ii.Glossary of Common Terms

NIST*

The National Institute of Standards and Technology maintains the primary frequency standard for the United States. The NIST also coordinates the United States time and frequency standards with other world standards. The NIST provides time and frequency services for United States clientele.

WWVB*

The WWVB is an AM radio station in Ft. Collins, Colorado, managed by the NIST. The WWVB’s function is to broadcast time-of-dayinformation derived from the NIST atomic clock, located in Boulder, Colorado.

ATOMIC CLOCK*

An atomic clock is an extremely accurate time device measuring time by the movements of electrons in cesium atoms. The NIST atomic clock is one of the most precise clocks in the world, accurate to 10 billionths of one second. The NIST’s atomic clock contributes to the international group of clocks calculating the Coordinated Universal Time (UTC)—theofficial world time.

3

RADIO-CONTROLLEDTIME*

A radio-controlledtime device is often confused with an atomic clock. However, aradio-controlledtime device receives its time information from the atomic clock each day through an internal antenna. The radiocontrolled time device searches for an exact time signal every night when the signal from the WWVB is the strongest. The signal can be received up to 2,000 miles away through aradio-controlledtime device.

LCD

“LCD” is an acronym for ”Liquid Crystal Display”. This is a common type of display screen used in televisions, computers, watches, and digital clocks.

BAROMETER & BAROMETRIC PRESSURE

A barometer is a device that measures the pressure of the air pushing on it—thismeasurement is called the barometric pressure. We don’t actually feel the barometric pressure because the air pressure is pushing equally in every direction.

RELATIVE AIR PRESSURE

Relative air pressure is the same as the barometric pressure. The calculation of relative air pressure is a combination of the absolute air pressure and the altitude.

ABSOLUTE AIR PRESSURE

Absolute air pressure is the actual air pressure on the barometer without regard to altitude.

INCHES OF MERCURY (inHg)

Inches of Mercury is the common unit of measurement for air pressure in the United States.

HECTOPASCALS (hPa)

Hectopascals are the common units of measurement for air pressure in the International System (SI) of measurement. The hectopascal holds the same value

3Getting Started

First you must decide whether to use batteries or the AC/DC adapter to operate the system. Both methods allow the connection of Transmitter unit and Base Station by cable or by 433 MHz radio signal.

Note: When setting up the Weather Station it is important to tentatively perform in close proximity (e.g. on a table) a complete wiring andset-upof the system. This allows you to make sure all

7

components work properly before positioning them in their final locations.

3.1Wiring the System

AC/ DC adapter

Transmitter unit PC COM Port cable

TX

OUTDOOR

Wireless

Transmission

Direct cable connection

Independent of the final operating mode at first, the fixed cable of the Wind Sensor has to be connected to the Transmitter unit by plugging it into the marked receptacle.

8

The direct cable connection of Transmitter unit and Base Station can be used if:

the flexibility of 433 MHz radio transmission is not needed and

data transmission absolutely free of any environmental interferences is wanted.

3.2Power Supply

The Weather Station can be powered by the use of batteries, by the AC/DC adapter or, by direct cable connection.

3.2.1Batteries:

First insert (2) "C" batteries into the battery compartment of the Transmitter unit.

Immediately following this insert (3) AA 1.5V batteries into the battery compartment of the Touch Screen Weather Station.

Please help in the preservation of the environment and return used batteries to an authorized depot.

3.2.2The AC/DC Adapter:

First insert (2) "C" batteries into the battery compartment of the Transmitter unit.

Immediately following this, connect the AC/DC adapter to the Base Station and then plug it into a regular outlet.

9

OUTDOOR

TX

Note: In both cases it is important to power the units in this order because the transmitter will send an identification code which has to be received and stored by the Base Station within the first few minutes of operation.

After doing this, full operation of the entire Weather Station System is ensured.

3.2.3Cable Connection:

An additional feature of the direct cable connection (mentioned in Item 3.1 above) is when using the AC/DC adapter, power is provided to both the Base Station and the Transmitter unit by only the AC/DC adapter.

