Frequently Asked Questions

Q. How do I view data for a specific date range?
A. The first screen you see when clicking on Basic Device Info, Events and Data Log gives you the following options: viewing the last 20 rows (this is the fastest way to view the information), or viewing information from the last day or from the last week. You can also view data for a specific date range, click on the button next to “Start Date“ and “End Date“. A calendar window will open in which you can specify the dates. When you click on “Show for date range” below the table, it will refresh with the data for those dates.
 
Q. I want to view information for a wide date range, but I want the information to show up faster.
A. The best way to do this is to select a small date range starting at the date you are interested in. then use the next button to continue viewing additional records.
 
Q. How can I choose the amount of tabular data I can see on one page?
A. The default number of rows is 20, but you can change that number in the box between the Next and Previous buttons.
 
Q. Can I see the details of a specific measurement in the Basic Device Info screen?
A. In order to view details of a specific reading, click on the date/time of the record you want to view. A details screen will open.
 
*Q. When I want to view a graph I get a security warning. What do I do?
A. This warning asks you if want to install the “……/CabFiles/……” file. Click on “yes” to enable viewing of graphs.
 
Q. Can I see a trend for a specific measurement?
A. In the Basic Device Info screen, click on the title for that measurement. A trend graph will appear.
 
Q. How can I create custom trends?
A. From the Trends menu select “Create Trends”, choose up to 3 parameters to plot in one graph for up to 4 graphs at a time. One of the 3 parameters can be associated with the right axis by checking the checkbox to its right. You can choose a 2 Dimensional or 3 Dimensional graph and whether or not to include lines representing the minimum, maximum, and average points for each parameter and whether or not to include gridlines in the graph.  You can also optionally choose a background color for the graph, a title and a date range for the data to be plotted. Click on “Create Graph” to view the graph. (This graph is not saved after viewing).
 
Q. How do I zoom?
A. Once the graphs are displayed, you can zoom in to a part of the graph by holding down the mouse in the top left corner of that part and dragging it towards the bottom right corner. In order to return the graph to its original state, hold down the mouse and drag in the reverse direction. 
 
Q. Can I see additional points in a graph?
A. You can scroll vertically and horizontally. To scroll across, press the left mouse button and, maintaining the mouse button pressed, drag the mouse in the desired direction. When you release the mouse button the graph will remain at the new location.  Currently, there are only 2 pages of data for the trends and 1 for the waveforms.  In the future, you will be able to get more data from this screen on demand
 
Q. What if I want to see only individual parameters at one time?
A. You can turn off any of the parameters on the graph by unchecking the check box next to the name of that parameter.
 
Q. What does it mean  to ‘Turn Point Labels Mode On/Off’?
A. When the box is checked, you can click on any point on the graph and a label will be displayed with its value.  These labels will also be included when printing the graph.  When the box is unchecked, the labels will be removed.
 
Q. How can I view Waveforms?
A. Harmonics and Disturbance waveforms are displayed in graph form. The default is the most recent one of each; you can choose from a list of all waveforms recorded for this device. 
 
Q. Which data logs can I view?
A. View Data Log shows the first active Data Log for the current device. You can choose a different active Data Log to view by selecting from the list at the top of the screen.
 
Q. How do I change from one device to another?
A. At any point, you can change the current device by clicking on the Change Device  menu or from most of the screens the ‘Click here to change devices’ button and again choosing the site and device.
 
Q. What does Load Profile show me?
A. Load By Day – shows the energy readings for each day of the current month by default, calculating the power factor and totals. A bar graph of the values is opened up in another window. You can change the month and year from either the graph window or the main table window.
Load By Month
– shows the energy readings for each month of the current year by default, calculating the power factor and totals. You can change the year from either the graph or the main table.
 
Q. Is there a way for me to see all the information that was logged when an event was triggered?
A. Yes. For any event that has a link on its date and time, more information can be provided about it. By clicking on the link you will view a page that contains all data logs and waveforms for that event.
 
Q. What does a red energy value in the Load By Day table mean?
A. As noted next to the red ‘*’ at the bottom of the page, it means that the energy was reset either manually or automatically and therefore the value is approximate.
