STEP 10: TREND LOGGING & PRINTING

Prism 2 Technical Guide

To print a log, ﬁ rst select a printer from the Default Printer Selection

Dialog Box located at the bottom right of the Trend Logs Screen

and then click < Print>. Every time you open Prism 2, this printer

selection will be the default printer until you change it.

NOTE: If you select a printer from this list box, it will become

the default printer for all programs on your computer unless

you select a different printer in Prism 2 or from the Windows

Control Panel.

To graph data from a log, click < Graph>. The Log Selection

Window will appear again. Select a highlighted date to graph. The

Trendlog Graph Screen will ﬁ ll up your entire computer display.

Click <Exit> to return to the Trend Log Screen.

NOTE: Some controllers don’t have the ability to create line

charts of the logged data. If this is the case, Prism 2 will display

one or more message boxes informing you that it cannot display

line graphs.

Below is a sample line graph display from a Variable Air Volume

Box Controller.

If you would like to export a day’s worth or month’s worth of

log data for further analysis not provided in Prism 2, select either

< Export Daily> or < Export Monthly>. Prism 2 will create a

comma delimited . CSV ﬁ le that can be opened in most spreadsheet

and database applications.

If you select <Export Daily>, the process is done automatically.

Prism 2 will display the ﬁ le name and location created for the

exported data.

If you select <Export Monthly>, the following dialog box will

appear:

Select a month from the Selected Month drop down box, select

a year from the Selected Year scroll box, and then click < Begin

Processing>. When the processing is done, the message DONE

will appear in the bottom status bar of the window. Your data will

be saved in your Prism 2 directory within a new subfolder titled

Export.
