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.
Indicating the barometric Indicating the barometric
pressure trend is rising pressure trend is steady
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
conirm.
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 falling

8. Thermometer

8.1 RF Transmission Procedure:

• The main unit automatically starts receiving transmission from outdoor thermo sensor
for outdoor temperature after batteries are inserted.
• The thermo sensor unit will automatically transmit temperature to the main unit after
batteries inserted. For having more than one external transmitter (Maximum3), select
the Channel, CH1, CH2 or CH3 to ensure each sensor is transmitting difference
channel before inserting batteries. The channel select switch (D3) is at the back of the
thermo sensor.
• If main unit failed to receive transmission from outdoor thermo sensor in irst 3 minutes
after the batteries inserted ("- - . –"display on the LCD), hold "Channel" button (B10) for
3 seconds to receive transmission manually. RF icon "
Note: "WEATHER/HISTROY" (B6), "HPA/INHG/MMHG/▲ (C/F)" (B7), "RELATIVE/
ABSOLUTE"(B8), "MAX/MIN/▼" (B9) buttons will not function while scanning for thermo
sensor's signal unless they are well received or stopped manually.
8.2 Temperature & Humidity
(1) Outdoor Temperature--- Channel Selection
• Press "CHANNEL" button (B10) to view the 3 Channels' temperature & humidity. The
