SECTION 1: INTRODUCTION
A. THE CAPRICORN II PLUS SYSTEM
The Capricorn II Plus weather station provides at-a-glance display of temperature,
wind chill temperature, relative humidity, barometric pressure, wind speed and wind
direction. Temperature may be displayed in Fahrenheit or Celsius. Barometric
pressure may be displayed in inches of mercury (in. Hg) or in millibars, at 0.01 in.
Hg (1 millibar) resolution. Wind speed may be displayed in miles per hour (mph),
kilometers per hour (km/h) or knots. Wind direction is displayed on a 16 point com-
pass.
User calibration is required for only wind direction and barometric pressure at the
time of installation. No other calibrations are required. The temperature sensor and
humidity sensor have been factory calibrated.
A memory feature keeps track of the highest and lowest temperatures and baromet-
ric pressures, and the highest wind speeds. A battery backup feature assures that
these readings will not be forgotten if power is either interrupted or cut off entirely.
An alarm feature provides an audible and visible alert when temperatures reach
predetermined highs or lows, or when the wind speed reaches limits set by the user.
The alarm can be coupled with an external relay to control remote electrical devices
such as pumps, motors and fans.
For those who need to record or transmit their weather data, the Capricorn II
RS232C Interface/Data Formatter option provides an easy connection to printers,
terminals, computers and modems. This option may be added at any time, and can
be easily installed by the user.
For those who want greater flexibility in the management and manipulation of their
weather data, WeatherView 32
TM
software (for IBM and compatible personal com-
puters) provides user-selectable data in a variety of formats. The flow of weather
data can be customized to fit the needs of each user. It can be printed, stored or
integrated into other databases to provide local forecasts.
