2. Enfòmasyon sou Sekirite

Always adhere to safety precautions when using the multimeter to prevent electric shock or damage to the device. This multimeter is IEC Rated CAT III 1000V and CAT IV 600V, CE, and RoHS certified. It incorporates anti-burn protection with double ceramic fuses and a thermistor protection circuit. High Voltage Protection is active on all ranges, and the unit is double insulated.

• Always inspect the multimeter and test leads for any damage before use.
• Pa sèvi ak miltimèt la si li sanble domaje oswa si fil tès yo chire.
• Asire w ke ou chwazi fonksyon ak ranje ki kòrèk la anvan ou pran mezi yo.
• Pa depase valè maksimòm yo pou okenn entèval.
• Pran prekosyon lè w ap travay ak voltagki pi wo pase 30V AC RMS, 42V pik, oubyen 60V DC, paske sa yo poze yon danje pou elektrisite.
• Toujou dekonekte kouran sikwi a anvan ou mezire rezistans, kapasitans, oswa kontinwite.
• Replace batteries promptly when the low battery indicator appears.

6. Operasyon Enstriksyon

Turn the rotary dial to select the desired measurement function. The multimeter will automatically select the appropriate range (auto-ranging).

6.1 Measuring DC/AC Voltage (V)

1. Turn the rotary dial to the 'V' position (DC or AC as indicated).
2. Connect the test leads in parallel to the circuit or component being measured.
3. Li voltage valè sou ekspozisyon an.

6.2 Measuring DC/AC Current (A)

1. Turn the rotary dial to the 'mA' or '10A' position, depending on the expected current.
2. For currents up to 600mA, use the 'mAµA' jack. For currents up to 10A, use the '10A' jack.
3. Konekte fil tès yo an seri ak kous la.
4. Li valè aktyèl la sou ekran an.

6.3 Mezire Rezistans (Ω)

1. Turn the rotary dial to the 'Ω' position.
