Remote measurement
In the mode of CC, CV, CR, CW, when a relatively large current flows through
the electronic load, a relatively large voltage drop will be generated on the
connection line between the instrument under test and the load terminal. In
order to ensure the measurement accuracy, the electronic load provides a
remote measurement terminal on the rear panel, and the user can use this
terminal to measure the output terminal voltage of the instrument under test.
SENSE (+) and SENSE (–) are the remote sensing inputs. Before using the
remote measurement function, you must first set the load to remote
measurement mode. The steps are as follows:

(Optional) Unlock the load input terminal cover.
Unscrew the screws of the input terminals. Connect the red and black test
cables to the input terminals. Re-tighten the screws.
When maximum current that one test cable can withstand fails to meet the
current rated current, use several pieces of red and black test cables. For
example, the maximum current is 1,200A, then 4 pieces of 360A red and
black cables are required.
(Optional) Install the load input terminal cover.
Directly connect the other end of the red and black cables to the DUT
terminal.
Press (Shift)+
Press to select SENSE, press
Select ON, open SENSE function, then the load is set to remote
measurement mode.
Note:
When not using the remote measurement function, press the OFF key to
close the remote measurement mode.
When using the IT-E164 to connect the DUT (quick charge device), turn on
the Sense function and the Sense terminal on the rear panel is not
connected, which will cause the instrument to report Sense reverse
connection protection (RRV).
Refer the following diagram to connect test cables.
