on the screen displaying. If Dew Point is selected, neither Wind Chill nor Heat will be

displayed.

Alarm Mode

The Vantage Vue features 22 alarms that can be programmed to sound

whenever a reading exceeds or drops below a set value. With the exception of

barometric pressure and time, all alarms sound when a reading reaches the

alarm threshold. For example, if the high outside temperature alarm is set at

65° F/18°C, the alarm sounds when the temperature rises to or above 65.0° F/

18°C. A barometric pressure alarm is triggered based on trend. A time alarm is

based on a preset time.

Low alarms work the same way. For example, if the wind chill threshold is set

for 30°F/-1°C, the alarm condition begins when the wind chill drops to 30°F/-

1°C and will continue until the wind chill rises above 30°F/-1°C.

When an alarm condition exists, the audible alarm sounds, the alarm

icon blinks repeatedly, and an alarm description appears in the

Weather Center at the bottom of the screen. The alarm sounds for a

maximum of two minutes if the console is battery-powered, but the icon

continues to blink and the message stays in the Weather Center until you clear

the alarm or the condition clears. If you’re using the AC adapter, the alarm will

continue sounding as long as the condition exists.

The alarm will sound again for each new alarm. If more than one alarm is

active, the description for each active alarm along with a “+” symbol cycles

onto the Weather Center section of the screen every four seconds.

Vantage Vue Alarms

Special Alarms

ET (Evapotranspiration) (Optional)

ET is updated only once an hour, on the hour. If during a given hour the ET

value exceeds the alarm threshold, the ET alarm sounds at the end of that hour.

This is true for daily, monthly, and yearly ET alarms. You must have the

optional solar radiation sensor to use this alarm. See “Evapotranspiration (ET)”

on page 46 for a description of this variable.

Note: The ET Alarm is only available when the console is receiving data from a Vantage Pro2

Plus station. If your Vantage Vue console is not listening to a Vantage Pro2 Plus ISS, you

cannot set an ET alarm.

Barometric Pressure

The Vantage Vue allows you to set two barometric pressure alarms: a “rise”

alarm and a “fall” alarm. You may select any rate of change per three hours

between 0.00 and 0.25 inches (6.35 mm) Hg, (8.5 mb, hPa). The alarm will

sound if the rate of change (in either direction) exceeds the threshold you set.

This alarm is updated every minute.

Vantage Vue Troubleshooting Guide

Troubleshooting Reception Problems

While we have tested the Vantage Vue radio extensively, each site and each

installation presents its own issues and challenges. Obstructions, particularly metallic

ones, can cut down your station’s reception distance. Be sure to test reception

between the console and ISS in the locations you intend to install them before

permanently mounting your ISS.

The console’s reception status displays as an antenna icon above the graph portion of

the console screen

• The antenna icon displays with waves flashing around it when the

console is receiving data from the ISS.

• The antenna icon displays alone when the console is trying to re-

establish a lost connection. When no data packets have been received

for 10 minutes, the console dashes-out any missing sensor readings.

• The antenna icon disappears when the connection between the ISS and console is

lost. The console tries for 10 minutes to re-establish a connection, then stops trying

to connect with the ISS for 15 minutes, and then redisplays the antenna alone

Dew

Dew Point reading

seems too high or too

low

Check calibration numbers for temperature. Dew point depends on

outside temperature and humidity. Make sure both sensors are

working.

Temperature

Outside temperature

reading seems too high

Check calibration number and adjust if necessary. The ISS may

need to be relocated away from radiant heat sources. See the ISS

Installation manual.

Inside temperature

sensor reading seems

too high

Move the console out of direct sunlight. Make sure the console or

sensor is not in contact with an exterior wall that heats up in

sunlight or when outside temperature rises. Make sure the console

or sensor is not near a heater or other internal heat source (lamps,

appliances, etc.). Check calibration number and adjust if

necessary.

Outside temperature

seems too low

Check calibration number and adjust if necessary. Sprinklers may

be hitting the ISS radiation shield. Relocate. See ISS manual.

Inside temperature

sensor reading seems

too low

Make sure the console temperature sensor is not in contact with

an exterior wall that cools down when outside temperature drops.

Make sure the console temperature sensor is not near an air con-

ditioning vent. Check calibration number and adjust if necessary.

Chill

Wind chill reading

seems too high or too

low

Check calibration numbers for temperature. Wind chill depends on

temperature and wind speed. Make sure they’re working.

