Front Panel Operation 21
3.3.3 Local Sense
By default, the power supply is set up for local sense. See the gure 3.2 for the Remote and Local Sense setup.
Figure 3.2 Local Sense
When local sense is selected, the positive lead (+) of the DC output is connected to the positive end (+) of the load
and the negative lead (-) of the DC output is connected to the negative end (-) of the load.
When this sensing mode is selected the wires connecting between DC outputs to the load must be as short as possible.
The local sense is the default conguration.
DO NOT disconnect the wires if remote sense is not used. Doing so will cause erratic behavior and may
damage the power supply under certain conditions.
Never connect any power source into any of the four terminals at any time during operation. When output
is enabled, DO NOT use your hands to touch the terminals or the screws that are designed to tighten wires
to the terminals. Doing so may create a shock hazard under high voltage output conditions.
Remote Sense
When remote sense is selected, the positive sense (+S) and positive lead (+) of the DC output are connected to the
positive end (+) of the load, whereas negative sense (-S) and negative lead (-) of the DC output are connected to the
negative end (-) of the load. To enable remote sense, follow the steps below:
1. Power OFF the supply and disconnect all loads and cables connected to it.
2. Use a small at blade screwdriver connect the S+ to the DUT’s positive (+) terminal, and connect the S- to the
DUT’s negative (-) terminal.
3. Do not connect any wires to Vo+ and Vo- terminals.
4. Power ON the power supply, and then congure and enable the output. The setup should look like the gure above.