Note: System operation with cable connection while at the same time providing power to the Base Station solely by batteries is not recommended due to the considerably higher power consumption. The batteries may however remain in the unit for emergency supply in case of a power failure.

A change from cable operation to 433 MHz radio transmission or vice versa is possible because the Weather Station will recognize this change and will automatically switch to the appropriate operating mode.

10

3.3System Start

After inserting the batteries and connecting the AC/DC adapter, the LCD of the Weather Station will, for a few seconds, display all possible display segments for checking.

Immediately after this, the unit will enter the “play mode”, during which for about 15 minutes all measured and received weather data are being switched through, updated, and displayed. During this time period there will be no reception of the WWVB time information.

Note: The play mode phase allows the user of the Weather Station to check all cables for correct connection and all components for correct function. The latter will be possible by manually turning thewind-gauge,moving theweather-vane,etc.

After completing the play mode, the Touch Screen Weather Station will automatically switch to the normal display mode from which all further settings can be performed by the user. At this point of time, the unit will also automatically start reception of the WWVB time information.

Important Note:

Reception of the radio-controlledtime information will only take place after completion of the play mode (approx. 15 minutes). If the user wants to start the system without waiting for completion of the play mode it can be terminated prematurely by touching the TIME display once in the upper left corner of the LCD.

Prior to manual setting or reception of radio-controlledtime information there will be no recording of weather history data.

3.4Positioning

Once you have verified that all of the components of the weather station are working, they can be positioned in their permanent places. Before permanently mounting, make sure that all components work properly together at their chosen mounting or standing locations. If e.g. there appear to be problems with the 433 MHz radio transmission they can mostly be overcome by moving the mounting locations.

11

Note: Commonly the radio communication between receiver and transmitter in the open field can reach a distance of up to 330 feet providing that there are no interfering obstacles such as buildings, trees, vehicles, high voltage lines, etc.

Radio interferences such as PC screens, radios or TV sets can, in bad cases, entirely cut off radio communication. Please take this into consideration when choosing standing or mounting locations.

4Setting Up

Note: Because of the default settings already determined by the manufacturer it may not be necessary for the majority of users to perform – except the Relative Air Pressure (see further down) - any further basic settings. Changes, however, can be easily made.

For basic settings, the following menu is started by touching the Touch Screen in the center of the text display (last 2 lines on the LCD). Touching the display ٭SETUP٭ will enter the setup mode.

The basic settings can now be performed in the following successive order:

LCD Contrast → Contrast can be set in 8 steps from 0 to 7 (Default 4).

12

Time Zone → Time Zones can be set in the range from-12to +12 hours (Default EST).

WWVB Radio-Controlled Clock (RCC) → ON/OFF. In setting “OFF“ the clock is operating as a normal Quartz clock (Default RCC OFF).

12/24 hour Time Display Format (Default 12h Format).

Units

Wind Speed Display (Wind) in km/h, mph, m/s, knots or Beaufort (Default mph).

Air Pressure (Press) in hPa or inHg (Default inHg).

Relative Air Pressure (Rel. Pressure) → To be set to the locally valid reference air pressure with regard to the local height above sea level (Default 29.98 inHg).

13

Weather Tendency (Tendency) → Setting to a definite switching threshold (2 hPa to 4 hPa) for a change in display of weather icons (Default 3 hPa).

Storm Warning (Storm) → Setting to a definite switching threshold for storm warning display at a decrease of air pressure from 3 hPa to 9 hPa over 6 hours (Default 5 hPa).

Activate/Deactivate storm warning alarm with ٭ON٭ / ٭OFF٭ resp. (Default OFF).

Relearn Mode (Relearn Tx) → Allows recognition of the outdoor transmitter (e.g. after a battery change in the transmitter) without the necessity of a comprehensivere-setupof all system components → Acknowledge with ٭CONFIRM٭.

14

Default Settings (Factory Reset) → Allows clearing of all weather data innon-volatilebuffer memory (EEPROM) and to reset of all set and/or stored values to the factory settings set prior to shipment → Acknowledge with ٭CONFIRM٭.

