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-day information 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)—the official world time.

RADIO-CONTROLLED TIME* A radio-controlled time device is often confused with an atomic clock. However, a radio-controlled time device receives its time information from the atomic clock each day through an internal antenna. The radio- controlled 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 a radio-controlled time 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—this measurement 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

1 General

Important Note:

The Touch Screen Weather Station WS-3512 includes a Base Station (Receiver), a Transmitter unit, one Wind Sensor, Connecting Cables, an AC/DC Adapter, and a PC Software Package on CD-ROM.

The Base Station is equipped with a Touch Screen LCD Monitor and allows the display of a large variety of time and weather data.

From top to bottom:

• Radio-Controlled Time (Time)

• Calendar (Date)

• Weather Forecast (Tendency)

• Air Pressure and Air Pressure History (Pressure, Pressure

History)

• Wind measurement Also, the information text display (located at the bottom of the LCD), will show a variety of additional data.

Note: On the information text display, the min/max of today’s air pressure, max wind speed, wind gust will be shown time by time. If the set-up menu is selected, the information in the text display will be temporarily replaced by the menu operating features.

An added feature of the Weather Station is the readout of all measured and displayed time and weather data on a PC as well

Before inserting batteries, please carefully read the operation manual.

as the ability to upload the data to Internet Web Sites.

2 Important Operating Notes

• All actions and functions of the Weather Station are started on the Touch Screen by slightly touching (not pressing!) the switching areas appearing with star (٭) symbols (only in the text section at the bottom of the LCD) or the displayed values.

• The setting of functions, values, and units is performed by use of the switching areas ٭ON٭ or ٭OFF٭, ٭UP٭ or ٭DOWN٭ or by direct unit selection.

• Advancing to any next menu step with ٭NEXT٭, leaving or terminating all modes with ٭EXIT٭.

• Every time a programming step is activated by touching a switching area on the Touch Screen a tone will sound (with buzzer switched ON).

• If no areas are pressed for 30 seconds, the LCD will automatically revert to the normal display mode (automatic time out).

3 Getting 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 and set-up of the system. This allows you to make sure all

ter

Transmitter unit

components work properly before positioning them in their final

OUTDOOR TX

locations.

3.1 Wiring the System

AC/ DC adap

PC COM Port cable

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.

Wireless

Transmission

Direct cable

connection

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.

3.2 Power Supply

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

3.2.1 Batteries:

•

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.

3.2.2 The 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.

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.

3.2.3 Cable 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.

System operation with cable connection while at the same time

Note:

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.
