2. Informazzjoni dwar is-Sigurtà
Dejjem segwi l-prekawzjonijiet ta' sigurtà li ġejjin biex tevita korriment personali jew ħsara lill-multimetru:
- Do not exceed the maximum input limits for any measurement range.
- Oqgħod attent ħafna meta taħdem bil-voltag'il fuq minn 30V AC RMS, 42V peak, jew 60V DC. Dawn il-volumitages joħolqu periklu ta' xokk.
- Qabel ma tibdel il-funzjonijiet, skonnettja ċ-ċomb tat-test miċ-ċirkwit li qed jiġi ttestjat.
- Do not operate the multimeter if it appears damaged or if the test leads are damaged.
- Kun żgur li l-għatu tal-batterija jkun magħluq sew qabel l-operazzjoni.
- Ibdel il-batterija meta jidher l-indikatur ta' batterija baxxa biex tiżgura qari preċiż.
- Osserva l-kodiċijiet tas-sigurtà lokali u nazzjonali kollha.
Warning: Incorrect use of this meter can cause damage, shock, or injury.

Figure 4: Illustration of the MAS830L package contents and typical applications.
4.2. Installazzjoni/Sostituzzjoni tal-batterija
The MAS830L uses one 9V 6F22 battery. If the low battery indicator appears on the display, or if the unit does not power on, replace the battery:
- Kun żgur li l-multimetru jkun MITFI u skonnettja l-wajers tat-test kollha.
- Sib l-għatu tal-kompartiment tal-batterija fuq wara tal-unità.
- Ħoll il-vit(i) taż-żamma u neħħi l-għatu.
- Carefully remove the old battery (if present) and disconnect it from the battery clip.
- Connect the new 9V 6F22 battery to the battery clip, observing correct polarity.
- Place the new battery into the compartment and replace the cover, securing it with the screw(s).
5. Istruzzjonijiet Operattivi
5.1. Operazzjoni Ġenerali
- Connect the black test lead to the "COM" input jack.
- Connect the red test lead to the appropriate input jack for the desired measurement:
- "VΩmA" for voltage, reżistenza, u kejl ta' kurrent żgħir.
- "10A" for high current measurements (up to 10A).
- Turn the rotary switch to the desired function and range.
- Connect the test leads to the circuit or component under test.
- Read the measurement value on the LCD display.
5.2. Funzjonijiet tal-Kejl
DC Voltage Measurement (V–):
- Issettja s-swiċċ rotatorju għall-Volum DC mixtieqtagfirxa e (eż., 200mV, 2V, 20V, 200V, 600V).
- Connect the red lead to the positive side and the black lead to the negative side of the DC source.
AC Voltage Measurement (V∼):
- Issettja s-swiċċ rotatorju għall-Volum AC mixtieqtagfirxa e (eż., 200V, 600V).
- Connect the test leads across the AC source.
DC Current Measurement (A–):
- Set the rotary switch to the desired DC Current range (e.g., 2mA, 20mA, 200mA, 10A).
- Importanti: For 10A measurements, move the red lead to the "10A" input jack.
- Qabbad il-multimetru f'serje maċ-ċirkwit.
Resistance Measurement (Ω):
- Set the rotary switch to the desired Resistance range (e.g., 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩ).
- Kun żgur li ċ-ċirkwit ma jkollux l-enerġija qabel ma tkejjel ir-reżistenza.
- Qabbad il-wajers tat-test mal-komponent.
Diode Test (▶):
- Issettja s-swiċċ rotatorju għall-pożizzjoni tat-Test tad-Diode.
- Qabbad il-wajer aħmar mal-anodu u l-wajer iswed mal-katodu tad-dijodu. Id-displej se juri l-volum 'il quddiem.tagwaqgħa e. Dawwar il-wajers biex tiċċekkja għal ċirkwit miftuħ.
Continuity Test (♫):
- Issettja s-swiċċ rotatorju għall-pożizzjoni tat-Test tal-Kontinwità.