Heat

Heat Index reading

seems too high or too

low

Check calibration numbers for temperature. The heat index

depends on temperature and outside humidity. Make sure the sen-

sors are working.

Rain

No rain readings Make sure the rain funnel is not clogged with debris. See the ISS

manual.

Time

Incorrect times for

sunrise and sunset

Check your latitude, longitude, time zone, and daylight saving time

settings. Sunrise and sunset times are calculated from the console

using all of these settings.

Problem Solution

Console Diagnostic Mode

while it tries to re-establish a connection with the ISS. Enter and exit Setup Mode

to re-display the antenna icon and manually force the console to re-establish a

connection with the ISS.

Check Console Reception

Enter Setup Mode by pressing and releasing 2ND and pressing SETUP. Keep pressing

DONE until the Receiving From screen displays. (See “Screen 5: Active Transmitters”

on page 8 for more information.) Wait a few minutes while the console lists all the

stations transmitting within range. If the console does not detect your transmitter,

check the following:

• Adjust the console antenna so that it is vertical and in line of sight the Vantage

Vue ISS antenna.

Note: The ISS antenna for the Vantage Vue can not be adjusted. Ensure that the console antenna

is vertical.

• Check the ISS and transmitter ID numbers. See“Screen 6: Configuring Transmitter

IDs” on page 9.

• Try reducing or increasing the distance between the ISS and the console. They

should be at least 10 feet /3 meters apart. Maximum range is 1000’ (300m).

Refer to the ISS Installation Manual for instructions on how to check the station for

potential transmission problems.

Console Diagnostic Mode

In addition to logging weather data, the console continuously monitors the station’s

radio reception. You may find this information very helpful, especially when you are

choosing locations for your console and ISS.

The Console Diagnostics Mode consists of two screens, the Statistical Diagnostic

Screen and the Reception Diagnostic Screen.

Note: Radio transmission data used by the diagnostic screens clears each day at midnight, except

for good packet graph data. Diagnostic screens are also cleared if you change your ID or go

into the Setup Mode.

Diagnostic Screen Commands

• Press and hold TEMP, then press HUM to display the Statistical Diagnostic

screen.

• Press 2ND and then press CHILL to toggle between the Statistical and Reception

Diagnostic screens.

• Press DONE to exit the diagnostic screens.

• A degree (°) sign displays to the right of the last digit in Value 3 (in the area of the

compass rose, see illustration below) of the Reception Diagnostic screen (Screen 2)

to differentiate which screen is currently displayed.

Console Diagnostic Mode

Screen 1: Statistical Diagnostic Screen

The Statistical Diagnostic Screen displays information about how well data is being

received from the weather station to the console. The information that is displayed in

this screen includes:

Note: Several of these values, with a *, are used by Davis engineers.

1. Time of day or number of times the anemometer reed switch was seen closed*.

The reed switch closes once each revolution of the anemometer wind cups. Press

WIND to toggle between these two values.

2. Date or the number of times the anemometer reed switch was seen open*. Press

WIND to toggle between these two values.

Note: The time and date displays can be toggled in both statistical and reception diagnostic

screens.

3. Number of packets containing received “Cyclical Redundancy Check” (CRC)

errors. The system runs a CRC check on data packets. Any data packets that don’t

pass this check are considered to contain errors and are discarded. These are

considered bad packets. This also includes the CRC errors received during radio

acquisition.

4. The firmware version currently installed on the console.

5. Maximum number of bad packets in a row without resynchronization.

6. Number of times the console resynchronized with the transmitter. The console will

attempt to resynchronize with the station after 20 consecutive bad packets.

7. Percentage of good packets received. Graph shows the current and last 25 days of

good packet percentage data. The scale is fixed at 10% per dot.

8. The total number of bad data packets including missed packets and CRC errors.

Missed packets are described as when a data packet is expected, but is not

recognized as a data packet by the console. This does not include bad packets

received during acquisition.

9. Current streak of consecutive bad packets. The counter increments when the

console is synchronized but the packet is bad. This value is reset to zero when a

good packet is received.

10.Current streak of consecutive good packets received.

displayed is the repeater that the console is set to receive. If the console is not

listening to repeaters, this section remains blank.

14.Total number of good packets received.

15.Longest streak of consecutive good packets.

