4.6.2 DisplayConsoleSetUp

Note: Power up the rain gauge, anemometer and thermos-hygrometer sensors first before

powering up the console. If you power up the console first, you will need to resynchronize the

sensors.

Make certain the weather station sensors are at least 10’away from the console and within

100’of the console. If the weather station is too close or two far away, it may not receive a proper

signal. If you have more than one thermo-hygrometer transmitter, make sure they are all powered

up and transmitting on different channels.

1. Remove the battery door on the back of the console, as shown in Figure 12.错误！未找到引用

源。2. Insert four AA 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. The console will cycle through a spectrum of colors.

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

Figure 12

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

position.

The console will instantly display indoor temperature, humidity, pressure, 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 reports 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.

If you have more than one thermo-hygrometer sensor (up to eight thermo-hygrometer sensors

are supported), the display will automatically toggle between sensors until all sensors have

reported in.

If it does not update, please reference the troubleshooting guide in Section 12.

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 13

Note: If the power adapter is plugged in, AC ON will display in the time area for three

seconds when powered up. Conversely, if the power adapter is not plugged in, AC OFF will

be displayed.

4.6.3 SensorOperationVerification

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

• 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 0.01 inches of rainfall.

• 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.

• 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

10’apart). The worst case sensor accuracy should be within 4°F worst case (the accuracy is

±2°F). Allow about 30 minutes for both sensors to stabilize.

• 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

10’apart). The worst case sensor accuracy should be within 10% (the accuracy is ± 5%).

Allow about 30 minutes for both sensors to stabilize.

5 WeatherStationInstallation

5.1 PreInstallationCheckout

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.

5.2 SiteSurvey

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

1. You must clean the rain gauge every few months and change the rechargeable batteries

every 2-3 years. Provide easy access to the rain gauge.

2. Avoid radiant heat transfer from buildings and structures. In general, install the

thermos-hygrometer in a shaded area on the north side of a structure.

3. Avoid wind obstructions. The rule of thumb is to install the anemometer at least four

times the distance of the height of the tallest obstruction. For example, if the building is

20’ tall, and the mounting pole is 6’ tall, install 4 x (20 – 6)’ = 56’ away.

4. Wireless Range. The radio communication between receiver and transmitter in an open

field can reach a distance of up to 300 feet, providing there are no interfering obstacles

such as buildings, trees, vehicles, high voltage lines. Wireless signals will not penetrate

metal buildings. Under most conditions, the maximum wireless range is 100’.

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. Make sure your display console is at least five feet away from any

electronic device to avoid interference.

6. Visit Ambient Weather Mounting Solutions for assistance and ideas for mounting your

weather station:

http://www.ambientweather.com/amwemoso.html

5.3 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 300feet line of sight (no interference, barriers or

walls) but typically you will get 100feet 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”orobstruction

decreases the transmission range by the factor shown below.

Medium RF Signal Strength Reduction

Glass (untreated) 5-15%

Plastics 10-15%

Wood 10-40%

Brick 10-40%

Concrete 40-80%

Metal 90-100%

6 FinalSensorInstallation

6.1 AnemometerInstallation

Prior to installation, you will need to calibrate the wind direction. There is a “S” indicator on the

wind vane that indicates South, as shown in Figure . Align this “S” marker in the direction of

South.

Figure 14

Fasten the wind transmitter to mounting pole brackets with foot-mounting, two ׎3 bolts and M3

nuts, as shown in Figure 13.

Figure 13

Tighten the included mounting pole to your mounting pole (purchased separately) with the four ׎5

Bolts and M5 Nuts assembly, or fix on the wall with four tapping screws, as shown in Figure 14.

Figure 14

6.2 RainGaugeInstallation

Figure 15

Remove the rain gauge funnel from the base prior to installation by rotating the counter clockwise

until the tabs on the base and the funnel align, then pulling upwards.

Fasten the rain gauge to the mounting pole, as shown in Figure 16.

Figure 16

Tighten the rain gauge to your mounting pole or bracket with two U-bolts and four M5 nuts , or fix

on a horizontal surface with the four tapping screws, as shown in Figure 17.

Reattach the funnel by aligning the tabs on the funnel and base, and rotate clockwise.

