Display Console Batteries Installation Remove the battery door on the back of the display, as shown in Figure 8. Install three AAA (alkaline or lithium)) batteries. The display will beep once and layout of display will light up for a few seconds to verify all segments are operating properly. Figure 8 4 Replace the battery door, and unfold out the desk stand to place the console in the upright position. Note: The battery is a back-up of weather station console, saving console settings when powered off from adaptor 3.4.3 Connect Sensor with Display Console Once the display console is powered up, it will automatically scan all the nearby Integrated Outdoor sensors. Note: Do not press any button until all the remote sensors report in the display screen, otherwise the display console will terminate to connect with remote sensors. Note: While in the search mode, the remote search icon will be constantly displayed until all the measured values received. The console will automatically switch to the normal mode from which all further settings can be performed. When connected with the Integrated Outdoor Sensor, the measured value (Indoor temperature,humidity,pressure,moon phase,time,wind speed,wind gust,wind direction,rain,outdoor temperature and humidity) will show up on the display console. Note: Make sure that the distance between weather station sensors and display console should be within 10ft (3m) to 100ft

(30m). If the weather station sensors is too close or too far away, it may not receive a proper signal. 3.5 Sensor Operation Verification 5 The following steps verify proper operation of the sensors prior to install the sensor array. 1. Verify proper operation of the rain gauge. Tip the Integrated outdoor sensor back and forth several times. You will heard a ticking sound within the rain gauge. Verify the rain reading on the display console is not reading 0.00. Each ticking represents 0.1 inch of rainfall. 2. Verify proper operating of the wind speed. Rotate the wind cups manually or with a constant speed fan. Verify the wind speed is not reading 0.0. 3. Verify proper operation of in/outdoor temperature. Verify the indoor and outdoor temperature match closely with the console and sensor array in the same location (about 5 to 10 (1.5 to 3 meters) apart).The sensors should be within 4F

/2C (the accuracy is 2F/1C). Allow about 30 minutes for both sensors to stabilize. 4. Verify proper operation of in/outdoor humidity. Verify the indoor and outdoor humidity match closely with the console and sensor array in the same location (about 5 to 10 (1.5 to 3 meters) apart).The sensors should be within 10% (the accuracy is 5%). Allow about 30 minutes for both sensors to stabilize. 7. Display Console Operation 7.1 Quick Display Mode Note: The display console has five keys for easy operation:

For example, if you set the high alarm to 80.0F(26.7C) and silence the alarm, the alarm icon will continue to flash until the temperature falls below 80.0F

(26.7C), at which point, the alarm will reset and must increase above 80.0F(26.7C) to activate again. Note: To prevent repetitive alarming of humidity, there is a 4% tolerance band in humidity alarm. For example, if you set the high alarm to 60% and silence the alarm, the alarm icon will continue to flash until the humidity falls below 56%, at which point, the alarm will reset and must increase above 60% to activate again. 8.4 Alarm and Key Beeper ON/OFF Press any button to silence the alarm sound. 15 In normal mode, press and hold the ALARM key for three seconds to toggle the BZ ON (beeper on) or BZ OFF (beeper off) depending on the current setting. Display console return to normal mode without any operation in three seconds. 9. Optional Calibration Mode Note: The calibrated value can only be adjusted on the display console.The outdoor remote sensor(s) always displays the un-calibrated or measured value. Note: The measured humidity range is between 10% and 99%. Humidity cannot be accurately measured outside of this range. Thus, the humidity cannot be calibrated below 10% or above 99%. The purpose of calibration is to fine tune or correct for any sensor error associated with the devices margin of error. The measurement can be adjusted from the console to calibrate to a known source. Calibration is only useful if you have a known calibrated source you can compare it against, and is optional. This section discusses practices, procedures and sources for sensor calibration to reduce manufacturing and degradation errors. Do not compare your readings obtained from sources such as the 16 internet, radio, television or newspapers. They are in a different location and typically update once per hour. The purpose of your weather station is to measure conditions of your surroundings, which vary significantly from location to location. The profession weather station supports up to eight remote thermo-hygrometer sensors. Each of the eight sensors can be calibrated. 9.1 Calibration of Temperature Mode In normal mode, press and hold the SET and CHANNEL/+

keys at the same time for five seconds to enter the temp calibration mode. The indoor temperature will begin flashing. Press the CHANNEL/+ key or MAX/MIN/- key to increase or decrease the temperature reading (in increments of 0.1). Press and hold the CHANNEL/+ key or MAX/MIN/- key for three seconds to increase or decrease rapidly. Press the ALARM key to reset current value. Press the SET key switch to outdoor Temperature. To exit the temperature calibration mode at any time, press the SNOOZE/LIGHT button of the display console. If no operation is performed, the calibration mode will timeout in 30 seconds. 9.2 Calibration of Humidity Mode 17 In normal mode, press and hold the SET and MAX/MIN/- keys at the same time for five seconds to enter into the humidity calibration mode. The indoor humidity will begin flashing. Press the CHANNEL/+ key or MAX/MIN/- key to increase or decrease the humidity reading (in increments of 1%). Press and hold the CHANNEL/+ key or MAX/MIN/- key for three seconds to increase or decrease rapidly. Press the ALARM key to reset current value. Press the SET key switch to outdoor humidity. To exit the humidity calibration mode at any time, press the SNOOZE/LIGHT button on the top of the display console. If no operation is performed, the calibration mode will timeout in 30 seconds. Note: The Humidity is a difficult parameter to measure accurately and drifts over time. The calibration feature allows you to zero out this error. To calibrate humidity, you will need an accurate source, such as a sling psychrometer or Humidipaks One Step Calibration kit. 9.3 Calibration of Sensors Mode In normal mode, press and hold the SET and ALARM keys at the same time for five seconds to enter the pressure, wind gust, rainfall calibration mode. The letter CAL will appear at the bottom of the screen. 18 Press the SET key to skip over a parameter to the next.