Screen 2: Reception Diagnostic Screen

The Reception Diagnostic screen displays information pertinent to the console’s

wireless reception. To view this screen from the Statistical Diagnostic screen, press

2ND and then press CHILL. The degree sign displaying to the right of the last digit in

Value 1 (see illustration below) verifies that the Reception Diagnostic screen is

currently displayed.

The information that is displayed in this screen includes:

1. 8-bit timer value of next reception.*

2. Radio frequency error of the last packet received successfully. The ideal number

should be zero after frequency correction is added. This value affects the value of

#3.

3. Current frequency correction factor. Shows the frequency adjustment to the

console.

4. Signal strength of the last packet received. The values displayed in this field show

the received signal strength in dBm power. A more negative number means the

signal strength is weaker while a less negative number means the signal strength is

stronger. (Range: -100 to -20.) If a packet is not received successfully, the signal

strength field is dashed out (--).

5. The number of times that the Phase Lock Loop did not lock.*

6. Percentage of good data packets. Graph shows the current and last 25 days of good

packet percentage data. The scale is fixed at 10% per dot.

7. Frequency index of the next packet to be received.*

8. Background noise level. This refers to the signal level that the console hears while

it is not listening to a transmitter. Background noise is displayed as power level in

Console Maintenance

dBm. The more negative the number is, the lower the background noise is.

(Typically, this number should be about 15 lower than signal strength.)

9. Current console battery voltage. Ignore this value if using only an AC adapter to

power the console. The value is dashed out (--) if no batteries are installed.

Console Maintenance

Changing Batteries

Use this procedure to change console batteries without losing any stored weather

data or console configuration settings.

1. Plug in the AC adapter or, if the AC adapter is not present.

2. Enter Setup Mode by pressing and releasing 2ND and pressing SETUP.

Entering Setup Mode makes sure the station isn’t writing any data to memory

when power is removed.

3. Remove the battery cover located on the back of the console by pressing down on

the two latches at the top of the cover.

4. In the top battery compartment, insert a fingertip between the battery and the

notched end of the compartment and remove the battery.

5. Repeat the process for the batteries in the bottom battery compartment.

6. Install the new batteries. (See “Installing Batteries” on page 3.)

7. Replace the battery cover and remove the AC power adapter, if desired.

Appendix A

Weather Data

Refer to this appendix to learn more about the weather variables that are measured,

displayed, and logged by your Vantage Vue station. The following variables are

arranged below in the order they are viewed on the console screen: left to right, top to

bottom, starting with time.

Time

A built-in clock and calendar track the time and date. The console automatically

adjusts for daylight saving time and leap year in most of North America, and Europe

(and allows manual adjustment elsewhere). The console also displays the sunrise and

sunset times based on the latitude and longitude, time and date, and your time zone/

UTC offset.

Moon Phases

The moon phase icons and moon phase description in the Weather Center section of

console screen are calculated based on latitude and longitude, time and date and your

time zone/UTC Offset. The following table displays the moon phase for the Northern

and Southern Hemispheres.

Forecast

The forecast icons show what weather conditions may occur within the next 12 hours.

The console generates a weather forecast based on the barometric reading and trend;

wind speed and direction; rainfall; temperature; humidity; latitude and longitude;

and time of year. The forecast is updated once an hour, on the hour and requires three

hours of data. Predictions are made for cloud cover and the likelihood of

precipitation.

Wind

The anemometer measures wind speed and direction, and is part of the Integrated

Sensor Suite (ISS). The console calculates a 2-minute average wind speed, a 10-minute

average wind speed and 10-minute dominant wind direction. The 10- and 2-minute

average wind speed is displayed in the Weather Center whenever wind has been

selected on the console. The last six 10-minute dominant wind directions are included

in the compass rose wind display.

Beaufort Scale

The Beaufort Scale is an empirical measure for describing wind speed which ranks

wind speeds in classes. The Beaufort Scale classification for the current wind

condition is listed in the Weather Center when WIND is pressed and WxCEN is

pressed several times. See “Wind Speed and Direction” on page 17 for more

information.

Temperature

The ISS houses the outside temperature sensor in a vented and shielded enclosure

that minimizes solar radiation induced temperature error. The console houses the

inside temperature sensor.

