Configuració
Instal·lació de la bateria
The multimeter comes with two 1.5V AAA batteries already installed. If replacement is needed, open the battery compartment on the back of the device, insert new batteries with correct polarity, and secure the cover.
Connexió de cables de prova
Insert the black test lead into the COM terminal and the red test lead into the appropriate input terminal based on your desired measurement (e.g., VΩmA for voltage, resistance, or low current; 10A for high current).
Instruccions de funcionament
VoltagMesura (CA/CC)
Turn the rotary switch to the 'V' position. The meter will automatically detect AC or DC voltage. Use the FUNC button to manually switch if needed. Connect the test leads across the circuit or component to measure voltage.

Figure 3: The multimeter is shown measuring AC voltage from a wall outlet and DC voltage from a car battery, demonstrating its versatile use.
Mesura de corrent (CA/CC)
For current up to 10A, turn the rotary switch to the '10A' position. For milliampere current, use the 'mA' position. Use the FUNC button to select AC or DC. Connect the multimeter in series with the circuit to measure current.

Figure 4: The multimeter is used to measure current in an electronic circuit, illustrating its application for current analysis.
Resistance and Capacitance Measurement
Turn the rotary switch to the 'Ω' (Ohms) position for resistance or 'F' (Farad) for capacitance. Use the FUNC button to select between these modes. Connect the test leads across the component to measure.

Figure 5: The multimeter measures resistance on a circuit board, demonstrating its capability for component testing.
Prova de díode i continuïtat
Turn the rotary switch to the diode/continuity symbol. Use the FUNC button to select between diode test and continuity test. For continuity, the buzzer will sound if resistance is below a certain threshold. For diode test, it measures the forward voltage gota.
Battery Test (1.5V, 9V, 12V)
Seleccioneu el volum de bateria desitjattage (1.5V, 9V, or 12V) on the rotary switch. Connect the test leads to the battery terminals. The multimeter's indicator light will turn red for low voltage i verd per a un volum suficienttage.

Vol. Sense contactetagProva e (NCV)
Turn the rotary switch to the 'NCV' position. Hold the NCV detector near the object to be tested. The meter will emit a quick beep and the red indicator light will turn on if a strong AC signal is detected.

Prova de cable en directe
Turn the rotary switch to the 'Live' position. Use the red test lead to probe the wire. The meter will indicate if the wire is live.

Figure 8: The multimeter is used to test for live wires in an electrical outlet, ensuring safety during electrical work.
Backlight and Flashlight
Press the Backlight/Flashlight button to activate the screen backlight for improved visibility in low-light conditions. Long press the same button to turn on the built-in flashlight.

Figure 9: The multimeter's backlight and flashlight features are shown in use, providing clear readings and illumination in dark spaces.
Manteniment
