Max Delta R%
Max Delta R% identifies the maximum resistance difference percentage between all three test
leads. This imbalance as it is commonly known is collected during each test conducted on the
motor. The results are plotted in this graph with the test date and time shown in the X axis.

Resistance Trending Graphs
There are three different types of resistance data that can be trended: balance, line-to-line,
and coil. Selecting one will bring up a graph similar to the one shown in the example.
Resistance measurements are taken against time and show very little variation over the test
interval.
Each of the three leads is shown in its own color. Each data point is indicated by a square,
diamond, or triangle marker. Hovering over a data point will show a date/time stamp and
give the value of the test. This feature allows for easy identification of the test record for that
point.
