2. Informazzjoni dwar is-Sigurtà

Dejjem segwi l-prekawzjonijiet ta' sigurtà li ġejjin biex tevita korriment personali jew ħsara lill-multimetru:

• Teċċedix il-valuri massimi tad-dħul għal kwalunkwe firxa.
• Ensure the test leads are properly connected and the rotary switch is set to the correct range before making measurements.
• Avoid touching the metal tips of the test leads when connected to a circuit.
• Tużax il-multimetru jekk jidher li huwa bil-ħsara jew jekk il-wajers tat-test huma mċarrtin.
• Always disconnect power to the circuit before measuring resistance, continuity, or diodes.
• Ibdel il-batterija meta jidher l-indikatur ta' batterija baxxa biex tiżgura qari preċiż.

4. Setup

Before first use, or when the low battery indicator appears, install or replace the 9V battery.

1. Installazzjoni tal-batterija: Locate the battery compartment on the back of the multimeter. Use a screwdriver to open the cover. Insert a 9V battery, observing the correct polarity. Close the cover securely.
2. Konnessjoni tal-wajers tat-test: Insert the black test lead into the 'COM' (Common) jack. Insert the red test lead into the 'VΩmA' jack for voltage, resistance, and small current measurements. For high current (up to 10A), insert the red lead into the '10ADC' jack.

5. Istruzzjonijiet Operattivi

This multimeter offers a range of measurement capabilities. Always ensure the correct function is selected and leads are connected appropriately.

• Kejl AC/DC Voltage:
  Set the rotary switch to the 'V~' (AC Voltage) jew 'V-' (Volum DCtage) range. Connect the test leads in parallel to the circuit or component being measured. Read the value on the LCD.
• Kejl tal-kurrent DC:
  Set the rotary switch to the 'A-' (DC Current) range. Ensure the red lead is in the appropriate current jack (VΩmA for mA, 10ADC for 10A). Connect the multimeter in series with the circuit. Read the value on the LCD.
• Measuring Resistance (Ω):
  Set the rotary switch to the 'Ω' (Resistance) range. Ensure the circuit is de-energized. Connect the test leads across the component. Read the value on the LCD.
• Test ta' Kontinwità:
  Set the rotary switch to the continuity symbol (speaker icon). Connect the test leads across the circuit or component. An audible beep indicates continuity (low resistance).
• Test tad-Diode:
  Set the rotary switch to the diode symbol. Connect the red lead to the anode and the black lead to the cathode of the diode. The display will show the forward voltagwaqgħa e. Dawwar il-wajers biex tiċċekkja għal ċirkwit miftuħ.
• Transistor HFE Test:
  Set the rotary switch to the 'hFE' range. Insert the transistor's emitter, base, and collector leads into the corresponding sockets on the multimeter. The display will show the transistor's HFE value.
• Test tal-batterija:
  Set the rotary switch to the '1.5V' or '9V' battery test range. Connect the test leads to the battery terminals (red to positive, black to negative). The display will show the battery voltage.
