WD Rainfall FAQ

Rainfall

Why don't Weather Display rain totals match my weather station?

Weather Display saves rain totals separate from the weather station, which makes it more flexible for rain reset times, rain reset month, etc. You can enter values in Control Panel, Offsets & Initial Rain.

To set the starting values, do the following:

1. Click Control Panel.
2. Click Offsets & Initial Rain.
3. On the Temp./Baro Offsets/Rain Totals tab, enter the amount in the text box to the right of Set. Enter the values in millimetres (mm) or inches if you've selected the Inches check box. For example, enter 55.5 for mm, or 2.5 for inches. An alternative is to select the value from the slider (click and it shows the equivalent in inches).
4. Click Set and then click Yes to save the values.

How do I correct monthly and yearly rain totals?

1. Click Control Panel, and in the Station Settings section, click Offsets & Initial Rain.
2. Enter rain offsets. Remember to click Yes to save the settings.

You can also set other month's rain totals under View, Rain in detail, but that doesn't change the rain totals in the log file (the log file also affects the totals under View, Averages/Extremes Noaa Style Reports), it just sets the totals for the monthly rain graphs in the Rain in detail screen (and same applies for rain for each day of the last seven days. When setting/resetting there, the changes only apply to that data on that screen. To correct rain totals shown in View, Averages/Extremes Noaa Style Reports you must change the last rain total for the day (i.e. the last entry just before the daily rain total is reset) in the log file for the appropriate month.

If you have lost your rain totals, then you should be able to find the last good rain total in the log file.

Note: You can restore the log file for a month if it is bad, but the graph data is still available for that month (under Graph history), by using the action Convert log files to graphs, but select Convert graph files to log files, and then make sure the correct graph data file is selected (for example month102018.inf for October 2018), and then click Convert. Wait for the Finished alert.

How do I specify custom rain years (for example July through June)?

1. Click Control Panel, and in the Station Settings section, click Units and Other Settings.
2. On the Reset Times tab, enter the Month to reset the yearly rain total.
