2. Informații de siguranță

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

• Asigurați-vă întotdeauna că multimetrul este în funcția și intervalul corect înainte de a efectua măsurători.
• Nu aplicați mai mult decât volumul nominaltage, așa cum este marcat pe contor, între terminale sau între orice terminal și împământare.
• Aveți grijă când lucrați cu voltagpeste 30V AC RMS, 42V peak sau 60V DC. Aceste voltajetagreprezintă un pericol de șoc.
• 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.
• Verificați cablurile de testare pentru a depista izolația deteriorată sau metalul expus înainte de utilizare. Înlocuiți-le dacă sunt deteriorate.
• Nu utilizați contorul dacă acesta pare deteriorat sau dacă carcasa este deschisă.
• Remove test leads from the meter before opening the battery cover or fuse cover.
• Înlocuiți bateria imediat ce apare indicatorul de baterie descărcată pentru a asigura citiri precise.
• Respectați codurile de siguranță locale și naționale.

4. Configurare

4.1 Instalarea bateriei

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. Asigurați-vă că multimetrul este oprit și deconectați toate sondele de testare de la bornele de intrare.
2. Localizați capacul compartimentului bateriilor din spatele unității.
3. Folosiți o șurubelniță pentru a deschide compartimentul bateriei.
4. Insert new batteries, observing the correct polarity (+ and -).
5. Puneți la loc capacul compartimentului bateriei și fixați-l cu șurubul.

4.2 Conectarea cablurilor de testare

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:

• Pentru 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. Instrucțiuni de utilizare

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 Pași de bază ai măsurării

1. Turn the rotary dial to the desired function (e.g., V~ for AC Voltage, V- pentru Vol DCtage, 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. Citiți valoarea măsurată pe afișajul 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 Funcții specifice de măsurare

• 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 voltagvaloarea e.

• 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.

• Măsurarea rezistenței (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.

• Măsurarea frecvenței (Hz):

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

• Test diode (→|):

  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 picătură.
• Test de continuitate ()))):

  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).

• Măsurarea temperaturii (°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. Fără contacttage (NCV) Detectie:

  Set the rotary dial to NCV. Bring the top of the meter near a live AC voltage source. The meter will indicate the presence of AC voltage through an audible beep and/or visual indicator.

6.3 Înlocuirea siguranței

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. Depanare

• 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.

• Citiri incorecte:

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

• Măsurarea curentului nu funcționează:

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