2.2 Current Transducers
The load current is measured in galvanic isolation by the current transducers.
Internally, the entire current range is mapped to a voltage range of 0..10 V.
2.2.1 Configuring the Current Transducers
The range of currents to be measured is configured using solder straps (on the
solder side of the ES4455.1 Load Board) at the current transducers (see Fig. 2-1
on page 11).

Right)
Note
Use only the two inner rows for the solder straps as the voltage converter is
soldered to the outer ones.
Note
Please note that changing the current ranges makes recalibration necessary
(see "Calibration" on page 15)!
