Selecting Units of Measure

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.

Press 2ND and UV to display the current UV index. The current UV

 

RAINYR

 

 

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.

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).
