5 - Viewing Test Data
42
ñ the number of failures for individual harmonics in the test to-date, as well as the number of
failures for individual harmonics in the 2.5 minute window criteria.
ñ the failure count that exceeds 50%, 75% , 90%, and 95% of the regulation’s limits.
Failures are indicated in red and are enclosed in parentheses. When the data is sent to a printer, failures
are enclosed in parentheses. Color printers will also print errors in red.
Search Parameters
When the display is set to Fixed, you can perform search functions on specific test data. Search options
let you:
ñ Search for specific items such as:
single failures
2.5 minute failures (only applies to fluctuating harmonics)
all failures (only applies to fluctuating harmonics)
harmonic magnitudes > than the specified value (specify AMPS or % of Spec. in the Edit
Graphs dialog box)
ñ specify Harmonic Selection criteria for the following harmonics:
Odd harmonics
Even harmonics
Odd
≤
19 harmonics
All harmonics
Nth harmonic (specify a harmonic number)
Time-Series Display
The Time-series display is used to view quasi-stationary or fluctuating harmonic data of a specific
harmonic. Depending on the selected zoom factor, each bar may represent a single data point, or multiple
data points. For example, if the zoom factor is 1:10 (shown as 10 in the zoom field), each bar represents
10 data points.
Note To edit the graph, click with the right mouse button on any area of the graph. This puts
up the Edit Graph Attributes dialog box, which lets you configure items such as the
graph axes, the zoom factor, and lets you select a specific harmonic to review. Refer to
“Editing the Graph Attributes” later in this chapter for details.
