last noticeable change in the weather was when it was sunny (the sun icon only). Therefore, the next change in the weather will be cloud with rain icons since the indicator is pointing downwards.

Note: Once the weather tendency indicator has registered a change in air pressure, either the upward or downward tendency arrow will be displayed until the tendency changes again.

AIR PRESSURE HISTORY GRAPH

The LCD shows the relative air pressure value and the air pressure history on a bar graph. Press the SET key to toggle between Mode1 and Mode2 of the display.

Mode 1: The bar graph displays the air pressure history of the past 24 hours in seven steps. The horizontal axis represents the last 24 hours of air pressure recording (‐24, ‐18, ‐12, ‐8, ‐6, ‐3 and 0 hour).

Mode 2: The bar graph displays the air pressure history of the past 72 hours in seven steps. The horizontal axis represents the last 72 hours of air pressure recording (‐72, ‐48, ‐36, ‐24, ‐12, ‐6 and 0 hour).

The vertical bars are plotted at each of the seven steps and give the trend over the recorded period. The 0 hour vertical bar will always display at the midline height to indicate the current air pressure. The varying height of bars in other columns on the graph indicate a relative change in air pressure up or down from the previous measurement.

New pressure measurements are compared to previously recorded pressure measurements. The pressure change is expressed by the difference between the current ("0h") and the past readings in divisions of ±0.06 inHg or ±2 hPa. If the bars are rising from left to right, this indicates that the weather is getting better due to an increase in air pressure. If the bars are falling from left to right, this indicates that the weather is expected to get worse due to a drop in air pressure.

At every full hour, the current air pressure is used as a basis for the display of a new graph bar. The existing graph is then moved one column to the left.

Note: For accurate barometric pressure trend, the Weather Center should operate at the same altitude. Should the unit be moved, for instance from the ground to the second floor of the house, the readings for the next 48‐60 hours shall be discarded.

Note: The bar graph will scroll right to left regularly to prevent LCD burnout.

WIND DIRECTION AND WIND SPEED MEASUREMENT

∙A pointer on the outer circle of the compass indicates the current wind direction.

∙The last 6 wind directions are displayed with pointers on the inner circle.

∙The wind direction (abbreviation or degrees) is displayed in center of compass.