Note:

It will take 5 minutes for the factory reset process. During this period, the text “Factory Reset In Progress” will be shown. After the reset process is finished, the LCD will switch off and the text “Remove Battery” will be displayed. Remove the battery and perform system start again. See “3 - Putting in Operation” paragraph.

To leave the basic settings procedure (Setup Mode) touch ٭EXIT٭.

5Display of Stored MIN/MAX Alarm Value Settings

Named values are in each case upon recall being simultaneously displayed and flashing in their respective display sections.

To recall measuring and alarm values, the menu shown below will have to be activated by touching the Touch Screen in the center of the text display section (last 2 lines at the bottom of the LCD). The display of the values is started by touching the displays ٭MINMAX٭ or ٭ALARMS٭.

15

With ٭MINMAX٭ the below shown menu step is activated, which in return leads to the displays of the stored Min/Max values by use of ٭MIN٭ / ٭MAX٭, which on their part again can be directly selected.

Note: During individual displays of the stored Min/Max values the top line of the LCD screen will automatically display the time and date of their storage.

The following menu item will appear upon touching the display labelled ٭ALARMS٭.

Because of the constant access to the respective opposite menu item ٭MINMAX٭/٭ALARMS٭, it is possible at any time to toggle between the MIN/MAX and ALARMS value displays.

Any action can immediately be terminated through ٭EXIT٭.

6Radio-ControlledWWVB Clock

The Radio-ControlledWWVB Clock is normally controlled by the radio signal of the WWVB time code transmitter and will thus set time and date automatically. Under bad reception conditions however both can be set manually as follows:

Setting the Time

The action is started by touching the time display in the TIME section of the Touch Screen.

16

Start ٭TIME٭ in the menu section (last 2 lines on the LCD).

Set the hours and minutes. Leave the mode with ٭EXIT٭ or wait for automatic time-out.

Setting the Date

The action is started by touching the date display in the DATE section of the Touch Screen.

Set the year, month and date of day. Leave the mode with ٭EXIT٭.

17

Note: By touching the DATE section twice, the display will toggle between the following:

Date in MM.DD.YY format (12 hour time format) or Date in DD.MM.YY format (24 hour time format)

Weekday, Month, Date of Day (12 hour time format) or Weekday (in English abbreviation), Date of Day, Month (24 hour format)

Seconds

Set Wake-upAlarm Time

Setting of Wake-upAlarm

The action is started by touching the time display in the TIME section. Start ٭ALARM٭ in the menu section (last two lines on the LCD).

Set hours and minutes of the wake-uptime. Leave the mode with ٭EXIT٭.

Note: Thewake-upalarm is activated/deactivated by twice touching the TIME section. Here the alarm symbol (((•))) will show or disappear after ٭EXIT٭ (or automatictime-out).

7Weather Tendency

Call up the tendency display by touching the weather symbol in the TENDENCY section.

18

The text section (last 2 lines on the LCD) will show because (with time and date) the weather condition corresponds to the presently displayed weather symbol Sunny, Fair (Cloudy with sunny intervals) or Rainy.

Note:

Up and down arrow indicate weather tendency

Advanced storm warning is displayed by Rainy symbol with a flashing down arrow

Every minute, when a new pressure reading is obtained, this value is compared to pressure readings from last 2 hours and the biggest resulting difference is displayed in the difference barometer.

8Air Pressure History

The air pressure history shows the progress of the air pressure over a time period of 24 or 72 hours in form of a 7-stepbar graph, where the length of the utmost right bar represents the present air pressure and the remaining bars show the progress of the air pressure with regard to the present air pressure.

Note: The time resolution of the bar graph can be changed from fine (0 to-24h) to coarse (0 to-72h) and back by touching the PRESSURE HISTORY section once.

19

9Features and Operations

Air Pressure (Pressure), Relative and Absolute

Wind Speed, Wind Gust

Important Note!

Because the operating procedures in all measurements are identical, the various functions of the weather station will be explained once here by the following example of “Air Pressure”.
