4. Setup
4.1 Installazzjoni tal-batterija
- Sib il-kompartiment tal-batterija fuq wara tal-multimeter.
- Uża tornavit żgħir biex tiftaħ l-għatu tal-batterija.
- Insert the provided 12V battery, observing the correct polarity (+ and -).
- Ibdel l-għatu tal-batterija u waħħalha bil-kamin.
4.2 Konnessjoni tal-wajers tat-test
The multimeter comes with a set of test leads. Connect them as follows:
- Daħħal il- iswed ċomb tat-test fil- COM ġakk (komuni).
- Daħħal il- aħmar ċomb tat-test fil- VΩmA jack for most measurements (Voltage, Resistance, Current).
5. Istruzzjonijiet Operattivi
Before taking any measurements, ensure the meter is set to the correct function and range. If the value is unknown, start with the highest range and work downwards.
5.1 Power On/Off and Function Selection
- To turn on the meter, rotate the central dial from the 'OFF' position to the desired measurement function.
- To turn off the meter, rotate the central dial back to the 'OFF' position.
5.2 DC VoltagKejl tal-e (V=)
- Set the rotary dial to the desired DC Voltage range (2V, 20V, 200V, or 500V).
- Qabbad il-wajer tat-test aħmar man-naħa pożittiva (+) taċ-ċirkwit u l-wajer tat-test iswed man-naħa negattiva (-).
- Aqra l-voltagIl-valur fuq il-wiri.
5.3 AC VoltagKejl tal-e (V~)
- Set the rotary dial to the desired AC Voltage range (200V or 500V).
- Qabbad il-wajers tat-test mal-vultaġġ ACtagsors e.
- Aqra l-voltagIl-valur fuq il-wiri.
5.4 DC Current Measurement (mA=)
Attenzjoni: Never connect the meter in parallel for current measurement. Always connect in series with the circuit.
- Set the rotary dial to the 200mA DC Current range.
- Break the circuit and connect the meter in series, ensuring the current flows through the meter.
- Aqra l-valur attwali fuq id-displej.
5.5 Kejl tar-Reżistenza (Ω)
- Ensure the circuit or component is de-enerġizzat before measuring resistance.
- Set the rotary dial to the desired Resistance range (2KΩ, 20KΩ, 200KΩ, or 2MΩ).
- Qabbad il-wajers tat-test mal-komponent li għandu jitkejjel.
- Aqra l-valur tar-reżistenza fuq il-wiri.
5.6 Test tad-Dijodi (→|)
- Set the rotary dial to the Diode Test function.
- Qabbad il-wajer tat-test aħmar mal-anodu u l-wajer tat-test iswed mal-katodu tad-dijodu.
- Id-displej se juri l-volum 'il quddiemtagwaqgħa e. Dawwar il-wajers; qari ta' ċirkwit miftuħ (OL) jindika dajowd tajjeb.
5.7 Test tal-Kontinwità ())))
- Set the rotary dial to the Continuity Test function.
- Qabbad il-wajers tat-test madwar iċ-ċirkwit jew il-komponent.
- Ħoss li jinstema' jindika kontinwità (reżistenza baxxa). Id-displej se juri l-valur tar-reżistenza.
6. Manutenzjoni
6.1 Sostituzzjoni tal-batterija
When the battery symbol appears on the display, the 12V battery needs to be replaced. Follow the steps in Section 4.1.
6.2 Tindif
Imsaħ il-kaxxa tal-miter b'reklamaramp drapp u deterġent ħafif. Tużax sustanzi abrażivi jew solventi. Kun żgur li l-miter ikun niexef qabel l-użu.
6.3 Ħażna
If the meter is not used for an extended period, remove the battery to prevent leakage. Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.
7 Issolvi l-problemi
- L-ebda wiri jew wiri dgħajjef: Iċċekkja l-batterija. Ibdelha jekk meħtieġ.
- Qari mhux korrett:
- Ensure the test leads are properly connected to the correct jacks.
- Verify the rotary dial is set to the correct function and range.
- Check the test leads for damage or breaks.
- "OL" (Tagħbija żejda) murija: The measured value exceeds the selected range. Switch to a higher range or check the circuit.
