3. Introduïu les 3 piles AAA, assegurant-vos de la polaritat correcta (+/-).
4. Tanqueu bé la tapa del compartiment de la bateria.

3.2 Connexió del cable de prova

Proper connection of test leads is crucial for accurate and safe measurements:

1. Always remove the protective caps from the test leads before use.
2. Connecteu el cable de prova negre al COM Presa d'entrada (comuna).
3. Connect the red test lead to the appropriate input jack based on the measurement:
• Per al voltage, Resistance, Continuity, Diode, Capacitance, Frequency, and Temperature measurements, connect the red lead to the VΩHz/C/F jack.
• For Current measurements (mA), connect the red lead to the mA jack.
• For High Current measurements (10A), connect the red lead to the 10A jack.
4. Ensure both test leads are fully and securely inserted into their respective jacks.

4.1 Funcionament general

To begin a measurement:

1. Turn the central rotary switch to the desired measurement function (e.g., Voltage, Resistance, Current).
2. The multimeter features automatic range judgment, which simplifies operation by automatically selecting the appropriate measurement range.
3. Utilitza el SELECCIONA button to cycle through different measurement modes within a function (e.g., AC or DC voltage, different current ranges).
4. El REL button activates the relative value measurement function, allowing you to measure changes relative to a stored reference value.
5. El Hz/BL button can be used to toggle frequency measurement (if applicable to the selected function) and to activate the display backlight.
6. El MANTENIM/LLUM button serves two purposes: a short press will hold the current reading on the display, and a long press will activate the integrated flashlight.

4.2 Mesures específiques

The FY19XF multimeter supports a wide range of electrical measurements:

• DC/AC Voltage Mesura: Turn the rotary switch to the 'V' position. Use the SELECT button to choose between AC and DC. Connect the test leads in parallel across the component or circuit to measure voltage.
• DC/AC Current Measurement: Turn the rotary switch to the 'A' or 'mA' position. Use the SELECT button to choose between AC and DC. Connect the test leads in series with the circuit to measure current. Ensure the correct input jack (mA or 10A) is used for the expected current range.
• Mesura de la resistència: Turn the rotary switch to the 'Ω' position. Connect the test leads across the component to measure its resistance.
• Mesura de continuïtat: Turn the rotary switch to the continuity symbol (often shared with resistance or diode). Connect the test leads across the circuit or component. An audible beep indicates continuity (low resistance).
• Mesura de díodes: Turn the rotary switch to the diode symbol. Connect the test leads across the diode. The display will show the forward voltage gota.
• Mesura de la capacitat: Turn the rotary switch to the capacitance symbol. Connect the test leads across the capacitor.
• Mesura de freqüència: Turn the rotary switch to the 'Hz' position (or use the Hz/BL button in relevant modes). Connect the test leads to the signal source.
• Mesura de la temperatura: Turn the rotary switch to the '°C/°F' position. Connect the K-type thermocouple to the appropriate input jacks and place the probe on the object to be measured.
• Vol. Sense contactetagDetecció de e (NCV): Turn the rotary switch to the 'NCV' position. Bring the top of the multimeter near a live electrical source. The device will beep and indicate voltagpresència sense contacte directe.

5. Informació de seguretat

Your Mastfuyi Digital Multimeter FY19XF is designed with safety in mind. Please observe the following precautions:

• Smart Burnout Prevention and Overload Protection: The multimeter incorporates a smart burnout prevention chip with a ceramic fuse, offering full-range overload protection. It provides 250V burnout prevention if an incorrect measurement function is selected.
• Vol. Alttage Alerta: Un alt voltage alert with a red backlit display will activate if the measured voltage exceeds 36V, indicating a potential hazard. Exercise extreme caution when this alert is active.
• Misplaced Test Leads Alarm: An audible alarm will sound if test leads are inserted into the current measurement jack without the rotary switch being set to the correct current function, preventing accidental damage to the device and potential hazards.
• Always remove the protective caps from the test leads before making any measurements.
• Do not attempt to measure AC currents or voltages below 100mV if the device cannot display results. Consult the manual for specific measurement limitations.
• Ensure the rotary switch is set to the correct function before connecting the test leads to a circuit.
