SC088 Professional Wireless Weather Station User Manual

1. Introduction

Thank you for your purchase of the Professional Wireless Weatherstation. The following user guide provides step by step instructions for installation, operation and troubleshooting.

2. Warnings

⚠️ Warning: Any metal objects may attract a lightning strike, including your weather station mounting pole. Never install the weather station in a storm.

⚠️ Warning: Installing your weather station in an elevated location may result in injury or death. Safety goes first. Make sure your setup and preparation is secure and taking no risks.

3. Getting Started

3.4.2 Display Console Set Up

It is recommended to plug in the power supply to reduce the battery consumption and extend the service life.

Note: The sensor array must be powered and updating before powering up the console, or the console will time out searching for the sensors.

Power the console last.

Make certain the weather station sensor array is at least 10' away from the console and within 100' of the console. If the weather station is too close or too far away, it may not receive a proper signal.

Remove the battery door on the back of the display, as shown in Figure 8.

Figure 8: Console Back with Batteries and Stand

The image shows the back of the display console, the battery compartment, and the fold-out desk stand.

Insert three AAA (alkaline or lithium)) batteries in the back of the display console. The display will beep once and all of the LCD segments will light up for a few seconds to verify all segments are operating properly.

Note: The character contrast is best from a slightly elevated viewing angle.

Replace the battery door, and fold out the desk stand and place the console in the upright position.

3.4.3 Connect Sensors with Display Console

The unit will instantly display indoor temperature, humidity, pressure, tendency, moon phase, and time. The wind speed, wind gust, wind direction, rain, outdoor temperature and humidity will update on the display within a few minutes. Do not Press any menu buttons until the outside transmitter report in, otherwise the outdoor sensor search mode will be terminated. When the outdoor transmitter data has been received, the console will automatically switch to the normal mode from which all further settings can be performed.

While in the search mode, the remote search icon ? will be constantly displayed.

Note: The power adapter is intended to be correctly oriented in a vertical or floor mounted position. The prongs are not designed to hold the plug in place if it is plugged into a ceiling, under-the-table or cabinet outlet.

Figure 9: Display Console Readings

The image shows the display console with various weather readings, including outdoor temperature, indoor temperature, humidity, pressure, wind direction, and moon phase.

Note: If the power adapter is plugged in, BL ON will display in the time area for three seconds when powered up. Conversely, if the power adapter is not plugged in, BL OFF will be displayed.

3.5 Sensor Operation Verification

The following steps verify proper operation of the sensors prior to installing the sensor array.

1. Verify proper operation of the rain gauge. Tip the sensor array back and forth several times. You should hear a “clicking"sound within the rain gauge. Verify the rain reading on the display console is not reading 0.00. Each "click"represents 0.01in 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 the indoor and outdoor temperature. Verify the indoor and outdoor temperature match closely with the console and sensor array in the same location (about 9.8 ft apart). The sensors should be within 4°F (the accuracy is ±2°F). Allow about 30 minutes for both sensors to stabilize.
4. Verify proper operation of the indoor and outdoor humidity. Verify the indoor and outdoor humidity match closely with the console and sensor array in the same location (about 9.8 ft apart). The sensors should be within 10% (the accuracy is ± 5%). Allow about 30 minutes for both sensors to stabilize.

4. Weather Station Installation

4.1 Pre Installation Check.

Before installing your weather station in the permanent location, we recommend operating the weather station for one week in a temporary location with easy access. This will allow you to check out all of the functions, insure proper operation, and familiarize you with the weather station and calibration procedures. This will also allow you to test the wireless range of the weather station.

4.2 Location Survey

Perform a site survey before installing the weather station. Consider the following:

1. We recommend cleaning the rain gauge every 3 months and replacing the batteries every 3 months. Provide easyaccesstotheweatherstation.
2. Avoid radiant heat transfer from buildings and structures. In general, install the sensor array at least 5' from any building, structure, ground, or roof top.
3. Avoid wind and rain obstructions. The rule of thumb is to install the sensor array at least four times the distance of the height of the tallest obstruction. For example, if the building is 20ft (6m) tall and the monting pole is 6ft (2m) tall, install 4 x (20 – 6)' = 56ft (17m) away. Use common sense. If the weather station is installed next to a tall building, the wind and rain will not be accurate.
4. Wireless Range. The radio communication between receiver and transmitter in an open field can reach a distance of up to 300ft, providing there are no interfering obstacles such as buildings, trees, vehicles, high voltage lines. Wireless signals will not penetrate metal buildings. Most applications will only reach 100ft due to building obstructions, walls and interference.
5. Radio interference such as PCs, radios or TV sets can, in the worst case, entirely cut off radio communication. Please take this into consideration when choosing console or mounting locations.

