VIRTUAL WEATHER STATION BASE EDITION FEATURES
THE ASSISTANT Menu Shortcut: Help Assistant If you are a new user, it is advisable that you completely run through the assistant to understand all of the features of Virtual Weather Station. When Virtual Weather Station is launched for the first time, the Assistant will automatically be displayed.
CONVERSIONS Menu Shortcut: Settings Conversions You may select the units of measurement in which the data is displayed throughout the software. All program windows and files will display these units.
CALIBRATION Menu Shortcut: Settings Calibration Virtual Weather Station allows you to calibrate for improved accuracy. In addition, if your wind speed sensor is below the expected reading due to bearing life or trees obstructing the anemometer, these errors can be adjusted to provide realistic values. The calibration takes the form of the following equation: Calibrated Value = Gain x Measured Value + Offset
The table provides solutions for typical measurement problems: PROBLEM The wind speed is reading 50% lower than it should be because the sensor is obstructed by trees. In other words, when the wind speed reads 4.8 km/h (3 mph), it is actually 9.6 km/h (6 mph). One of my temperature sensors is off by 3 I installed my anemometer incorrectly, and when it point s north, it should measure south SOLUTION Set the wind speed gain to 2.00.
Set the temperature offset to 3.00 Set the wind direction offset to 180.00
Changing the calibration settings in Virtual Weather Station will not adjust the parameters displayed from the console. Setting the gain to 0 will cause the value to always read 0. Only set the gain to 0 if you do not have the sensor in your system. PRECISION Menu Shortcut: Settings Precision Precision is the number of decimal places that Virtual Weather Station allows you to customize for each variable unless otherwise noted on specific display panels. For example, a precision of two would be represented as 3.14, and a precision of three would be represented as 3.141. These precision values are represented in files, HTML tags and other various displays. The precision can be changed for the values (which include averages) and rates of change. Changing the precision for the temperature will change all of the temperatures (i.e., indoor and outdoor).
COMMUNICATION Menu Shortcut: Communication Communication WEATHER STATION Select Oregon Scientific WMR968, WMR918 (wireless) from the list to connect to the WMR928N or WMR928NX weather stations. If you do not own a weather station, select the Stationless mode of operation. COMMUNICATION PORT Select the communication port. Refer to the section on TROUBLESHOOTING for more information on selecting the correct communication port if you are unsure. COMMUNICATION RATE Specify the communication rate at which Virtual Weather Station with the weather station. If the computer performance is poor, try increasing this value.

REAL-TIME DATA Virtual Weather Station continuously collects data from your weather station. The sample rate varies based on your weather station's specifications. See your weather station user manual for specifics on the sample rate.

ADVANCED PARAMETER SETTINGS
Menu Shortcut: Settings Advanced Parameter Settings Virtual Weather Station provides a number of advanced parameter settings. ADVANCED PARAMETER SETTINGS Degrees Days Heating and Cooling DESCRIPTION Because temperature plays an important part in the rate of development of plants and many pests, a measurement that takes into account the accumulation of heat with passing time is important to predict maturation. Degree-days provide a measure for calculating the effects of temperature on the development of plants or pests. One degree-day is the amount of heat that accumulates when the temperature remains one degree above the threshold for one day. One degree-day is also the amount of heat that accumulates when the temperature is 24 degrees above the threshold for one hour. Heating Threshold = the threshold for calculating degree-days heating. Cooling Threshold = the threshold for calculating degree-days cooling. Wind run is the distance wind has traveled. For example, the wind run for a constant wind speed of 32 kilometers per hour (20 miles per hour) for 2 hours is 64 kilometers (40 miles), or: Wind Run = Wind Speed * Time There may be wind run calculation problems with specific computers due to the microprocessor and other hardware devices. If you find the wind run values are out of range, place the following line in your win.ini file: wuseDefaultTimer=True. To reset these values, select Settings Recall Daily, Monthly and Yearly and edit the wind run for the day, month and year. Virtual Weather Station will calculate the pressure trend based on your own specified threshold. If the rate of change of pressure is above or below this threshold, Virtual Weather Station will report a rising / falling pressure trend. You can override your stations default wind gust calculation method and select the maximum within a specified number of samples. The time constant for the filtered average can be varied. The filter is based on a low pass filter differential equation. The output value reaches 63% of the input value after one time constant (the default time constant is 60 minutes or one hour), and will reach 95% of the input value after five time constants (default = 300 minutes or five hours).

