8. Graph Overview

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

timestamped 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. Overview

a. The recorded power quality events graph displays the time-stamped

power quality events (up to 60) recorded and stored in the MULTIPAK’s

internal memory. The events are plotted as individual data points.

b. While the events are timestamped in the MULTIPAK’s 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.

c. All events recorded while a computer is connected to the MULTIPAK will

have an accurate date and time stamp, since the computer will supply