Humidity

Humidity itself simply refers to the amount of water vapor in the air. However, the

total amount of water vapor that the air can contain varies with air temperature and

pressure. Relative humidity takes into account these factors and offers a humidity

reading which reflects the amount of water vapor in the air as a percentage of the

amount the air is capable of holding. Relative humidity, therefore, is not actually a

measure of the amount of water vapor in the air, but a ratio of the air’s water vapor

content to its capacity. When we use the term humidity in the manual and on the

screen, we mean relative humidity.

It is important to realize that relative humidity changes with temperature, pressure,

and water vapor content. If a parcel of air with a capacity for 10 g of water vapor

contains 4 g of water vapor, the relative humidity would be 40%. Adding 2 g more

water vapor (for a total of 6 g) would change the humidity to 60%. If that same parcel

of air is then warmed so that it has a capacity for 20 g of water vapor, the relative

humidity drops to 30% even though water vapor content does not change.

Relative humidity is an important factor in determining the amount of evaporation

from plants and wet surfaces since warm air with low humidity has a large capacity

to absorb extra water vapor.

Wind Chill

Wind chill takes into account how the speed of the wind affects our perception of the

air temperature. Our bodies warm the surrounding air molecules by transferring heat

from the skin. If there’s no air movement, this insulating layer of warm air molecules

stays next to the body and offers some protection from cooler air molecules.

However, wind sweeps that warm air surrounding the body away. The faster the

wind blows, the faster heat is carried away and the colder you feel. Wind has a

warming effect at higher temperatures.

Note: There is no windchill when the air temperature is at or above 93° F (-34° C).

Heat Index

The Heat Index uses temperature and the relative humidity to determine how hot the

air actually “feels.” When humidity is low, the apparent temperature will be lower

than the air temperature, since perspiration evaporates rapidly to cool the body.

However, when humidity is high (i.e., the air is more saturated with water vapor) the

apparent temperature “feels” higher than the actual air temperature, because

perspiration evaporates more slowly.

Note: Heat Index and air temperature are equal at or below 0° F (-18° C).

Dew Point

Dew point is the temperature to which air must be cooled for saturation (100%

relative humidity) to occur, providing there is no change in water vapor content. The

dew point is an important measurement used to predict the formation of dew, frost,

and fog. If dew point and temperature are close together in the late afternoon when

the air begins to turn colder, fog is likely during the night. Dew point is also a good

indicator of the air’s actual water vapor content, unlike relative humidity, which takes

the air’s temperature into account. High dew point indicates high water vapor

content; low dew point indicates low water vapor content. In addition a high dew

point indicates a better chance of rain, severe thunderstorms, and tornados.

You can also use dew point to predict the minimum overnight temperature. Provided

no new fronts are expected overnight and the afternoon relative humidity is greater

than 50%, the afternoon’s dew point gives you an idea of what minimum temperature

to expect overnight. The higher the humidity is, the more accurate the dew point

prediction.

Note: Dew Point is equal to the air temperature when the humidity is 100%.

Rain

Vantage Vue incorporates a tipping spoon rain collector in the ISS that measures 0.01''

or 0.2 mm for each tip of the spoon. Your station logs rain data in the same units it is

measured in and converts the logged totals into the selected display units (inches or

millimeters) at the time it is displayed. Converting at display time reduces possible

compounded rounding errors over time.

Four separate variables track rain totals: “rain rate,” “daily rain,” “monthly rain,” and

“yearly rain.” Rain rate calculations are based on the interval of time between each

spoon tip, which is each 0.01'' or 0.2 mm rainfall increment.

Barometric Pressure

The weight of the air that makes up our atmosphere exerts a pressure on the surface

of the earth known as atmospheric pressure. Generally, the more air above an area,

the higher the atmospheric pressure. This means that atmospheric pressure changes

with altitude. For example, atmospheric pressure is greater at sea level than on a

mountaintop. To compensate for this difference and facilitate comparison between

locations with different altitudes, atmospheric pressure is adjusted to the equivalent

sea level pressure. This adjusted pressure is known as barometric pressure. In reality,

the Vantage Vue measures atmospheric pressure. When you enter your location’s

altitude in Setup Mode, the Vantage Vue stores the necessary offset value to

consistently translate atmospheric pressure into barometric pressure.

Barometric pressure also changes with local weather conditions, making barometric

pressure an extremely important and useful weather forecasting tool. High pressure

zones are generally associated with fair weather while low pressure zones are

generally associated with stormy weather. For forecasting purposes, however, the

value of the absolute barometric pressure is generally less important than the change

in barometric pressure. In general, rising pressure indicates improving weather

conditions while falling pressure indicates deteriorating weather conditions.

