Specifying 2-Wire or 4-Wire Sense
When 4w mode is selected, ensure the load is connected to the rear panel output for accurate reading.
DO NOT USE both front and rear panel output concurrently. This may lead to inaccurate output reading.
You have the option to use the remote sense terminals on the rear panel to measure the voltage at the device under
test (DUT).

The 2w mode closes a relay within the power supply to short the output and sense connectors. This means that only
two wires are used, and 4-wire sense is disabled. The 4w mode opens the relay in order to separate the output and
4-wire sense inputs. By default, 2w is selected.
