Status screen Notes
The default screen after clicking the “See Charts” button shows the archived data for each channel. It may take 30
seconds or so to load the data and display the channels. After initial loading the samples will be displayed as
taken.
NOTE: If you just started the SITEGUARD and no data has been sampled, you will have to wait for the archive
sample period to pass before seeing the first data point. Archive data always grows from the right. The internal
Real Time Clock must be set properly before archive data will appear. Archive data can be downloaded as a CSV
file (each channel) by right-clicking the disc symbol. Left click will show the data on screen.
Clicking the “Goto Live” button for each channel will show data samples at the fastest rate, approximately 0.5
second, and the live data always grows from the left, with the chart data shifting left when the chart is filled.
Each channel can be expanded or contracted vertically for better viewing by clicking the symbol.
SITEGUARD MAINTENANCE
Battery
The battery (CR2032) on the SITEGUARD board is used to back up the real time clock for logging purposes. Logged
in users can see the current system time on the Device Setup page under Date and Time settings.
If logging is enabled, download and save the data periodically, then clear the log files. If you just let it run, you will
end up with Gigabytes of data broken up into 5 MB files that must be downloaded individually and this will take a
very long time.
You can also remove the card and work with it on the PC using a card reader. Replace the card when finished.
