4.7 Graph Overview & Control
a. Graph Control
i. The graphs used to display the recorded power quality events (normal mode) and line voltage
(Enhanced Logging Mode) contain Zoom, Cross Hair, and Drag functions that are useful when
analyzing data:
Legend: Press the L icon to display the Graph Legend to show the values of the Time
Stamped data. Pressing the icon again toggles the legend off.
Zoom: Press the magnifying glass icon to enable Zoom mode. Pressing the icon again
stops Zoom mode, and restores the graph to its full display scale.
Cross Hair: Turns the cross hair on and off.
Drag: Enables/Disables Drag mode. When in Drag mode, press and hold the left mouse
button somewhere on the graph, and move the mouse. The graph will be dragged in the
corresponding direction.
ii. Several control buttons are available below the graphs, depending on which mode is active:
1. G1/G2: Toggles between Graph 1 (recorded power quality events) and Graph 2 (line
voltage). Available after entering Enhanced Logging Mode.
2. **/--: Toggles the data display of Graph 2 (line voltage) between linear and discrete data
points. Available when Graph 2 is visible.
3. Stop: Stops Enhanced Logging Mode. Available after entering Enhanced Logging Mode.
b. Graph Data
i. Power Quality Events Graph
1. The recorded power quality events graph displays the time-stamped power quality events
(up to 60) recorded and stored in the Surge + Diagnostic internal memory. The events are
plotted as individual data points.
2. While the events are time-stamped in the Surge + Diagnostic internal memory by the
elapsed time since the previous recorded event, they are plotted on the graph with an
estimated date and time, based on the connected computer’s Windows system time. The
duration of a power outage is not recorded, so the date and time of events prior to and
including the most recent power outage may not be accurate. Events with an accurate
estimated date and time are plotted with a red circle; events with a possibly inaccurate
date and time are plotted with a black circle; the time the computer was connected is
plotted with a blue square.
