2.3. Operating the Electronic Load

The SDL1020X-E offers various operating modes for different testing scenarios:

• Constant Current (CC) Mode: Maintains a constant current draw from the DUT. Use the front panel controls to set the desired current value.
• Vol. Constanttage (CV) Mode: Manté un volum constanttage across the DUT. Set the target voltage using the controls.
• Constant Resistance (CR) Mode: Simulates a constant resistance load. The current drawn will vary with the voltage.
• Constant Power (CP) Mode: Maintains a constant power dissipation. The current and voltage will adjust to keep the power constant.
• Mode dinàmic: Allows for rapid switching between two load levels (A/B) in CC, CV, CR, or CP modes. Configure the levels, dwell times, and rise/fall times.
• Mode de llista: Program a sequence of up to 100 steps with different load parameters and durations. This is ideal for automated testing and characterization.

Refer to the comprehensive user manual for detailed instructions on configuring each mode, setting parameters, and interpreting measurement results.

2.4. Manteniment

To ensure the longevity and accuracy of your SDL1020X-E:

• Neteja: Feu servir un drap suau i sec per netejar l'exterior. No utilitzeu productes de neteja abrasius ni dissolvents.
• Ventilació: Ensure adequate airflow around the device. Do not block the ventilation openings.
• Emmagatzematge: Guardeu el dispositiu en un entorn net i sec quan no l'utilitzeu.
