Ea2 BL508 Bl [10/13] Barometric pressure reading

• If there is any inconsistency of weather forecast between Local Weather Station

and this unit, the Local Weather Station's forecast should prevail. We will not hold

responsible for any trouble that may come up due to wrong forecasting from this unit

7. Barometric Pressure Reading

7.1 Barometric Trend Pointer (A6)

The trend pointer displayed on the LCD (A6) indicates the trend of the Barometric

pressure.

7.2 Absolute / Relative Air Pressure

• Press the “Absolute / Relative” button [B8] to toggle between Absolute or Relative

pressure display.

“ABS” is shown for Absolute Pressure; “REL” is shown for Relative pressure

• Absolute pressure is the actual pressure measured by the Main Unit

• When viewing Relative pressure, hold “Absolute / Relative” button [B8] for 3 seconds,

press “▲” (B7) or “▼ “(B9) button to adjust, press “Absolute / Relative” button [B8] to

conrm.

Note: Check your local weather station for Sea Level pressure information

7.3 Past Hour Air Pressure (History) Reading

• Press “HISTORY” button (B6) to view the past 12 hour’s Barometric Pressure history.

The hour is indicated on LCD (A9)

Press “HISTORY” button

• 0 HR = Current Barometric Pressure Reading

• -1HR = Barometric Pressure Reading in 1 hour ago

• -2HR = Barometric Pressure Reading in 2 hour ago……..etc

• Hold “hPa/inHg/mmHG” button [B7] for 3 seconds to select the unit for barometric

pressure meter in hPa, inHg or mmHG.

7.4 Barometric Pressure Bar Graph

The Barometric Pressure Reading at 0hr, –2hr,-4hr,-8hr,-12hr is recorded and shown on

Barometric Pressure Bar Graph [A8]. The Graph is displayed in both hPa and inHg

Indicating the barometric

pressure trend is rising

Indicating the barometric

pressure trend is steady

Indicating the barometric

pressure trend is falling

5. Installation

5.1 Main Unit

The main unit can be placed onto any at surface (C3), or wall mounted by the hanging

hole (C1) at the back of the unit.

5.2 Outdoor Thermo sensor

The remote sensor should be securely mounted onto a horizontal surface.

Note:Transmissions between receiver and transmitter can reach up to 30m in open area.

Open Area: there are no interfering obstacles such as buildings, trees, vehicles, high

voltage lines, etc.

6. Weather Forecast Function

6.1 Operation

• After Batteries inserted, or holding “WEATHER” button (B6) for 3 seconds, weather

icon ash (A7) on the LCD. Enter the current weather pressing “▲” (B7) or “▼ “(B9)

button. Press “WEATHER” (B6) button to conrm the setting. The weather forecast

may not be accurate if the current weather entered is not correct.

• The current weather status should be entered again if the altitude of the Main Unit

is changed. (Barometric pressure is lower at higher altitude location. Therefore, altitude

change will affect the weather forecast). The weather station will start the rst forecast

at 6 hours later after the current weather status is entered.

6.2 Weather Conditions

There are totally 5 different weather status animations in the weather forecast.

Note:

• “ “ is shown if the weather forecast is Rainy and outdoor

temperature (any channel) under 0°C.
