Use local sense:
Local sense doesn’t compensate the voltage drop on the connection wire, the
operation is:

between + and S+, - and S-.
2. Connect the positive and negative terminals of the front panel to the device
under test.
Use remote sense:
Remote sense compensate the voltage drop on the connection wire, the
operation is:
1. Disconnect the wires/short clips between + and S+, - and S-.
2. Connect wires from S+, S- to the device under test.
3. Connect wires from +, - to the device under test.
NOTE
In order to ensure the stability of the system, using armored twisted pair cable between
the remote sense terminal of IT6900 and load.
Please note that the positive and negative polarity when wiring, otherwise it will damage
the instrument!
