LCD Display operating instructions
The LCD Display can be operated via the four end panel buttons and the three-rear panel "dip" switches.
The LCD display has three main modes of operation which are: Clock, Temperature, and Rainfall (supplied
separately)
Clock
The clock forms part of the displays "scroll" cycle and is displayed in 24hr time format.
Setting the Clock
In order to set the clock, firstly ensure that the clock is visible on screen then press the "A" button. The hour
element will then start to flash. Pressing "B" will then cause the display to advance by one. Keep pressing "B"
until the desired reading is acquired. A press of "A" will the advance the flashing element to the next
parameter to be adjusted; again use "B" to advance the reading. Once all time / date parameters have been
set, leave the display until the flashing element stops. The clock is now set, and normal operation can resume.
Outside Temperature
The LCD temperature display shows the outside temperature at the roof top sensor.
Celsius or Fahrenheit display may be selected by pressing the C/F button on the right side of the cabinet.
Pressing button "A" on the end of the display will display the Min/Max readings taken by the display.
Holding button "B" while the min / max readings are displayed for 5 seconds will then reset the two readings.
Pressing "A" again will take you back to the real time temperature reading.
Barometric Pressure
Calibration of the barometer is achieved by adjustment of the screw head on the barometer movement,
accessible through a hole in the back panel.
The barometer also uses a second needle which can be used to shadow the main needle. This needle is
attached to the gold knob on the glass of the unit. Rotate the gold know so that the shadow needle is directly
above the main barometer needle. Now as the air pressure changes and the main needle moves with the
mechanism, the amount of air pressure swing can be noted daily.
Wind Speed and Direction
As long as the wind sensor has been mounted correctly and pointing North as described, these two readings
do not require and setting and just need to be monitored.
The wind direction is monitored via the eight LED indicators and the wind speed via the mechanical movement
driving the black needle.
Gust Pointer
The display incorporates a "Gust" pointer which can be used to indicate the highest "Gust" of wind the station
has been subjected to.
Rotate the gold knob anti-clockwise until the gust pointer needle makes contact with the wind speed pointer.
It will now be carried up to show the maximum speed and remain there until reset manually using the gold
knob once more.
Rainfall (optional Extra)
If a Rainfall Sensor is to be used, the display has to be enabled by turning on "Dip" switch 2 on the rear of the
display.
Once the Rain Sensor is connected, the display will now show the following rainfall readings:
•
Current rainfall amount
•
Accumulated rainfall amount
The rainfall display shows the amount of rainfall since last reset in mm or inches selectable via "Dip" switch 3
on the rear of the display.
