2. Информация по технике безопасности

Во избежание поражения электрическим током или травм, а также для предотвращения повреждения осциллографа или подключенного оборудования, соблюдайте следующие меры предосторожности:

• Правильное заземление: 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.
• Правильно подключайте и отключайте устройства: 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.
• Соблюдайте все рейтинги терминалов: 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).
• Избегайте открытых участков схемы: Не прикасайтесь к открытым контактам или компонентам при наличии напряжения.
• Не работайте с предполагаемыми неисправностями: If you suspect damage to the instrument, have it inspected by qualified service personnel.
• Поддерживайте сухие условия: Не используйте прибор во влажных или сухих условиях.amp условия.
• Operate in a Well-Ventilated Area: Обеспечьте надлежащую вентиляцию, чтобы предотвратить перегрев.
