Make rain data corrections

You can set the correct totals under control panel, barometer offset, other offset and initial

rain totals. You can also set other months rain totals under view, rain in detail, but that

does not change the rain totals in the log file (the log file also affects the totals under view,

averages/extremes/noaa 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 7 days. When

setting/resetting there, the changes only apply to that data on that screen. To correct rain

totals under view, averages/extremes you need to 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 that 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 month102005.inf for October 2005), and then click

Convert. Wait for the Finished alert.

Graphs show spikes and when the mouse rolls over the

spikes, abnormal readings appear

This appears most often with the dew point or windchill graph lines. The problem is

display-only issue due to an out of range graphing error. The actual data is not affected.

The solution is to extend the graphing range. Either use the lift/lower buttons in the Setup,

Graph Setup, or in the Graph Setup, change the graph ranges to prevent the spikes.

COM port error

This often results because another software application is using the same COM port.

Possible conflicting devices include PDA synchronization applications or bluetooth cell

phone synchronization programs, etc.

Make sure no other software is accessing the COM port, especially other weather station

software applications (for example, Heavy Weather with La Crosse weather stations). Also

note that Microsoft Windows can swap COM port numbers.

If you are unable to resolve the COM port failure, you might be able to use a USB to serial

adaptor, or a serial port PCI card. Windows Device Manager will identify the assigned COM

ports. To access Windows Device Manager, do the following:

1. €Click Start, and then click Control Panel.

1. €Double-click System.

1. €On the Hardware tab, click Device Manager.
