2. Informazzjoni dwar is-Sigurtà

WARNING: Read and understand all safety information and operating instructions before using this meter. Failure to do so may result in serious injury or death.

• Dejjem żomm mal-kodiċijiet tas-sigurtà lokali u nazzjonali.
• Tużax il-miter jekk jidher li huwa bil-ħsara jew jekk il-wajers tat-test huma bil-ħsara.
• Kun żgur li s-swiċċ tal-funzjoni jkun fil-pożizzjoni korretta għall-kejl li qed jitwettaq.
• Observe all terminal ratings and never exceed the maximum input limits.
• Oqgħod attent meta taħdem bil-voltages 'il fuq minn 30V AC RMS, 42V peak, jew 60V DC, għax dawn joħolqu periklu ta' xokk elettriku.
• Ilbes tagħmir protettiv personali (PPE) xieraq, bħal nuċċalijiet tas-sigurtà u ingwanti iżolati.
• The MM750W is rated for CAT IV 600V and CAT III 1000V. Understand the implications of these categories for safe measurement.

5. Setup

5.1. Installazzjoni tal-batterija

1. Kun żgur li l-miter ikun MITFI.
2. Sib il-kompartiment tal-batterija fuq wara tal-miter.
3. Uża tornavit biex tneħħi l-kamin li jżomm l-għatu tal-batterija.
4. Neħħi bir-reqqa l-għatu tal-batterija.
5. Connect a 9V battery to the battery clips, observing correct polarity.
6. Poġġi l-batterija fil-kompartiment u erġa’ poġġi l-għatu, billi twaħħlu bil-kamin.

5.2. Konnessjoni tal-wajer tat-test

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

• Għal ħafna mill-volumtage, 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.

6. Operazzjoni

6.1. Kejl Bażiku

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

• Voltage (V~, V-): Agħżel AC jew 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).
• Reżistenza (Ω): Turn off power to the circuit. Connect test leads across the component.
• Kontinwità ()))): Turn off power. Connect test leads across the circuit. A tone indicates continuity.
• Test tad-diode (→|): Turn off power. Connect test leads across the diode.
