5. Fametrahana

5.1. Fametrahana bateria

1. Ensure the meter is turned OFF.
2. Locate the battery compartment on the rear of the meter.
3. Ampiasao tournevis hanesorana ny visy izay mihazona ny fonon'ny bateria.
4. Esory tsara ny fonon'ny batterie.
5. Connect a 9V battery to the battery clips, observing correct polarity.
6. Apetraho ao anaty fitoeran-javatra ny bateria ary avereno apetraka ny fonony, ary fafao amin'ny visy.

5.2. Fifandraisana amin'ny Tariby Fitsapana

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

• Ho an'ny ankamaroan'ny voltage, 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. Alefaso ny Bluetooth amin'ny fitaovana ampiasainao.
4. Sokafy ny ExView W-Series app and follow the on-screen instructions to pair with the MM750W.

6. Fampandehanana

6.1. Fandrefesana fototra

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

• BOKYtage (V~, V-): Safidio ny AC na DC voltage. Connect test leads in parallel with the circuit.
• Current (A~, A-): Select AC or DC current. Connect test leads in series with the circuit. Ensure correct input jack (µA/mA or 10A).
• fanoherana (Ω): Turn off power to the circuit. Connect test leads across the component.
• Fitohizana ()))): Turn off power. Connect test leads across the circuit. A tone indicates continuity.
• Test diode (→|): Turn off power. Connect test leads across the diode.
