5. Mode d'emploi

5.1 Réglage du volumetage et courant

1. Ensure the output is OFF before setting parameters.
2. Réglage du volumetage: Press the 'V' button (or the corresponding button to select voltage adjustment). The voltage display will flash. Rotate the adjustment knob to set the desired voltage. Press the 'V' button again to confirm or wait a few seconds for it to auto-confirm.
3. Courant de réglage : Press the 'A' button (or the corresponding button to select current adjustment). The current display will flash. Rotate the adjustment knob to set the desired current limit. Press the 'A' button again to confirm or wait a few seconds for it to auto-confirm.
4. Activation de la sortie : Une fois voltage and current limits are set, press the Output ON/OFF button to enable the power output. The button will illuminate, and the display will show the actual output voltage et actuel.

5.2 Fonctions de mémoire (M1-M6)

The device allows you to store and recall up to 6 sets of frequently used voltage et paramètres actuels.
