the current, the amount of error will be large if the
frequency is low. Because of this, always use a CT with
as large a capacity as possible. See the following chart
and Figure 7-2 for recommended measurement devices.
MEASUREMENT POINTS AND METERS
Since the Drive's input/output voltage and current
contain high frequencies, selection of the wrong measur-
ing device can lead to gross miscalculations. When
using a CT (current-detection transformer) to measure
