2. Інфармацыя па бяспецы

Always observe the following safety precautions to prevent personal injury and damage to the device:

  • Не спрабуйце рамантаваць або мадыфікаваць прыладу. Звяртайцеся па ўсё абслугоўванне да кваліфікаванага персаналу.
  • Do not operate the device in explosive atmospheres or in the presence of flammable gases or fumes.
  • Ensure proper polarity when connecting test leads to avoid damage to the device or the circuit under test.
  • Always disconnect power to the circuit before making resistance, capacitance, or diode measurements.
  • Будзьце асцярожныя пры працы з voltagвышэй за 30 В пераменнага току (RMS), 42 В пікавага значэння або 60 В пастаяннага току, бо гэта стварае небяспеку паражэння электрычным токам.
  • Трымайце прыладу сухім. Не падвяргайце яе ўздзеянню дажджу або вільгаці.
  • Clean the device only with a dry, soft cloth. Do not use abrasive cleaners or solvents.
