2. Informazioni sulla sicurezza

WARNING: Always adhere to safety precautions to prevent electric shock or damage to the instrument.

  • Non toccare le sonde direttamente con le mani per evitare scosse elettriche e garantire la sicurezza personale durante il test.
  • Prima dell'uso, ispezionare le sonde di prova per accertarsi che non vi siano danni all'isolamento o parti metalliche esposte.
  • Non utilizzare la corrente e il voltage intervalli in modo intercambiabile per evitare danni allo strumento.
  • Se non si conosce l'entità del voltage o corrente da misurare, iniziare con l'intervallo più alto e quindi selezionare l'intervallo appropriato in base al valore misurato.
  • Prima di collegarlo a un circuito, assicurarsi che il multimetro sia impostato sulla funzione e sull'intervallo corretti.
  • Non misurare mai il voltage on a circuit with the multimeter set to resistance, continuity, or diode mode.
  • Do not exceed the maximum input values specified in the specifications.
