About Reports
Vaisala devices 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
devices, refer to your vLog product guide. To set the sample
interval for 300 Series Transmitters refer to the specific
Vaisala product guide. Also see “Editing Device Properties
and Aliases” on page 45.
With viewLinc you can monitor real-time conditions for
devices over the network, analyze or graph changes in
conditions over time, or compare conditions recorded by
different devices. This analysis is performed using the
Reports function.
Historical data from a Vaisala Veriteq device can also be
transferred to a local directory on a set schedule - be it daily
or weekly - using viewLinc’s Transfers tab. Once transferred,
data can be retrieved for exporting (into .tsv) and printing,
depending on your reporting needs. See Chapter 9:
Transfers
for more.
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).
• Historical data reports provide a detailed history of
location values (presented in both graphical and tabular
form).
