4. Hectopascal pressure sensitivity can be set to suit the user s requirement for weather forecasting from 2 hPa to 4 hPa see Basic programming below For areas that experience frequent changes in air pressure which does not necessarily reflect a change in the weather requires a higher hPa setting compared to an area where the air pressure is stagnant For example if 3 hPa is selected then there must be a fall or rise in air pressure of at least 3 hPa before the weather station will register this as a change in weather Air Pressure LCD Section 1 The air pressure reading is displayed here Press the PRESSURE key to toggle between relative and absolute air pressure displays Notes to Absolute and Relative Air Pressure Absolute air pressure provides the display of the true measured air pressure of the current time and location This is not programmable and the absolute air pressure range of the weather station is from 760 hPa to 1099 hPa standard air pressure at an altitude of 2 300 metres is around 760 hPa Relative air pressure is the one value that is calculated back to sea level from the local absolute air pressure and can thus be taken as a reference for weather condition and weather development for the entire country It can be programmed to represent your local surroundings Since the relative air pressure is also the one value given by various newspapers TV and radio broadcasting stations in their daily weather forecasts for the

It is important to keep all the connected extension heads away from rain moisture and other extreme weather conditions as exposure can cause short circuits and damage to this item 13 Base Station With two foldable legs at the back of the unit the base station can be placed onto any flat surface or wall mounted at the desired location by the hanging holes also at the back of the unit It is important to check that the 433MHz if using wireless connection can be received before permanently mounting any of the units Should the base station not display the 433MHz weather data from the sensors then relocate the units Once the signals are received the system can be affixed Also if you have selected to use cable connection ensure that distances can reach all desired locations before affixing any unit permanently Mounting the Wind Sensor onto a mast Vertical mast p A 9 N Fixed with Nylon 3 strap Wind fan First check that the wind fan and the wind vane can rotate freely before fixing the unit For correct and accurate readings it is important to mount the sensor so that the front marked E is pointing in East West direction The wind cups must be below the mounting bracket The wind sensor should now be mounted using the screws provided onto a mast to allow the wind to travel around the sensor unhindered from all directions ideal mast size should be from 16mm 33mm Place the Wind