Evapotranspiration (ET)

Evapotranspiration (ET) is a measurement of the amount of water vapor returned to

the air in a given area. It combines the amount of water vapor returned through

evaporation (from wet surfaces) with the amount of water vapor returned through

transpiration (exhaling of moisture through plant stomata) to arrive at a total.

Effectively, ET is the opposite of rainfall, and it is expressed in the same units of

measure (inches, millimeters).

The Vantage Vue uses air temperature, relative humidity, barometric pressure,

average wind speed, and solar radiation data to estimate ET, which is calculated once

an hour on the hour. Measuring ET requires that the Vantage Vue console listen to a

an optional Vantage Pro2 Plus station with a solar radiation sensor installed.

Solar Radiation

What we call “current solar radiation” is technically known as Global Solar Radiation,

a measure of the intensity of the sun’s radiation reaching a horizontal surface. This

irradiance includes both the direct component from the sun and the reflected

component from the rest of the sky. The solar radiation reading gives a measure of the

amount of solar radiation hitting the solar radiation sensor at any given time,

expressed in Watts/sq. meter (W/m2). Measuring solar radiation requires that the

Vantage Vue console listen to an optional Vantage Pro2 Plus station with a solar

radiation sensor installed. Solar Radiation is displayed in the Weather Center when

ET is pressed and WxCEN is pressed multiple times.

UV (Ultra Violet) Radiation

Energy from the sun reaches the earth as visible, infrared, and ultraviolet (UV) rays.

Exposure to UV rays can cause numerous health problems, such as sunburn, skin

cancer, skin aging, cataracts, and immune system suppression. Measuring UV radia-

tion requires that the Vantage Vue console listen to an optional Vantage Pro2 Plus sta-

tion with a UV radiation sensor installed. The UV Index is displayed in the Weather

Center when ET is pressed and WxCEN is pressed multiple times.

*Outside temperature accuracy is based on the temperature sensor itself and not on the sensor and the passive shielding

together. The solar radiation induced error for the radiation shield: +4F (2C) at solar noon with the wind speed at less than

or equal to 2 mph (1 ms); The higher the wind speed, the less solar radiation induced error.

**Barometric pressure readings are standardized to sea level. Elevation Range: -1500’ to +15,300’; -430 to

+4660 m. Note: The console screen limits display of lower elevation to -999’ when using feet as elevation unit.

***This is the reduced value after standardizing to sea level.

Wireless Repeater Configuration

Vantage Pro2 Wireless Repeaters (#7626, #7627) or Long-Range Wireless Repeaters

(#7653, #7654) can be added to increase transmission distances or improve

transmission quality between a station and a console. A repeater receives information

transmitted from a Vantage Vue or Vantage Pro2 station and retransmits it to a

console. Depending on transmission distance, one repeater or several repeaters can be

used to collect and retransmit weather data.

All consoles communicating with repeaters must be set up with the correct

Transmitter ID and Repeater ID before the console can correctly receive station

information.

Setting Repeater ID

To set Repeater ID on the console:

1. Press 2ND and SETUP to enter Setup Mode.

2. Press DONE to display Screen 6: Configuring Transmitter IDs.

See “Screen 6: Configuring Transmitter IDs” on page 9 for more information on

configuring Transmitter IDs.

3. Press 2ND and then WIND to turn the repeater function on and to select a

Repeater ID. Pressing 2ND and WIND sets the console to receive the signal from a

repeater instead of directly from a station. The first Repeater ID displayed is

repeater A.

4. Press WIND repeatedly to cycle through all eight repeater IDs possible or to clear

the repeater ID in the right hand corner. When no repeater ID is shown, the console

is configured to listen directly to a station and not to a repeater.

In this example, the console

is set up to receive from an

ISS station on transmitter

ID 1 from repeater A.

5. Press DONE to continue to

the other screens in the

Setup Mode, or press and

hold DONE to return to the Current Weather Mode.

Clearing Repeater ID

If a repeater ID is being displayed in Screen 6 and you are not using a repeater, you

must turn off the repeater function to receive station information successfully.

In Setup Screen 6:

Press 2ND and then press WIND repeatedly so that the console cycles through the list

of repeater IDs (Repeaters A-H) until the section where the repeater ID was displayed

is blank. Press DONE to continue to the next screen or press and hold DONE to

return to the Current Weather Mode.
