Inspection and Installation

Schematic Diagram of S+/S- and +/- Rear Panel:

When the DUT consumes high current, voltage drop will appear at the

connecting wire between the power supply and the DUT terminals. To ensure

measurement accuracy, a remote measurement terminal is provided at the rear

panel of the power supply, from which, the User may measure the input

terminal voltage of the DUT.

Dual-channel power supply Single-channel power supply

⚫ S+/S-: Remote measurement terminal: when remote measurement

function is applied, lead out the “S+ and S-” for connecting the DUT.

⚫ +/-: Output terminal.

Use local measurement:

The local measurement does not compensate the voltage drop on the wires.

The operations are as follows:

1. Use the shorting clip on the rear panel or directly install wires between +

and S+ as well as - and S-.

2. Connect the output of positive and negative terminals on the front panel or

the + and - terminals on the rear panel to the DUT through wires.

Wiring Schematic Diagram of Local Measurement is as follows:

Use remote measurement:

The remote measurement function allows compensation for voltage drop of the

electric wires between the power supply output terminal and the DUT.

Operations are as follows:

1. Remove any wire jumpers or shorting clips between the + and S+ as well

as between the - and S- of the terminal board connector on the rear panel.
