4. Impostazione
Before using your multimeter, ensure it is properly set up.
4.1 Installazione della batteria
- Assicurarsi che il multimetro sia spento.
- Locate the battery compartment on the back of the device (refer to Image 3.2).
- Utilizzare un cacciavite per aprire il coperchio della batteria.
- Insert the required 1.5V batteries (or 9V battery if applicable, as shown in Image 8.1) according to the polarity markings.
- Chiudere saldamente il coperchio della batteria.
4.2 Collegamento del puntale di prova
- Connect the black test lead to the 'COM' input terminal.
- Connect the red test lead to the appropriate input terminal based on the measurement function:
- Per voltage, Resistance, Capacitance, Frequency, Diode, Continuity, and Temperature measurements, connect the red lead to the 'V/Ω/Hz/(t)/°C' terminal.
- For mA or µA current measurements, connect the red lead to the 'mA µA' terminal.
- For 20A current measurements, connect the red lead to the '20A' terminal.
- Assicurarsi che tutti i collegamenti siano saldi e sicuri.
5. Istruzioni per l'uso
This section details how to perform various measurements and utilize the multimeter's functions.
5.1 Misurazioni di base
- Voltage (AC/DC) Measurement:
Ruotare l'interruttore rotante su 'V~' (Volume ACtage) o 'V-' (Vol. 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. - Misura della resistenza:
Turn the rotary switch to the 'Ω' position. Connect the test leads across the component. Ensure the circuit is de-energized before measuring resistance. - Misurazione della capacità:
Turn the rotary switch to the 'F' (Capacitance) position. Connect the test leads across the capacitor. Ensure the capacitor is discharged before measurement. - Misura della temperatura:
Turn the rotary switch to the '°C/°F' position. Connect the K-type thermocouple (included) to the input terminals. The temperature will be displayed. - Misurazione della frequenza (Hz):
Ruotare il selettore rotativo in posizione 'Hz'. Collegare i puntali di prova alla sorgente del segnale. - Prova del diodo:
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 voltagVerrà visualizzato il rilascio. - Test di continuità:
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 Funzioni speciali
- Vero valore efficace: The OW18E features True RMS measurement, providing accurate readings for both sinusoidal and non-sinusoidal AC waveforms.
- Volume senza contattotage (NCV) Rilevamento: 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 viene rilevato.
- Retroilluminazione: Press the backlight button to illuminate the LCD for improved visibility in low-light conditions.
- Data Hold: Premere il pulsante 'HOLD' per bloccare la lettura corrente sul display. Premere nuovamente per rilasciare.
- Misurazione del valore relativo: This function allows you to measure the difference between a current reading and a stored reference value.
- Torcia elettrica: The built-in flashlight can be activated to illuminate the work area.
