5. Postavljanje

5.1. Ugradnja baterije

1. Provjerite je li mjerač ISKLJUČEN.
2. Pronađite odjeljak za baterije na stražnjoj strani mjerača.
3. Pomoću odvijača odvrnite vijak koji pričvršćuje poklopac baterije.
4. Pažljivo uklonite poklopac baterije.
5. Connect a 9V battery to the battery clips, observing correct polarity.
6. Stavite bateriju u odjeljak i vratite poklopac, pričvrstivši ga vijkom.

5.2. Spajanje ispitnog kabela

Always connect the test leads correctly for the desired measurement function.

• Za većinu volumenatage, resistance, continuity, and diode measurements, insert the red test lead into the VΩµA input jack and the black test lead into the COM input jack.
• For current measurements up to 600mA, insert the red test lead into the VΩµA input jack and the black test lead into the COM input jack.
• For current measurements up to 10A, insert the red test lead into the 10A input jack and the black test lead into the COM input jack.

5.3. Bluetooth Datalogging Module (DAT12)

The DAT12 module enables wireless communication with smart devices.

1. Insert the DAT12 module into the dedicated port on the top of the multimeter.
2. Download the free ExView W-Series app from your device's app store (iOS or Android).
3. Omogućite Bluetooth na pametnom uređaju.
4. Otvorite ExView W-Series app and follow the on-screen instructions to pair with the MM750W.

6. Operacija

6.1. Osnovna mjerenja

Turn the rotary switch to the desired function. The display will show the measurement value.

• Voltage (V~, V-): Odaberite AC ili DC voltage. Spojite mjerne kabele paralelno s krugom.
• Current (A~, A-): Select AC or DC current. Connect test leads in series with the circuit. Ensure correct input jack (µA/mA or 10A).
• Otpor (Ω): Turn off power to the circuit. Connect test leads across the component.
• Kontinuitet ()))): Turn off power. Connect test leads across the circuit. A tone indicates continuity.
• Test diode (→|): Turn off power. Connect test leads across the diode.

6.2. Napredne funkcije

• Bezkontaktni AC Voltage (NCV): Position the top of the meter near an AC voltage source. The NCV indicator will illuminate, and an audible tone will sound if AC voltage je otkriven.
• Type K Temperature (Temp): Insert the Type K bead wire probe into the VΩµA and COM jacks (observing polarity). Select the temperature function.
• MAX / MIN: Press the MAX/MIN button to record the maximum and minimum readings during a measurement session.
• Relativni način rada (REL): Press the REL button to store the current reading as a reference and display subsequent measurements as a deviation from this reference.
• Frequency/Duty Cycle (Hz/%): Select the appropriate function to measure frequency or duty cycle of an AC signal.
