2.2 භෞතික සම්බන්ධතා

Before powering on the device, ensure all necessary connections are made securely.

1. බල සම්බන්ධතාවය: Connect the supplied power cord to the AC power input on the rear panel and to a suitable AC power outlet. Ensure the voltage selector (if present) matches your local power supply.
2. Load Input Terminals: Connect the device under test (DUT) to the red (+) and black (-) input terminals on the front panel. For high current applications, use appropriate gauge wires to minimize voltagඊ වැටීම.
3. Sense Terminals (Optional): For precise voltage regulation at the DUT, connect the sense terminals (S+ and S-) to the DUT's output. This compensates for voltage drop across the load wires.
