ION7550 / ION7650 User GuideChapter 3 - Front PanelTrend Bar Graph DisplaysBar graph displays can show up to four real‐time (numeric) parameters along withtheir upper and lower extremes.Each bar graph automatically scales its output based on the magnitude of itsextremes. The real‐time value of each bar graph is displayed to the right of thegraph.NOTEScaling is applied separately to each bar graph in the display. Do not compare the magnitudes of twovalues based on the size of their bars.Trend DisplaysThe Trend Display screen graphs the historical data of up to four differentparameters simultaneously. A movable cursor, consisting of the intersection of avertical line and a horizontal line, displays the value and timestamp of any plotteddata within a parameter. The cursor displays the values of one parameter at onetime only. Use the Up and Down navigation keys to move from one parameter toanother.In addition, a Trend Display log screen displays data logs for any graphedparameter – up to 3360 logs for each parameter. That is equivalent to 35 days worthof 15 minute data. The graph is updated when a new set of values is recorded. Thehighest supported update speed is once per second.The front panel displays three preconfigured trending screens: V‐Trend (voltage),I‐Trend (current), and P‐Trend (power).Default Front Panel Display ScreensThe meter is factory configured to display a number of data screens on its frontpanel:40 display screens for all ION7550 meters and ION7650 meters withoutEN5016049 display screens for ION7650 meters with the EN50160 ordering optionEach screen is accessible with a corresponding Softkey.
