About Historical Data
Vaisala data loggers have the ability to store large amounts
of data inside them. Data is logged in frequencies from once
every 10 seconds to once every 24 hours. To set this
frequency -- known as the sample interval -- for Vaisala
Veriteq loggers, refer to the Spectrum or vLog User Guide. To
set the sample interval for 300 Series Transmitters refer to
the specific Vaisala product User Guide .
With viewLinc you can monitor real-time conditions for
loggers over the network, analyze or graph changes in
conditions over time, or compare conditions recorded by
different loggers. This analysis is performed using the
Reports tab.
Generating Historical Data Reports
viewLinc provides you with a set of graphical reports which
can help you easily view trends in data readings or alarm
monitoring statistics (such as alarm trigger frequency).
•
Alarm reports provide an overview of alarm events over a
period of time (events related to every alarm are grouped
together and presented in a readable form).
•
Channel History reports provide a detailed history of
channel values (presented in both graphical and tabular
form).
