Initially, as each channel appears, its scale appears at the leftedge of the display (as shown below), but in order to show the maximum amount of trend data, the scale isoverwritten after a few seconds.By default, after a few seconds, the‘chart’ expands leftwards to hidethe scale. This feature can be disabledin the Instrument.Display areaof configuration (Section 4.1.3,H.Trend scaling) so that the scale ispermanently on display.Channel 1 6.23VInst nameFigure 3.4.2 Horizontal trend display modeNote: Timestamps appear to the right of the gridline to which they relateUse of the up arrow button causes the next enabled display mode to be entered (default = vertical bargraph).Use of the page key calls the top level menu.3.4.3 Vertical Bargraph modeThis display mode shows the channel values as a histogram. Absolute alarm threshold values appear as linesacross the bars, grey if the alarm is not triggered; red if the alarm is triggered. Alarm symbols appear foractive alarms.Bargraph widths for four to six channels divide the width of the display screen equally between them. Forone and two channels, the width is fixed, and the bars are centred on the screen.
