  • Verify that the load is correctly connected to the output terminals.
  • Assicurarsi che il volume impostatotage and current values are not zero.
• Letture errate:
  • Ensure proper connection of test leads to the load.
  • Compare readings with a calibrated multimeter to verify accuracy. If significant discrepancies exist, contact support.
• Memory Settings Not Saving (M1-M6):
  • Ensure you are pressing and holding the memory key for approximately 3 seconds to save. A brief press will recall.
  • If issues persist, try a factory reset (refer to manual for specific procedure, if available, or contact support).

9. Informazioni sulla sicurezza

Observe the following safety precautions to prevent electric shock, injury, or damage to the unit:

• Collegare sempre l'alimentatore a una presa dotata di messa a terra.
• Non utilizzare l'unità in ambienti umidi oamp condizioni.
• Non aprire il casing of the power supply. There are no user-serviceable parts inside, and doing so voids the warranty and poses a risk of electric shock.
• Garantire un'adeguata ventilazione intorno all'unità per evitare il surriscaldamento.
• Non superare il volume massimotage and current ratings of the power supply or the connected load.
• Utilize the Over Voltage Protection (OVP) and Over Current Protection (OCP) features to safeguard your circuits.
• Disconnect the power supply from the mains before performing any maintenance or connecting/disconnecting loads.
• Tenere i bambini lontani dal dispositivo.
