General Tools and Instruments WS831DL - Manual (Page 4)

CUSTOM WEATHER STATION SETTINGS
The basic operation of your weather station has been designed to work right out of the box, 10 minutes
after power is provided to the main unit. To use your station, you will have to complete the steps
identified under INITIAL SETUP while this section of the manual will provide you with additional
operational details and suggestions for custom settings and alarms including:
• The time alarms (Clock and Alarm Window).
• The temperature alerts (Temperature and Humidity Window).
• Daily rainfall alerts (Rain Window).
• Wind alerts (Wind Window).
PRESSURE AND WEATHER FORECAST WINDOW
Your weather station is designed to accurately display (local) barometric pressure, sea level pressure,
weather forecast and moon phases. Historical statistics can also be viewed, including the sea-level
pressure for the past 24 hours, moon phase for the past and following 39 days, and a selectable
barchart for viewing pressure/ temperature & humidity history. Pressure is displayed inHG (English),
hPa/mBar (scientific) or mmHg (metric). Altitude is displayed in meters or feet.
NOTE: An altitude display of 99o, is actually 990 feet, etc. Pressure can be displayed as: “inHG” (default)
inches of mercury, “mmHG” is millimeters of Mercury and “hPa/mBar” is scientific hectoPascal.
SELECT PRESSURE AND WEATHER FORECAST WINDOW
Press main unit UP▲ or DOWN▼ until the weather forecast icon begins to flash, upper display left
corner.
NOTE: Wait at least 5 - 10 minutes after initial set up to view a pressure or altitude information.
PRESSURE AND ALTITUDE INFORMATION
Briefly press SET button to alternate between the sea level pressure, local pressure and local altitude
settings.
The unit should be set to the default settings of: inHG (Inches of Mercury), and 33 FEET. These
parameters can be changed as desired at a later date, using the steps outlined in the section for
Setting or Changing Pressure and Altitude settings.
CHANGING PRESSURE AND ALTITUDE PARAMETERS
The weather station is designed to measure local pressure and calculate the other two parameters
based on the Local Pressure. Sea Level Pressure and Altitude are interdependent. If you enter altitude, it
will calculate sea level pressure, if you enter sea level pressure, it will automatically calculate altitude.
During initial power up (within the first 5 – 10 minutes) the weather station will not operate.
These parameters can be modified after the display has stabilized.
Select the Pressure and Weather Forecast window. From the main unit: Press UP▲ or DOWN▼ until
the pressure and weather forecast icon
starts flashing.
CHANGING OR SETTING SEA LEVEL PRESSURE
• Press SET until the local pressure with the word “SEA LEVEL” is displayed.
• Press and hold MEMORY until the pressure unit is flashing, inHG, mmHG or hPa/mBar.
• Set the sea level pressure units by pressing the UP▲ or DOWN▼ buttons to adjust the pressure
value.
• Press MEMORY to confirm your selection.
CHANGING OR SETTING ALTITUDE
• Press SET button until the local altitude value will be displayed.
• Press and hold MEMORY until the altitude unit is flashing, FEET or METERS.
• Press and hold SET until the pressure reading is flashing.
• Set the altitude unit in meters or feet by pressing the UP▲ or DOWN▼.
• Press SET to confirm your selection.
NOTE: Locate your altitude with a portable GPS receiver or topographical map. Locate barometric
pressure at: http://weather.noaa.gov/ or, alternatively, from local radio or TV weather channels.
VIEWING THE SEA LEVEL PRESSURE HISTORY
• From any mode, press the HISTORY button. Unit will select the Pressure/ Weather display.
• When the SEA LEVEL is displayed, press HISTORY repeatedly viewing the sea level pressure
history for the past 24 hours in hour increments.
• If no buttons are pressed for 5 seconds, the unit will automatically exit HISTORY and return to the
Pressure and Weather Forecast Window.
VIEWING THE PRESSURE, TEMPERATURE AND HUMIDITY BAR CHARTS
The pressure bar graph shows barometric pressure variations over the past 24 hours. This is very
useful for understanding the Barometric trends that are used in weather forecasting. Each bar icon
represents 0.06 inHg.
Alternatively, the bar chart can be used to display 24 hour trend data for Sea Level Pressure, CH 1
Remote temperature or Ch1 Remote humidity.
Select the Pressure and Weather Forecast window, press and hold ALARM/CHART button to toggle the
bar chart title at the right bottom corner of the chart. Alternate between “PRESSURE” “CH1”
temperature (thermometer icon) and “CH1” relative humidity.
VIEWING THE MOON PHASE HISTORY
The unit indicates the current moon phase and using the MEMORY control, will permit viewing of past
of future days. Previous moon phases are selected with the minus sign selected: -1 day, -2 days, etc. or
future moon phase are selected based on the days ahead: +1 day, + 2 days, etc up to 39 days.
• After selecting the Pressure and Weather Forecast, press MEMORY, so “+ 0 days” is flashing.
• Press UP▲ or DOWN▼ selecting from today’s date a future (+) or past (-) days and the
corresponding moon phase will be displayed. Press and hold either button for a quick advance.
• To exit, press MEMORY button.

NOTE: The weather forecast accuracy is approximately 70%. Display shows 12 to 24 hour forecast, not

night-time.
TEMPERATURE AND HUMIDITY WINDOW
The weather station supports Indoor temperature & humidity & up to three remote temperature and
humidity sensors (only 2 remotes are provided).
Temperature can be displayed in either Celsius (ºC) or Fahrenheit (ºF). The main unit calculates indoor
comfort level - Wet, Comfort or Dry or Dew Point based on temperature & humidity readings.
A temperature alert level is available for each channel. The main unit can be programmed to alarm if
the temperature exceeds or falls below the pre-set upper and lower limits. Thermo-Hygrometer remote
battery status is monitored on the main unit.

SELECTING TEMPERATURE AND HUMIDITY WINDOW
Press main unit UP▲ or DOWN▼ until the IN icon on the upper right will flash.
VIEWING TEMPERATURE AND HUMIDITY FOR EACH CHANNEL
At any time simply press the CHANNEL button to recall a different remote thermo hygrometer channel.
CHANNEL AUTO-SCAN DISPLAY:
To enable automatic scan of the different channels, press and hold CHANNEL, until the icon is
displayed. Channels will be alternately displayed with a 5-second delay.
NOTE: The temperature alerts have a 0.5 ºC deviation to prevent false alarms due to small temperature
fluctuations. Temperature has to fall below (or above) the programmed level(s) to activate the
alert.
