SYSTEM STATUS - Trending - Trending Setup
DESCRIPTION: This is the Trending Setup screen. Up to eight
channels can be monitored in real time trending, and up to
eight channels monitored in history trending.
Real Time Trending - is a method by which the user can set
the Quantum™ LX to map analog inputs to a graphic chart for-
mat. These analog input values are stored at a specic interval
over a corresponding period of time. The graphed values will
scroll across the screen from left to right, at a speed that is de-
termined by the recording interval. Two individual data points
can be viewed on the Real Time Data Log screen. A total of
900 values are stored. Trending data is lost upon power cycle.
The following setpoints are provided:
Real Time Recording Interval – The time interval that
denes how often the real time trending data values are
updated. This value may be set for any time duration be-
tween 1.0 second and 86,400.0 seconds (24 hours).
History Trending - is a method by which the user can set
the Quantum™ LX to record analog inputs to a graphic
chart format. This feature is similar to Real Time trending,
except that the data is not lost at power cycle. The events
that occur will scroll across the screen, at a speed that
is determined by the recording interval. A total of 2000
values are stored.
History Recording Interval – The time interval that de-
nes how often the history trending data values are up-
dated. This value may be set for any time duration be-
tween 1.0 minute and 60.0 minutes (1 hour).
To program this screen with the data you wish to trend, high-
light the Enable Real Time Trend Channel 1 (or whatever chan-
nel you wish to use), by using the tab key. Once the box has
been selected, a drop down menu will appear for that channel.
On the right hand side of the drop down box will be an arrow.

ates a download of the Real Time and History data les.
These les can then be imported into a database such as

ible device into the USB port of the Quantum™ LX. This
device can be a USB cable that is connected directly to a
personal computer, or a USB Flash Drive. When monitor-
ing remotely using a personal computer, and this button is

showing two les:

ber of the Quantum™ LX. When the les appear in the screen
window, simply right click on either le, and select from the
menu “Save Target As…”, and save the les to a convenient
location. By using Windows Explorer™, you can then double
click on the le, and it will automatically open the le in Mi-
