2. Informazzjoni dwar is-Sigurtà
WARNING: To avoid electric shock or personal injury, and to prevent damage to the meter or to the equipment under test, observe the following safety rules:
- Dejjem kun żgur li l-multimetru huwa ssettjat għall-funzjoni u l-firxa korretti qabel ma tieħu l-kejl.
- Applikax aktar mill-vol nominalitage, kif immarkat fuq il-meter, bejn it-terminals jew bejn kwalunkwe terminal u ground ground.
- Uża kawtela kbira meta taħdem bil-voltag'il fuq minn 30V AC RMS, 42V peak, jew 60V DC. Dawn il-volumitages joħolqu periklu ta' xokk.
- Keep your fingers behind the probe barriers during measurements.
- Tużax il-miter jekk jidher li huwa bil-ħsara jew jekk il-wajers tat-test huma bil-ħsara.
- Kun żgur li l-għatu tal-batterija jkun magħluq sew qabel ma tħaddem il-miter.
- Remove test leads from the circuit before changing functions or ranges.
- Tħaddimx il-miter f'ambjenti b'gass, fwar jew trab splussiv.

4. Setup
4.1 Installazzjoni tal-batterija
The multimeter requires a 9V battery (not included). To install:
- Sib l-għatu tal-kompartiment tal-batterija fuq wara tal-multimetru.
- Remove the screw(s) securing the cover and lift it off.
- Connect a 9V battery to the battery clips, observing correct polarity (+ and -).
- Poġġi l-batterija fil-kompartiment u erġa’ poġġi l-għatu, billi twaħħlu bil-vit(i).
4.2 Konnessjoni tal-wajers tat-test
Qabbad il-wajers tat-test mal-jacks tad-dħul xierqa:
- Daħħal iċ-ċomb iswed tat-test fil- COM Ġakk (komuni).
- Daħħal iċ-ċomb aħmar tat-test fil- VΩmA jack għall-volumtage, resistance, and current measurements.
5. Istruzzjonijiet Operattivi
Before making any measurement, ensure the test leads are correctly connected and the rotary switch is set to the desired function and range.
5.1 Kejl DC Voltage (DCV)
The multimeter offers 4 DCV ranges: 2V, 20V, 200V, 500V.
- Set the rotary switch to the desired DCV range (e.g., 20V for typical battery checks). If the voltagJekk e ma tkunx magħrufa, ibda bl-ogħla firxa (500V) u naqqasha kif meħtieġ.
- Connect the red test probe to the positive (+) side of the circuit and the black test probe to the negative (-) side.
- Aqra l-voltage valur fuq il-wiri LCD.
5.2 Kejl AC Voltage (ACV)
The multimeter offers 2 ACV ranges: 200V, 500V.
- Set the rotary switch to the desired ACV range (e.g., 200V or 500V for household outlets).
- Qabbad il-probi tat-test mal-vultaġġ ACtagsors e.
- Aqra l-voltage valur fuq il-wiri LCD.
5.3 Kejl tal-Kurrent DC (DCA)
The multimeter offers 3 DCA ranges: 2mA, 20mA, 200mA.
- TWISSIJA: Qatt ma tqabbad il-multimetru b'mod parallel ma' voltagSors elettroniku meta tkejjel il-kurrent. Dan jista' jagħmel ħsara lill-miter u liċ-ċirkwit.
- Set the rotary switch to the desired DCA range.
- Iftaħ iċ-ċirkwit fejn trid tkejjel il-kurrent.
- Connect the multimeter in series with the circuit, ensuring the current flows through the meter. The red probe connects to the higher potential side, and the black probe to the lower potential side.
- Aqra l-valur kurrenti fuq il-wiri LCD.
5.4 Measuring Resistance (Ohms)
The multimeter offers 5 Ohms ranges: 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩ.
- TWISSIJA: Kun żgur li ċ-ċirkwit jew il-komponent li qed jiġi ttestjat ikun kompletament diżenerġizzat qabel ma tkejjel ir-reżistenza.
- Set the rotary switch to the desired Ohms range.
- Connect the test probes across the component whose resistance you want to measure.
- Aqra l-valur tar-reżistenza fuq id-displej LCD.
5.5 Diode Check
This function allows you to test diodes for proper operation.
- Set the rotary switch to the Diode Check symbol (usually a diode icon).
- Connect the red test probe to the anode of the diode and the black test probe to the cathode. A forward voltage drop (e.g., 0.5V to 0.7V for silicon diodes) should be displayed.
- Reverse the probes. The display should show "OL" (Overload) or a very high resistance, indicating an open circuit. If both directions show a reading or "OL", the diode may be faulty.
6. Manutenzjoni
6.1 Tindif
Imsaħ il-każ bl-adamp drapp u deterġent ħafif. Tużax abrażivi jew solventi.
6.2 Sostituzzjoni tal-batterija
When the battery low indicator appears on the display, replace the 9V battery as described in the "Battery Installation" section (4.1). Always use a fresh 9V alkaline battery.
6.3 Sostituzzjoni tal-Fjus
If the current measurement function stops working, the fuse may need replacement. Refer to the specifications for the correct fuse type. Fuse replacement typically involves opening the back casing tal-multimetru. Jekk m'intix ċert, ikkonsulta tekniku kwalifikat.
