won’t dis-
play right away on a new station. The pressure trend is indicated on the console screen,
as long as the required data is available.
UV (Ultraviolet Radiation)
Press 2ND and UV to display the current UV index. The current UV
index is the amount of ultraviolet radiation the sensor is currently
reading.
Press 2ND and UV again to display the accumulated UV index for the day. The accu-
mulated UV index is the total ultraviolet radiation that the sensor has read throughout
the day. The accumulated UV index for the day is reset to zero every night.
Note: Requires a UV sensor. See “Optional Sensors & Transmitting Stations” on page 2.
Heat Index
Press 2ND then press HEAT to display the Heat Index.
THSW Index
After you have selected the Heat Index, press 2ND then press HEAT again to select the
Temperature Humidity Sun Wind (THSW) Index. The THSW Index is only available
on stations equipped with a solar radiation sensor.
The Heat Index and the THSW Index display in the same place on the screen and are
displayed in degrees Fahrenheit (ºF) or Celsius (ºC).