Absolute Pressure Calibration In the calibration mode, the ABS symbol will display at the pressure section, the absolute pressure value will flash. (The default value is 0.00 inHg) Press the CHANNEL/+ key or MAX/MIN/- key to increase or decrease the absolute pressure value (in increments of 0.01 inHg). Press and hold the CHANNEL/+ or MAX/MIN/- key for three seconds to increase or decrease rapidly. Press the ALARM key to reset current value. Example: The calibrated pressure sources measure 28.37 inHg. The display console pressure reads 28.75 inHg. Offset = 28.37 - 28.75 = - 0.38 inHg

Relative Pressure Calibration In the calibration mode, press the SET key once, the REL the relative symbol will display at pressure value will flash. (The default value is 0.00 inHg) the pressure section, Press the CHANNEL/+ key or MAX/MIN/- key to increase or decrease the relative pressure value (in increments of 0.01 inHg). Press and hold the CHANNEL/+ or MAX/MIN/- key for three seconds to increase or decrease rapidly. 19 Press the ALARM key to reset current value. Example: The calibrated pressure sources measure 25.00 inHg. The display console pressure reads 24.85 inHg. Offset = 25.00 - 24.85 = 0.15 inHg Note: The display console displays two different pressures:

absolute (measured) and relative (corrected to sea-level). To compare pressure conditions from one location to another, meteorologists correct the pressure to sea-level conditions. Because the air pressure decreases as you rise in altitude, the sea-level corrected pressure (the pressure your location would be at located at sea-level) is generally higher than your measured pressure. if Thus, your absolute pressure may read 28.62 inHg (969 mb) at an altitude of 1000 feet (305 m), but the relative pressure is 30.00 inHg (1016 mb). The standard sea-level pressure is 29.92 in Hg (1013.2hpa). This is the average sea-level pressure around the world. Relative pressure measurements greater than 29.92 inHg

(1013.2hpa) are considered high pressure and relative pressure measurements less than 29.92 inHg are considered low pressure. To determine the relative pressure for your location, locate an official reporting station near from you (the internet is the best source for real-time barometer conditions, such as the website 20 of Weather.com or Wunderground.com), and set your weather station to match the official reporting station.

Wind Speed Calibration In the calibration mode, press the SET button twice and the wind speed value will flash (the default is 1.00). Press the CHANNEL/+ key or MAX/MIN/- key to adjust the wind speed calibration factor from 0.75 to 1.25, where:

Calibrated Wind Speed = Calibration factor x Measured Wind Speed Press and hold the CHANNEL/+ or MAX/MIN/- key for three seconds to increase or decrease rapidly. Press the ALARM key to reset current value. Note: The wind gust is also affected by the wind speed calibration factor. Discussion: Wind speed and wind gust are adversely affected by installation constraints. The rule of thumb is to install the weather station four times the distance of the height of the tallest obstruction (for example, a 6m(20ft) house would require an installation 24m(80ft) away). In many instances, due to trees and other obstructions, this is not possible. The wind speed calibration allows you to correct for these obstructions. 21 In addition to installation challenges, wind speed bearings (any moving part) wears over the correction value can be increased until the wind cups must be replaced. time. To correct for wear, Without a calibrated source, wind speed is a difficult parameter to measure. We recommend using a calibrated wind meter and constant, high speed fan.

Rain Calibration In the calibration mode, press the SET button three times and the rain value will flash (the default is 1.00). Press the CHANNEL/+ key or MAX/MIN/- key to adjust the rain calibration factor from 0.75 to 1.25, where:

Calibrated Rain = Calibration factor x Measured Rain Press and hold the CHANNEL/+ or MAX/MIN/- key for three seconds to increase or decrease rapidly. Press the ALARM key to reset current value. Discussion: The rain collector is calibrated at the factory based on the funnel diameter. The bucket tips every 0.01 of rain (referred to as resolution). The accumulated rainfall can be compared to a sight glass rain gauge with an aperture of at least 4. Note: that debris and insects can collect inside the tipping mechanism (they make a good spiders nest). Carefully remove the funnel and inspect the tipping mechanism for debris prior 22 to calibration. 10.Other Features of Display Console 10.1 Weather Forecasting Note: The weather forecast or pressure tendency is based on the rate of change of barometric pressure. In general, when the pressure increases, the weather improves (sunny to partly cloudy) and when the pressure decreases, the weather degrades (cloudy to rain). The weather forecast is an estimation or generalization of weather changes in the next 24 to 48 hours, and varies from location to location. The tendency is simply a tool for projecting weather changing conditions and is never to be relied upon as an accurate method to predict the weather. 10.2 Weather Icons Condition Icon Description Sunny Pressure is rising and the previous condition is partly cloudy. 23 Partly Cloudy Cloudy Rainy Pressure is falling and the previous condition is sunny or Pressure is rising and the previous condition is cloudy Pressure is falling and the previous condition is partly cloudy or Pressure is rising and the previous condition is rainy. Pressure is falling and the previous condition is cloudysnowy icon will display on rainy day and outdoor temperature below 0) 10.3 Moon Phase The following moon phases are displayed based on the calendar date. 24 10.4 Feels Like Temperature 10.4.1 Feels Like Temperature Feels like temperature is a combination of Heat Index and Wind Chill. 1. Temperatures less than 4.4C(40F), is displayed, as shown in the National Weather Service Wind Chill Table below:

the wind chill 25 2. Temperatures greater than 26.7C(80F), the heat index is displayed, as shown in the National Weather Service Heat Index Table below:
