• Няма дысплея/харчавання:
  • Праверце, калі Рэйтынг Выпtage Rotating Switch (10) is moved from "OFF".
  • Verify battery installation and polarity.
  • Replace batteries if the low battery indicator was previously shown or if batteries are old.
  • Ensure external power adapter (if used) is correctly connected and functional.
• "HV ON" Indicator Not Lighting Up During Test:
  • Забяспечце Кнопка TEST/STOP (5) is pressed firmly.
  • Check battery level. Insufficient power may prevent high voltagе пакаленне.
  • Verify test leads are properly connected.
• Unstable or Incorrect Readings:
  • Ensure test leads are securely connected to both the instrument and the device under test.
  • Verify the device under test is properly isolated and de-energized.
  • Праверце наяўнасць знешніх крыніц перашкод.
  • Ensure the correct test voltage and range are selected for the measurement.
  • Clean test points on the device under test.
• Over-range Indication (e.g., "OL" or "1"):
  • This indicates the measured value exceeds the selected range. Switch to a higher range using the Пераключальнік дыяпазону (6).
  • If still over-range on the highest setting, the resistance is extremely high, or there is an open circuit.
