2. Maklumat Keselamatan

To prevent electric shock or personal injury, and to avoid damage to the oscilloscope or connected equipment, observe the following safety precautions:

• Pembumian yang betul: 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.
• Connect and Disconnect Properly: 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.
• Perhatikan Semua Penilaian Terminal: 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).
• Avoid Exposed Circuitry: Do not touch exposed connections or components when power is present.
• Jangan Beroperasi dengan Kegagalan yang Disyaki: If you suspect damage to the instrument, have it inspected by qualified service personnel.
• Mengekalkan Keadaan Kering: Do not operate the instrument in wet or damp syarat.
• Operate in a Well-Ventilated Area: Pastikan pengudaraan yang betul untuk mengelakkan terlalu panas.
