2. Informazioni sulla sicurezza

Per prevenire scosse elettriche o lesioni personali e per evitare danni all'oscilloscopio o alle apparecchiature collegate, osservare le seguenti precauzioni di sicurezza:

• Messa a terra corretta: Ensure the oscilloscope is properly grounded. The instrument is grounded through the power cord's grounding conductor. To avoid electric shock, the grounding conductor must be connected to earth ground.
• Connettersi e disconnettersi correttamente: Connect the probe output to the oscilloscope input before connecting the probe to the circuit under test. Disconnect the probe from the circuit under test before disconnecting it from the oscilloscope.
• Rispettare tutte le classificazioni dei terminali: To prevent fire or shock hazard, observe all ratings and markings on the instrument. Consult the product manual for more information about ratings before making connections to the instrument.
• Use Proper Probes: Use only probes supplied with the instrument or recommended by the manufacturer. Ensure probes are rated for the voltage and current being measured. The included P4250 High Voltage Probe has a 100:1 attenuation ratio and is rated for 2KV Working Voltage (Vp-p).
• Evitare circuiti esposti: Non toccare i collegamenti o i componenti esposti quando l'alimentazione è presente.
• Non operare in caso di guasti sospetti: If you suspect damage to the instrument, have it inspected by qualified service personnel.
• Mantenere condizioni asciutte: Non utilizzare lo strumento in ambienti umidi oamp condizioni.
• Operare in un'area ben ventilata: Garantire una ventilazione adeguata per evitare il surriscaldamento.
