Capricorn II Plus User Manual
The Capricorn II Plus also records (but does not display) the average wind speed.
The average wind speed is determined by averaging wind gusts over a four-second
period. Average wind speed has three purposes. It is used to calculate the wind chill
factor. It is also used to trigger the wind speed alarm. Finally, the highest average
wind speed is also kept in memory and displayed during operation of the Memory
function.
The flashing LED light located in the bottom right-hand corner of the Wind Speed
display indicates that the microcomputer is active. A steady light indicates an “inac-
tive” condition. If this occurs, unplug the power cord, wait 15 seconds and reconnect
the power cord.
Units of Measure – Move the MPH/Knots/KPH switch on the front panel of the
console to display wind speed in either miles per hour, knots or kilometers per hour,
respectively.
1 knot =
1.15078 mph
1 km/h =
0.62137 mph
E. WIND DIRECTION
Wind direction is displayed in a rosette of 16 LED compass points, 22.5
o
apart. If the
wind direction sensor is installed as described in Section 3: Installation, the sensor
should be accurate to /- 11.25
o
(or better). The illuminated compass point
indicates the direction the wind is coming from. For example, when the unlabeled
light between “N” and “NE” is illuminated, the wind is blowing from (or “out of”) the
“NNE.”
The Wind Direction display will always record the direction of the wind vane, even
when there is no detectable wind. As a result, when the wind speed display reads
“0”, the compass point indicating the direction of the last detectable wind activity will
remain illuminated.
E. ALARM FEATURE
The alarm feature allows the user to be warned of temperature and/or wind speed
alarm conditions by providing visual, audible, and output contact closure response.
Once set, the Capricorn II Plus simultaneously evaluates both wind speed and
outdoor temperature for alarm conditions.
Activating the Alarm
The purpose of the alarm feature is to draw the user’s attention to the alarm condi-
tion. The purposes of the LEDs in the “Alarm” box on the front panel are 1) to pro-
vide a visual indication of an alarm condition and 2) to indicate whether the alarm
condition relates to temperature or wind speed. A speaker mounted inside the back
panel provides an audible indication of an alarm condition, if desired.
To activate the alarm, move the Alarm switch on the front panel of the console from
the “Off” position to either the “Silent” or ”Audible” position.