4.3 Best Practices for Wireless Communication

Wireless communication is susceptible to interference, distance, walls and metal barriers. We recommend the following best practices for trouble free wireless communication.

1. Electro-Magnetic Interference (EMI). Keep the console several feet away from computer monitors and TVs.
2. Radio Frequency Interference (RFI). If you have other 433 MHz devices and communication is intermittent, try turning off these other devices for troubleshooting purposes. You may need to relocate the transmitters or receivers to avoid intermittent communication.
3. Line of Sight Rating. This device is rated at 300 ft line of sight (no interference, barriers or walls) but typically you will get 100 ft maximum under most real-world installations, which include passing through barriers or walls.
4. Metal Barriers. Radio frequency will not pass through metal barriers such as aluminum siding. If you have metal siding, align the remote and console through a window to get a clear line of sight.

The following is a table of reception loss vs. the transmission medium. Each "wall"or obstruction decreases the transmission range by the factor shown below.

5. Final Installation of Sensor

5.1 Integrated outdoor transmitter installation.

Professional Wireless Weather Station can be used in both the Northern and Southern Hemispheres.

Prior to installation, you will need to calibrate the wind direction.

Note: There are four alphabet letter of “N”,”E”,”S”and “W” around the wind direction, representing for the direction of North, East, South and West. Wind direction sensor has to be adjusted so that the directions on the sensor are matching with your real location. Permanent wind direction error will be introduced when the wind direction sensor is not positioned correctly during installation.

Figure 10: Northern Hemispheres Alignment

Diagrams illustrate aligning the sensor's 'S' marker with South for Northern Hemisphere setup.

5.1.1 Northern Hemispheres (NOR).

The cardinal directions (N, S, E, W) molded on the body of the outdoor sensor are indicators for the Northern Hemisphere only.

Step 1: There is a “S” indicator on the wind vane that indicates South, as shown in Figure 10. Align this “S” marker in the direction of South.

Step 2: Console operation is set to Northern Hemispheres (NOR in the time area) in Location division.

5.1.2 Southern Hemispheres (SOU) References.

For Southern Hemisphere installations, ignore the direction (N, S, E, W), and face the solar panel to the North (and in a sunny position) when it comes to install the Integrated outdoor sensor, as shown in Figure 11.

Step 1: Install the Integrated outdoor transmitter and face the solar panel to the North.

Step 2: Console operation set to Southern Hemispheres (SOU in the time area) in Location division. (Check the detailed step of setting the time area in the part 15 of Chapter 7.2)

Figure 11: Southern Hemispheres Alignment

Diagrams show orienting the solar panel towards North for Southern Hemisphere setup.

Note: The location division (NOR or SOU) on the Display Console and the directions of the sensor have to be adjusted to match with your real location.

If the wind direction sensor is not positioned correctly during installation, permanent wind direction error will be triggered.

5.1.3 Mounting & Fixing the Sensor Horizontally

Fasten the integrated outdoor sensor to the mounting pole brackets with two foot-mounting screws Ø3 bolts and M3 nuts. Then, tighten the mounting pole to your existing mounting pole with the four bolts (Ø5) and nuts (M5), or fix it on the flat surface with four tapping screws, as shown in Figure 12.

Figure 12: Horizontal Mounting Options

Diagrams illustrate horizontal mounting of the sensor array using bolts, nuts, and screws.

5.1.4 Mounting & Fixing the Sensor Vertically

Fasten the integrated outdoor sensor to the mounting pole brackets with two foot-mounting screws Ø3 bolts and M3 nuts. Then, tighten the mounting pole to your existing mounting pole with the four bolts (Ø5) and nuts (M5), or fix it on the flat surface with four tapping screws, as shown in Figure 13.

Figure 13: Vertical Mounting Options

Diagrams illustrate vertical mounting of the sensor array using bolts, nuts, and screws.

6. Low Battery Icon

A low battery indicator icon is shown in the display window for Integrated outdoor transmitter. When the low battery icon appears (the battery voltage is lower than 3.6V), replace the batteries in the sensor with fresh batteries. Be sure to never mix old and new batteries, and never mix battery types such as alkaline and lithium together.

9. Adjustment or Calibration

Note: The calibrated value can only be adjusted on the console. The 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 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.

