2 Element Delta (Aron/Blondel)
Example: Blondel or Aron connection, simplifies the
connection by the use of only two current sensors.

Load Study (no voltage measurement)
Note
Make sure that the current arrow on the sensor is
directed towards the load to provide positive power
values. The current sensor direction can be corrected
digitally in the Connection Verification screen.
Nominal Voltage: Load Studies Only
Select a nominal voltage from the list. If a voltage is not
shown in the list, a custom voltage can be entered. Set the
nominal voltage to off if the apparent power readings are
not required.
Current Range
Configure the current range of the attached sensor. Three
ranges are available:
• Auto
• Low Range
• High Range
When set to Auto, the current range is set automatically
and depends on the measured current.
Low Range is 1/10 of the nominal range of the attached
current sensor. For example, the low range of an
iFlex1500-12 is 150 A.
High Range is the nominal range of the attached current
sensor. For example 1500 A on an iFlex 1500-12.
Note
Set the current range to Auto when you are not
sure about the maximum current during the
logging session. A specific application can require
you to set the current range to a fixed range rather
than Auto. This can occur because the Auto range
is not gap-less and may lose too much information
in the case of a highly fluctuating current.
