  2. Current (AC/DC) Measurement:
    Turn the rotary switch to the 'A~' (AC Current) or 'A-' (DC Current) position, selecting the appropriate range (µA, mA, or 20A). Connect the test leads in series with the circuit.
  3. Вымярэнне супраціву:
    Turn the rotary switch to the 'Ω' position. Connect the test leads across the component. Ensure the circuit is de-energized before measuring resistance.
  4. Вымярэнне ёмістасці:
    Turn the rotary switch to the 'F' (Capacitance) position. Connect the test leads across the capacitor. Ensure the capacitor is discharged before measurement.
  5. Вымярэнне тэмпературы:
    Turn the rotary switch to the '°C/°F' position. Connect the K-type thermocouple (included) to the input terminals. The temperature will be displayed.
  6. Frequency (Hz) Measurement:
    Turn the rotary switch to the 'Hz' position. Connect the test leads to the signal source.
  7. Дыёдны тэст:
    Turn the rotary switch to the 'Diode' symbol position. Connect the red lead to the anode and the black lead to the cathode of the diode. The forward voltagбудзе адлюстравана кропля.
  8. Тэст бесперапыннасці:
    Turn the rotary switch to the 'Continuity' symbol position. Connect the test leads across the circuit or component. A buzzer will sound if continuity is detected.

5.2 Спецыяльныя функцыі

  • Сапраўднае RMS: The OW18E features True RMS measurement, providing accurate readings for both sinusoidal and non-sinusoidal AC waveforms.
  • Бескантактавы выпtagвыяўленне e (NCV): Activate the NCV function to detect the presence of AC voltage without direct contact. The strength indicator will illuminate, and an audible alarm will sound if voltagе выяўляецца.
  • Падсвятленне: Press the backlight button to illuminate the LCD for improved visibility in low-light conditions.
  • Утрыманне дадзеных: Націсніце кнопку «HOLD», каб зафіксаваць бягучае паказанне на дысплеі. Націсніце яшчэ раз, каб адпусціць.
