5. Instrukcja obsługi
This section details how to perform various measurements and utilize the multimeter's functions.
5.1 Pomiary podstawowe
- Tomtage (AC/DC) Measurement:
Obróć przełącznik obrotowy na pozycję „V~” (objętość prądu przemiennego)tage) lub „V-” (tom DCtage) position. Connect the test leads in parallel to the circuit or component to be measured. The reading will appear on the LCD. - 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. - Pomiar rezystancji:
Turn the rotary switch to the 'Ω' position. Connect the test leads across the component. Ensure the circuit is de-energized before measuring resistance. - Pomiar pojemności:
Turn the rotary switch to the 'F' (Capacitance) position. Connect the test leads across the capacitor. Ensure the capacitor is discharged before measurement. - Pomiar temperatury:
Turn the rotary switch to the '°C/°F' position. Connect the K-type thermocouple (included) to the input terminals. The temperature will be displayed. - Pomiar częstotliwości (Hz):
Ustaw przełącznik obrotowy w pozycji „Hz”. Podłącz przewody pomiarowe do źródła sygnału. - Test diody:
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 voltagZostanie wyświetlona kropla. - Test ciągłości:
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 Funkcje specjalne
- Prawdziwa wartość skuteczna: The OW18E features True RMS measurement, providing accurate readings for both sinusoidal and non-sinusoidal AC waveforms.
- Objętość bezkontaktowatage (NCV) Wykrywanie: 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 voltage zostało wykryte.
- Podświetlenie: Press the backlight button to illuminate the LCD for improved visibility in low-light conditions.
- Przechowywanie danych: Naciśnij przycisk „HOLD”, aby zamrozić aktualny odczyt na wyświetlaczu. Naciśnij ponownie, aby zwolnić.