Wind Chill Calculation

The wind chill calculation formula makes use of advances in science, technology, and computer modeling to provide a more accurate, understandable, and useful for calculating the dangers from winter winds and freezing temperatures. In addition, clinical trials have been conducted and the results of those trials have been used to verify and improve the accuracy of the new formula.
RAINFALL SETTINGS Menu Shortcut: Settings Rainfall Some stations calculate the daily and monthly rain. In the event the daily and monthly rain is not calculated by the weather station, the daily rain is calculated by subtracting the minimum daily rain from the maximum daily rain. To change the daily, monthly or yearly rain, you must calculate the difference between the daily maximum and minimum rain, and enter it in the minimum rain field. The daily rain is stored by Virtual Weather Station as the difference between the maximum daily rain and the minimum daily rain, or: Daily Rain = Maximum Daily Rain - Minimum Daily Rain. The same is true for monthly and yearly rain. Changing the daily rain does not change the monthly or yearly rain automatically.
DOMINANT WIND DIRECTION COUNTER Menu Shortcut: Settings Dominant Wind Direction Virtual Weather Station calculates the dominant wind direction based on the day, month and year. The wind direction is only counted when the wind speed is greater than 0. The dominant wind direction values can be edited.
RESETTING DAILY MINIMUM AND MAXIMUM VALUES Menu Shortcut: Settings Reset Min and Max
You can reset the daily minimums and maximums at any time by selecting the OK button. COMPLETE PARAMETER LIST Menu Shortcut: Window Complete Parameter List
You can view a complete list of the parameters (1) measured by your weather station, (2) calculated by your weather station and retrieved by Virtual Weather Station, or (3) calculated by Virtual Weather Station. OPTION Daily Highs and Lows Average Values DESCRIPTION Virtual Weather Station calculates daily highs and lows. Note that Virtual Weather Station must be running for the daily highs and lows to be recorded. Virtual Weather Station calculates average values for all weather parameters based on a one-hour time period. When Virtual Weather Station is restarted, the average values are reset to the current value.
RATE OF CHANGE VALUES Virtual Weather Station calculates rate-of-change values for all weather parameters based on a one-hour time period. Like the daily highs and lows, Virtual Weather Station must be running for rate of change values to be recorded. When Virtual Weather Station is restarted, the rate-of-change values are reset to zero. Available sensors vary based on your weather station. See the WMR928NX weather station manual for more details. DAILY, MONTHLY AND YEARLY SUMMARY Virtual Weather Station provides a daily, monthly and yearly summary. The high, low, averages and integrated values are recorded as well as the time and date of the highs and lows. You can edit the daily extremes.