Figure 17

6.3 ThermoHygrometerInstallation

It is recommended you mount the remote sensor outside in a shaded area. A north facing wall is

preferred because it is in the shade most of the day. Direct sunlight and radiant heat sources will

result in inaccurate temperature readings. Although the sensor is water resistant, it is best to mount

in a well protected area, such as under an eve. Use a screw or nail (not included) to affix the

remote sensor to the wall, as shown in Figure 0.

Note: If plugged into AC power, the time area will display AC ON and the backlight will

remain on. It is not recommended leaving the backlight on for a long period of time when

operating on batteries only, or the batteries will run down quickly.

7.10 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.

The WS-12 supports up to eight remote sensors. Each of the eight sensors can be calibrated.

If you own more than one remote sensor, press the CHANNEL/+ button first to display the

specific channel you wish to calibrate.

7.10.1 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 switch to next channel (1through 8). To exit the 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.

7.10.2 HumidityCalibration

In normal mode, press and hold the SET and HISTORY/- 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%).

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 switch to next channel (1through 8). To exit the 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: 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.

7.10.3 WindSpeed,Rainf allandBarometricPressure

Calibration

In normal mode, press and hold the SET and ALARM keys at the same time for five seconds to

enter the wind speed, rainfall and pressure calibration mode. The wind speed will begin flashing.

Press the [+] or [-] key to increase or decrease the wind speed reading. 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 switch to rainfall, absolute pressure and relative pressure. To exit the

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.

1. Wind Speed (Gust) Calibration. After entering the Calibration Mode, the Wind Speed

Calibration gain will begin flashing (the default is 1.0). 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.

2. 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 1.0). 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.

3. Absolute Pressure and Relative Pressure Calibration. Press the SET key again to enter the

absolute pressure and relative 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, such as Weather.com or

Wunderground.com), and set your weather station to match the official reporting station.

9.3 PersonalizingColorRanges

You can customize your background color ranges to suit your location, or personal preferences.

For example, if you live in Alaska, your definition of hot and cold may be very different if you

live in Arizona.

Likewise, if you track your indoor comfort level, your comfort range may be very different than

someone else.

Example 1: I live in Arizona, and the temperature ranges from 20 °F to 110 °F.

Color Increment = (HI-LOW)/9 = (110 – 20)/9 = 10 °F.

Example 2: I live in Alaska, and the temperature ranges from -20°F to 70°F.

Color Increments = (HI-LOW)/11 = (70 – (-20))/9 = 10 °F.

9.4 LowBatteryIcon

A low battery indicator icon is shown in the display window for each sensor. When the low battery

icon appears (the battery voltage is lower than 2.4V), replace the batteries in the sensor with fresh

and lithium together.

10 GlossaryofTerms

Term Definition

Accuracy Accuracy is defined as the ability of a measurement to match the

actual value of the quantity being measured.

Hygrometer A hygrometer is a device that measures relative humidity. Relative

humidity is a term used to describe the amount or percentage of

water vapor that exists in air.

Range Range is defined as the amount or extent a value can be measured.

Resolution Resolution is defined as the number of significant digits (decimal

places) to which a value is being reliably measured.

Wind Vane A wind vane is a device that measures the direction of the wind. The

wind vane is usually combined with the anemometer. Wind direction

is the direction from which the wind is blowing.

Absolute Barometric

Pressure

Relative barometric pressure, 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

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.

Relative Barometric

Pressure

Measured barometric pressure relative to your location or ambient

conditions.

HectoPascals (hPa) Pressure units in SI (international system) units of measurement.

feet and 100 feet under most conditions. Move the sensor

assembly closer to the display console.

If the sensor assembly is too close (less than 5’), move

the sensor assembly away from the display console.

Make sure the remote sensor LCD display is working

and the transmitter light is flashing once per 60 seconds.

Install a fresh set of batteries in the remote

thermo-hygrometer. For cold weather environments,

install lithium batteries.

Make sure the remote sensors are not transmitting

through solid metal (acts as an RF shield), or earth

barrier (down a hill).

Move the display console around electrical noise

generating devices, such as computers, TVs and other

wireless transmitters or receivers.

Move the remote sensor to a higher location. Move the

remote sensor to a closer location.

Temperature sensor reads too high in the

day time.

Make sure the thermo-hygrometer is mounted in a

shaded area. The pre preferred location is a north facing

wall because it is in the shade most of the day.

Consider the following radiation shield if this is not

possible:
