2. Informació de seguretat
WARNING: To avoid possible electric shock, fire, or personal injury, please read all safety information before using the product. Improper use can lead to severe injury or death.
- Assegureu-vos sempre que el multímetre estigui en la funció i el rang correctes abans de fer mesures.
- No supereu els valors d'entrada màxims per a cap interval.
- Inspect test leads for damage before each use. Do not use if insulation is damaged or bare metal is exposed.
- No feu servir el multímetre si sembla que està danyat o si no funciona correctament.
- Aneu amb compte quan treballeu amb volumtagper sobre de 30 V CA RMS, 42 V pic o 60 V CC. Aquests voltagsuposen un risc de xoc.
- Desconnecteu sempre l'alimentació del circuit i descarregueu totes les emissions d'alt volum.tagcondensadors abans de mesurar la resistència, la continuïtat, els díodes o la capacitància.
- The device is rated for 600V CAT I. Do not use for measurements in CAT II, CAT III, or CAT IV environments.
- Canvieu les piles quan aparegui l'indicador de bateria baixa per garantir lectures precises.
- No feu funcionar el mesurador en ambients amb gasos explosius, vapors o pols.

4.2. Connexió dels cables de prova
- Inseriu el cable de prova negre a la presa d'entrada "COM" (comú).
- Inseriu el cable de prova vermell a la presa d'entrada adequada per a la vostra mesura:
- Per al voltage (V), Resistance (Ω), Capacitance (F), Diode, Continuity, Frequency (Hz), and NCV measurements, insert the red lead into the "VΩHz" jack.
- For Current (mA) measurements, insert the red lead into the "mA" jack.
- For High Current (10A) measurements, insert the red lead into the "10A MAX FUSED" jack.

5. Instruccions de funcionament
5.1. Encendre/apagar
Turn the rotary dial from the "OFF" position to any desired measurement function to power on the multimeter. To power off, turn the rotary dial back to the "OFF" position.
The multimeter features an Apagat automàtic function to conserve battery life. It will automatically power off after a period of inactivity. Press any button or turn the rotary dial to wake it up.

Figure 6: Function turntable for selecting measurement modes.
5.2. Selecció de la funció
Rotate the central dial to select the desired measurement function. The available functions include:
- V~ (AC Voltage) / V- (DC Voltage): Measures alternating or direct current voltage. Use the "SEL" button to switch between AC and DC.
- mV~ (AC Millivolt) / mV- (DC Millivolt): Measures low alternating or direct current voltage. Use the "SEL" button to switch between AC and DC.
- Ω (Resistance): Mesura la resistència elèctrica.
- Hz (Frequency) / % (Duty Cycle): Measures frequency or duty cycle.
- NCV (vol sense contacte).tage): Detecta AC voltagi sense contacte directe.
- A~ (AC Current) / A- (DC Current): Measures alternating or direct current (10A range). Use the "SEL" button to switch between AC and DC.
- mA~ (AC Milliamps) / mA- (DC Milliamps): Measures low alternating or direct current. Use the "SEL" button to switch between AC and DC.
- Diode / Continuity / Capacitance: Measures diode forward voltage drop, checks circuit continuity, or measures capacitance. Use the "SEL" button to cycle through these functions.
5.3. Funcions del botó
- SEL: Selects between different measurement modes within a single rotary dial position (e.g., AC/DC voltage, Diode/Continuity/Capacitance).
- HOLD / *:
- Press briefly to activate Data Hold, freezing the current reading on the display. Press again to release.
- Press and hold to turn the display backlight ON or OFF.
- Press and hold to turn the flashlight ON or OFF (located on the back of the device).
5.4. Millivolt Value Jump (Correct Phenomenon)
When measuring in the millivolt (mV) range, it is normal to observe a non-zero reading even when the test leads are not connected to a circuit. This phenomenon can occur due to:
- Excessive changes in ambient temperature and humidity.
- Strong electric field or magnetic field interference.
To confirm the meter is functioning correctly, short-circuit the red and black test pens. The display should return to zero (0.00 mV). If it does not, ensure the corresponding input hole is inserted into the red and black pen line correctly.

6. Manteniment
6.1. Neteja
Netegeu el cas amb l'anunciamp drap i detergent suau. No utilitzeu abrasius ni dissolvents. Mantingueu els terminals d'entrada lliures de brutícia i humitat.
6.2. Substitució de la bateria
Quan el símbol de la bateria [battery icon] appears on the LCD, the batteries must be replaced. Refer to Section 4.1 for detailed battery installation instructions.
6.3. Substitució de fusibles
If the current measurement function fails, the fuse may need replacement. The ANENG V01B uses two fuses:
- 10A MAX FUSED: For the 10A current range.
- 600V CAT I FUSED 400mA: For the mA current range.
WARNING: To prevent damage to the multimeter or personal injury, always replace blown fuses with fuses of the specified type and rating.
- Assegureu-vos que el multímetre estigui apagat i que els cables de prova estiguin desconnectats.
- Remove the battery compartment cover and batteries as described in Section 4.1.
- Traieu amb cura la part posterior casing screws (if any, beyond battery cover) to access the internal circuit board.
- Locate the blown fuse(s) and gently remove them.
- Install new fuses of the correct type and rating.
- Torneu a muntar el multímetre, assegurant-vos que tots els cargols estiguin ben apretats.