9.1 Temperature Calibration

In normal mode, press and hold the SET and CHANNEL/+ keys at the same time for five seconds to enter the temperature calibration mode. The indoor temperature will begin flashing. Press the [+] or [-] key to increase or decrease the temperature reading (in increments of 0.1). Press and hold the [+] or [-] key for three seconds to increase or decrease rapidly. Press the ALARM key to reset current value.

Press the SET key to switch to outdoor temperature. Press the [+] or [-] key to increase or decrease the temperature reading (in increments of 0.1). Press and hold the [+] or [-] key for three seconds to increase or decrease rapidly.

Press the SNOOZE/LIGHT key to exit the calibration mode at any time. If no operation is performed, the calibration mode will timeout in 30 seconds.

9.2 Setting Calibrated Humidity

In normal mode, press and hold the SET and MIN/MAX/- keys at the same time for five seconds to enter the humidity calibration mode. The indoor humidity will begin flashing. Press the [+] or [-] key to increase or decrease the humidity reading (in increments of 1%), and press and hold the [+] or [-] key for three seconds to increase or decrease rapidly. Press the ALARM key to reset current value.

Press the SET key to switch to outdoor humidity. Press the [+] or [-] key to increase or decrease the temperature reading (in increments of 0.1). Press and hold the [+] or [-] key for three seconds to increase or decrease rapidly.

Press the SNOOZE/LIGHT key to exit the calibration mode at any time. If no operation is performed, the calibration mode will timeout in 30 seconds.

Note: 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 Setting Calibrated Pressure, wind speed and Rainfall

In normal mode, press and hold the SET and ALARM keys at the same time for five seconds to enter the pressure, wind speed and rainfall calibration mode, then wind speed icon will begin flashing. Press the [+] or [-] key to increase or decrease the wind speed reading, and press and hold the [+] or [-] key for three seconds to increase or decrease rapidly. Press the ALARM key to reset current value.

Press the SET key to switch to absolute pressure and relative pressure, and press the SNOOZE/LIGHT key to exit the calibration mode at any time. If no operation is performed, the calibration mode will timeout in 30 seconds.

1. Absolute Pressure and Relative Pressure Calibration. Press the SET key again to enter the pressure calibration mode. Press the [+] or [-] key to increase or decrease the pressure reading (in increments of 0.01inHg)

   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 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 if located at sea-level) is generally higher than your measured pressure.

   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 you (the internet is the best source for real time barometer conditions), and set your weather station to match the official reporting station.

2. Wind Speed (Gust) Calibration. Press the SET key again entering the Wind Calibration Mode, the Wind Speed Calibration value will begin flashing (the default is 1.00). Press the [+] or [-] button to adjust the wind speed calibration factor from 0.75 to 1.25, where:

Calibrated Wind Speed = Calibration factor x Measured Wind Speed

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 6 m house would require an installation 24 m 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. In addition to installation challenges, wind speed bearings (any moving part) wears over time. To correct for wear, the correction value can be increased until the wind cups must be replaced.

Without a calibrated source, wind speed is a difficult parameter to measure. We recommend using a calibrated wind meter and constant, high speed fan.

3. Rainfall Calibration (1 Hour, 24 Hour, Daily, Monthly, Total). Press the SET key again and the Rain Calibration value will begin flashing (the default is 1.00). Press the [+] or [-] button to adjust the rain calibration factor from 0.75 to 1.25, where:

Calibrated Rain = Calibration factor x Measured Rain

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 to calibration.

Press the SET key again entering the normal mode.

10. Other Console Features

The following section describes additional features and display icons.

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 conditions and is never to be relied upon as an accurate method to predict the weather.

10.2 Weather Icons

10.3 Moon Phase

The following moon phases are displayed based on the calendar date.

Figure 14: Moon Phases

10.4 Pressure Threshold Setting

The pressure threshold (the negative or positive rate of change of pressure signifying a change in the weather) can be adjusted from 2 mbar/hour to 4 mbar/hour (default level 2 mbar/hour).

The lower the level pressure threshold setting, the higher sensitivity for weather forecast changes. Locations that experience frequent changes in air pressure require a higher setting compared to locations where the air pressure is typically stagnant.

10.5 Feels Like Temperature

Feels like temperature is a combination of Heat Index and Wind Chill. At temperatures less than 40°F, the wind chill is displayed, as shown in the National Weather Service Wind Chill Table below:

Figure 15: NWS Windchill Chart

A table showing Wind Chill (°F) based on Air Temperature (°F) and Wind Speed (mph). Includes a formula for calculation and frostbite times.

At temperatures greater than 80°F, the heat index is displayed, as shown in the National Weather Service Heat Index Table below:
