2. Informació de seguretat

WARNING: To avoid possible electric shock, fire, or personal injury, please read all safety information before using the product.

• Always ensure the multimeter is in the correct function and range before making measurements.
• No apliqueu més del volum nominaltage, tal com està marcat al comptador, entre els terminals o entre qualsevol terminal i terra.
• Tingueu precaució quan treballeu amb voltagper sobre de 30 V CA RMS, 42 V pic o 60 V CC. Aquests voltagsuposen un risc de xoc.
• Before measuring current, ensure the circuit is de-energized and the meter is connected in series with the load.
• Never measure resistance, continuity, or diode on a live circuit.
• Inspeccioneu els cables de prova per detectar danys a l'aïllament o metall exposat abans d'utilitzar-los. Substituïu-los si estan danyats.
• No feu funcionar el mesurador si sembla danyat o si la carcassa està oberta.
• Remove test leads from the meter before opening the battery cover or fuse cover.
• Substituïu la bateria tan bon punt aparegui l'indicador de bateria baixa per garantir lectures precises.
• Complir els codis de seguretat locals i nacionals.

4. Configuració

4.1 Instal·lació de la bateria

The ANENG V7 Multimeter typically uses standard batteries (e.g., AA or 9V, check the battery compartment for specifics). To install or replace batteries:

1. Ensure the multimeter is turned OFF and disconnect all test leads from the input terminals.
2. Localitzeu la tapa del compartiment de la bateria a la part posterior de la unitat.
3. Utilitzeu un tornavís per obrir el compartiment de la bateria.
4. Insert new batteries, observing the correct polarity (+ and -).
5. Substituïu la tapa del compartiment de la bateria i fixeu-la amb el cargol.

4.2 Connexió dels cables de prova

Always connect the black test lead to the "COM" (common) jack. Connect the red test lead to the appropriate input jack based on the measurement you intend to make:

• Per al voltage, Resistance, Capacitance, Frequency, Diode, Continuity, and Temperature measurements: Connect the red lead to the "VΩHz-II+" jack.
• For Current (mA/µA) measurements: Connect the red lead to the "mAµA" jack.
• For High Current (A) measurements: Connect the red lead to the "20A" jack.

5. Instruccions de funcionament

The ANENG V7 features both auto-ranging and manual mode capabilities. The intelligent recognition function simplifies operation for common measurements.

Figure 5.1: The intelligent anti-burn feature with smart recognition helps prevent damage from incorrect settings, especially when the rotary dial is set to 'AUTO'.

5.1 Basic Measurement Steps

1. Turn the rotary dial to the desired function (e.g., V~ for AC Voltage, V- per a volúmenes de corrent continutage, Ω for Resistance, etc.). For most common measurements, the "AUTO" setting will automatically detect the type of measurement.
2. Connect the test leads to the circuit or component you wish to measure, ensuring correct polarity and connection points.
3. Llegiu el valor de mesura a la pantalla LCD.
4. After measurement, disconnect the test leads from the circuit, then from the multimeter.
5. Turn the rotary dial to "OFF" when not in use to conserve battery life.

5.2 Funcions de mesura específiques

• DC/AC Voltage Measurement (V-, V~):

  Set the rotary dial to V- (DC) or V~ (AC) or AUTO. Connect test leads in parallel to the circuit. The meter will display the voltage valor.

• DC/AC Current Measurement (A, mA, µA):

  Set the rotary dial to the appropriate current range (A, mA, or µA). Connect the meter in series with the circuit. Ensure the circuit is de-energized before connecting the meter.

• Mesura de resistència (Ω):

  Set the rotary dial to Ω or AUTO. Ensure the circuit is de-energized. Connect test leads across the component. The meter will display the resistance value.
• Capacitance Measurement (F):

  Set the rotary dial to F or AUTO. Ensure the capacitor is discharged before measurement. Connect test leads across the capacitor terminals.

• Mesura de freqüència (Hz):

  Set the rotary dial to Hz or AUTO. Connect test leads to the signal source. The meter will display the frequency.

• Prova de díodes (→|):

  Set the rotary dial to the diode symbol. Connect the red lead to the anode and the black lead to the cathode. The meter displays the forward voltage gota.
• Prova de continuïtat ()))):

  Set the rotary dial to the continuity symbol. Connect test leads across the circuit or component. A built-in buzzer will sound if the resistance is below a certain threshold (typically <50Ω).

• Mesura de temperatura (°C/°F):

  Set the rotary dial to TEMP. Connect the temperature probe (thermocouple) to the input jacks. Place the probe on the object to be measured.

• Vol. Sense contactetage (NCV) Detecció:

  Set the rotary dial to NCV. Bring the top of the meter near a live AC voltagfont electrònica. El mesurador indicarà la presència de voltatge de CAtage through an audible beep and/or visual indicator.

5.3 Funcions especials

• Retenció de dades (HOLD): Press the "HOLD" button to freeze the current reading on the display. Press again to release.
• Il·luminació de fons/Llanterna: The meter features a backlight for the display and an integrated flashlight for illuminating the work area. Refer to Figure 3.4 for flashlight location.
• MAX/MIN: Press the "MAX/MIN" button to record the maximum and minimum values during a measurement session.
• REL (Relative Value Measurement): This function allows you to measure a value relative to a stored reference value.
• Apagat automàtic: To conserve battery, the meter will automatically power off after a period of inactivity.

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

When the low battery indicator appears on the display, replace the batteries immediately to ensure accurate readings. Refer to Section 4.1 for battery installation instructions.

6.3 Canvi de fusibles

If the current measurement function stops working, the fuse may need replacement. Refer to the specifications for the correct fuse type and rating. Fuse replacement should only be performed by qualified personnel.

7. Solució De Problemes

• No Display / Power On Issue:

  Check battery installation and ensure batteries are not depleted. Replace if necessary. Ensure the rotary dial is not in the "OFF" position.

• Lectures incorrectes:

  Verify the correct function and range are selected. Check test lead connections. Ensure batteries are not low. Calibrate if necessary (advanced users only).

• Current Measurement Not Working:

  Check if the fuse for the current input is blown. Replace if necessary (refer to Section 6.3).
• Continuity Buzzer Not Sounding:

  Ensure the circuit is de-energized. Check for open circuits or high resistance. The buzzer typically activates for resistance below 50Ω.