If your microprocessor is overheating, you may receive this message from the operating system. Keep your computer in a cool place to reduce crashes Some low power mode or power savers will cause the program to crash when communicating to the serial port. Turn off the power saver by selecting Right Click on the desktop, Properties, Screen Saver, Settings (Energy Savings Features of Monitor), and Turn off monitor. Your graphics or display card driver may be outdated or incompatible. Virtual Weather Station uses high resolution graphics that all display drivers must support. However, display cards and their associated drivers are notorious for incompatibilities with the Windows operating system. You can determine your graphics card manufacturer by selecting Right Click on the desktop, then Display Properties Settings Advanced Properties. You may be able to download the latest graphics driver from the manufacturer by performing a search on the adapter part number and chip type. You have an IRQ conflict between the serial port and the mouse. The solution is to replace your serial mouse with a bus mouse that resides on IRQ-12. This is not a problem with the software but is a hardware conflict associated with your computer. For more on IRQs, see Microsoft's troubleshooting hints. Verify that the time zone is entered correctly. Verify that the longitude and latitude are entered properly. Make sure you do not have the latitude and longitude switched Verify that the hemisphere settings are correct. The celestial calculator is a close approximation of the sunrise and sunset in your location and may be inaccurate by several minutes due to equation inaccuracy or your altitude (the equations are based on sea-level). You can account for this inaccuracy by entering a number in the offset (-60 minutes to +60 minutes). This problem may be related to the operating system's daylight savings time clock. The clock may not be available on your system. To account for this problem, enter an offset of +60 minutes or -60 minutes. Strip charts are intended for plotting data "real-time" and the data is not saved permanently to a file. Reference the section on graphs vs. strip charts. Virtual Weather Station must be running to record daily highs and lows (data not stored in your weather station's memory). Rate of change is set to zero when Virtual Weather Station is started. Virtual Weather Station calculates the rate of change by calculating the
The Sunrise and Sunset Times are Incorrect
Sunrise and sunset are off by one hour, or did not change with the Daylight Savings Time Change. The strip charts lose the data when the program is shut down The minimum and maximum daily values are not correct Rate of changes are not correct

SOLUTION derivative of a parameter, and then filtering it over one hour. Thus, the rate of change equation factors all of the measurements taken in the last hour, and may not exactly match the change in one hour. Determining the actual change in one hour would require every measurement within the hour to be saved, which is not practical, and would require the software to be operational for more than one hour. Instead, Virtual Weather Station uses calculation techniques standard in the engineering community for calculating rate of change. Virtual Weather Station's rain rate may not agree with the rain rate calculated by the weather station because different techniques are used. Change the precision from the display's attributes panel. For example, changing the precision to three will add three numbers to the right of the decimal point (1/1000ths). Power save mode must be turned off to prevent distorted images Virtual Weather Station prefers to run at High Colour or 16 bit. Select Start Settings Control Panel from the windows menu bar and select [Display][Settings] and High Colour. Select Program Settings Program Settings and set the CPU resources to Low. Select Internet FTP General Settings and set the FTP Priority to Below Normal and select the Max CPU During FTP to OFF. Select Communication][Communiaction], and set the Communication Rate (sec) to 3.0 seconds or greater. You may be low on memory. Reduce the number of graphical images displayed. Reduce the number of displays. Too many displays may result in insufficient memory. Reduce the length of time in your graphs. Select Plot Last x hours. Enter a number less than 240 hours (for example). Plotting 20,000 points on multiple graphs can cause long delays. Changing font type can also change the font size due to font size limitations. To restore default fonts, select the Default button from the font settings window and restart the program. Approximately once a month, the moon does not rise (or set) on a given day. The chart will be empty if (1) the database is empty (example, when the program is first started, or (2) Data has not been collected in the plot time frame specified in the attributes window (the program was turned off). This problem is generally a result of bad sensor data from your station, but can be repaired in your database. The data shown in graphs is stored in the database. To fix this data, go to Settings Database Settings and edit the database. This problem is generally a result of bad sensor data from your station, but can be repaired in your archive memory. The data shown in the NOAA reports is stored in the archive memory. To fix this data, go to Settings Daily Archive, Settings Monthly Archive or Settings Yearly Archive and edit the data. Virtual Weather Station launches Notepad to view text files. This is a problem with Notepad. Use another text editor such as Microsoft Word or Wordpad to view the data. Virtual Weather Station prefers high resolution or 16-bit colour. Some images may result in poor quality at lower resolution settings. The software attempts to put a numerical marker at even increments, but this is not always possible. To improve your numerical marker increments, select a high and low range value that results in a difference of a multiple of 10. For example, a low of -40 and a high of 60 will provide a difference of 100. This will produce better marker increments then a low of -20 and a high of 100.

