e.If the symbols do not change, the weather has not changed (or the change has been slow and gradual).
f.The sensitivity of the change in foreacst icon is set by the user in section F of the Detailed Set Up Guide.
E.Weather Tendency Arrows
1. Along with the forecast icon there is a pressure tendency arrow.
2. There is one that points up (on the left side of the LCD) and one that points down (on the right side of the LCD).
3.These arrows reflect current changes in the air pressure.
4.An arrow pointing up indicates that the air pressure is increasing and the weather is expected to improve or remain good.
5.An arrow pointing down indicates that the air pressure is decreasing and the weather is expected to become worse or remain poor.
6.No arrow means the pressure is stable.
7.A storm can be expected if there is a drop of 4 hPa or more in less than 6 hours. The clouds with rain icon will be displayed and the tendency arrow that points down will be
F.Barometric Air Pressure Reading
1.The actual barometric air pressure is displayed directly under the weather forecast icon
2.The relative air pressure is calibrated by the user through the programming mode.
3.Please Follow the programming instructions in section F of the Detailed Set Up Guide to set this feature.
G.Air Pressure History Bar Chart
1.The bar graph shows in hPa (Hekto Pascal) the recorded air pressure over the past
2.The horizontal axis shows the hours at increments of
3.The vertical axis is set by hPa: the “0” on this axis represents the current hPa, and + or – 1,3,5, or 7 shows (in hPa) how high or low the past air pressure was as compared to the current one.
4.The “0” on the vertical axis indicates the current air pressure value.