PROBLEM The Dew Point of the weather station is reporting "LL" or limited to 0C (32F) and Virtual Weather Station is reporting a value The sea-level barometer does not report what is entered in the Station Settings window. The software is reporting a cloud base when there are no clouds in sight. A Virtual Weather Station parameter displays a different number than the station console The Daily Rain is not correct The monthly rainfall reported in the NOAA report does not agree with the sum of the daily rainfall. How do I change my NOAA report data? When I update one of the fields in the daily summary data, this change is not updated in the monthly or yearly summary data. The Alarm Sound will not play Some of the check boxes on the Parameters Display Panel are dimmed The displays do not retain their position when exiting the program.
SOLUTION The Oregon Scientific unit does not report dew points below 0C (32F) but Virtual Weather Station continues to report these values.
Virtual Weather Station only reports the sea-level barometer from your station. This is only an estimate based on relative humidity and temperature. Other weather parameters affect the cloud base, and should only be used as an estimate. Make sure that you have not entered a calibration. Changing the calibration of a sensor will not change the value on the display. The program must be running at midnight for today's daily rainfall to be correct. The Weather Station does not store daily rainfall. This is due to the station total rainfall reset by the user, or the values for minimum or maximum rain edited by the user. This is done in the Archive Settings window, and not the database. You must edit each of these data fields. For example, if the minimum temperature on January 9, 2000 is changed, and it is the minimum for the month and year, you must change this field in the monthly summary panel and the yearly summary panel. This feature requires a sound card. This is not a problem with VWS, but with your sound card. Contact your sound card manufacturer Not all parameters can be displayed with all of the weather elements. For example, graphs require historical data, and it does not make sense to plot sunrise. Make sure you have enough memory in your computer to save the displays. The display positions are saved in the file VWS\setup\position.bin. If this file is corrupted, close VWS, delete this file and restart Virtual Weather Station. You will need to reset the displays again. Try a different drive. The drive you installed Virtual Weather Station on may be read only. This is a Windows problem. Minimize and maximize the application again to refresh.

After hiding Virtual Weather Station with the taskbar icon, and recalling the display by double clicking on the taskbar, the window does not refresh One of the sensors is not updating, and VWS will not begin executing. My system clock is losing time when I run Virtual Weather Station.
Virtual Weather Station requires all of your sensors to operate to properly obtain data. If one sensor is not functioning due to batteries or interference, deselect this sensor. Use the Synchronization feature in Virtual Weather Station. Select Settings Synchronize Date and Time from the menu bar. NOTE You must be the administrator on a Windows NT or above machine for this to work. You may have a bad ROM BIOS chip or your computer motherboard may need a new battery. Power management software in Windows can also cause clock time loss. When you connect your weather station to the communication port, Windows must process interrupts to read this data. With weather stations, this occurs every 3 seconds. This causes the clock to slow down. If your computer is running other utilities such as an antivirus program, the clock speed may be affected even more. Virtual Weather Station provides limited foreign language support. To change the titles to the language of choice, edit each individual display. Channels 1, 2 and 3 are designated channels for the optional sensors. Increase the CPU usage during FTP operation by selecting Internet FTP General Settings Max CPU During FTP Virtual Weather Station accesses some applications through the command line. This is because WINOLDAP is not being automatically
The language does not change when changed from English What are channels 1, 2 and 3? I commonly receive timeouts during FTP Why does "WINOLDAP" run multiple times and not shutdown?

SOLUTION closed when it finishes. In order to remedy this you need to modify the DOS box properties for CONAGENT.EXE, CONAGENT.PIF, or _DEFAULT.PIF (probably in \windows). 1. Start Explorer. 2. Locate one of the above files in the \windows\system directory. 3. When over the file click the right mouse button. 4. Choose 'Properties' from the speed menu. 5. Choose the 'Program' tab. 6. Turn on the 'Close on exit' option. There may be wind run calculation problems with specific computers due to the microprocessor and other hardware devices. If you find the wind run values are out of range, place the following line in your win.ini file: wuseDefaultTimer=True. To reset these values, select Settings Recall Daily, Monthly and Yearly and edit the wind run for the day, month and year. Some stations only report the sea-level barometric pressure after adjusted from the console. To back-out this correction, set a negative bias in the calibration panel.
